while allowing seamless migration to 10 Gigabit Ethernet, virtual machine-aware Unified Fabric technologies.

Cisco Nexus 5000 Series Hardware Features

The Cisco Nexus 5000 Series cut-through switching architecture supports line-rate 10 Gigabit Ethernet with

low-latency and predictable performance on all ports. These switches also support 10/1 Gigabit Ethernet

mode on a subset of the fixed ports to provide connectivity for Gigabit Ethernet attached servers and network

The Cisco Nexus 5000 Series supports Fibre Channel over Ethernet that enables consolidation of LAN, SAN

and cluster traffic onto a single, Unified Fabric, which greatly simplifies network infrastructure, increases

flexibility and reduces costs. By connecting to existing Fibre Channel storage arrays, FCoE protects existing

storage investments while simplifying in-rack cabling and reducing power and cooling overhead.

Cisco Nexus 5000 Series supports standards-based IEEE Data Center Bridging (DCB) capabilities that allows

the switches to support multiple traffic classes — LAN, SAN, and cluster — over the same link, while retaining

individual traffic treatment.

In addition to standard 10 Gigabit network interface cards (NICs), the Cisco Nexus 5000 Series supports

standards-based Fibre Channel over Ethernet consolidated network adapters (CNAs) that combine Ethernet

NICs and Fibre Channel host bus adapters (HBAs). These CNAs make the transition to a Unified Fabric

transparent and consistent with existing practices, management software, and operating system drivers.

The Cisco Nexus 5000 Series is compatible with third-party integrated transceivers and Twinax cabling

solution that delivers very low latency at a low cost, making the product line an excellent match for cluster

environments.

    Associating a Fabric Extender to a Fabric Interface

    A Fabric Extender is connected to the switch through physical Ethernet interfaces or an EtherChannel. By default, the switch does not allow the attached Fabric Extender to connect until it has been assigned a chassis ID and is associated with the connected interface.

    Note The Fabric Extender may connect to the switch through a number of separate physical Ethernet interfaces or at most one EtherChannel interface.

    Caution In Release 4.0(1a)N2(1), you cannot connect the Ethernet interfaces of the Expansion Modules in the Cisco Nexus 5000 Series switch to a Fabric Extender. Only the Ethernet interfaces on the switch chassis (slot 1) can be used as fabric interfaces.

    This section includes the following topics:

    • Associating a Fabric Extender to an Ethernet Interface
    • Associating a Fabric Extender to an EtherChannel
    • Disassociating a Fabric Extender from an Interface

    Associating a Fabric Extender to an Ethernet Interface

    To associate the Fabric Extender to an Ethernet interface, perform this task:

    switch# configure terminal

    Enters configuration mode.

    switch(config)# interface ethernet slot / port

    Specifies an Ethernet interface to configure.

    switch(config-if)# switchport mode fex-fabric

    Sets the interface to support an external Fabric Extender.

    switch(config-if)# fex associate chassis

    Associates the chassis ID to the Fabric Extender unit attached to the interface. The range of the chassis ID is from 100 to 199.

    switch# show interface ethernet port / slot fex-intf

    (Optional) Displays the association of a Fabric Extender to an Ethernet interface.

    This example shows how to associate the Fabric Extender to an Ethernet interface on the switch:

    switch# configure terminal
    switch(config)# interface ethernet 1/40
    switch(config-if)# switchport mode fex-fabric
    switch(config-if)# fex associate 100

    This example shows how to display the association of the Fabric Extender and the switch:

    switch# show interface port-channel channel fex-intf

    (Optional) Displays the association of a Fabric Extender to an EtherChannel interface.

    This example shows how to associate the Fabric Extender to an EtherChannel interface on the switch:

    switch# configure terminal
    switch(config)# interface port-channel 4
    switch(config-if)# switchport mode fex-fabric
    switch(config-if)# fex associate 100
    switch(config-if)# exit
    switch(config)# interface ethernet 1/37
    switch(config-if)# switchport mode fex-fabric
    switch(config-if)# fex associate 100
    switch(config-if)# channel-group 4
    switch(config-if)# exit
    switch(config)# interface ethernet 1/38
    switch(config-if)# switchport mode fex-fabric
    switch(config-if)# fex associate 100
    switch(config-if)# channel-group 4
    switch(config-if)# exit
    switch(config)# interface ethernet 1/39
    switch(config-if)# switchport mode fex-fabric
    switch(config-if)# fex associate 100
    switch(config-if)# channel-group 4
    switch(config-if)# exit
    switch(config)# interface ethernet 1/40
    switch(config-if)# switchport mode fex-fabric
    switch(config-if)# fex associate 100
    switch(config-if)# channel-group 4

    Note You have to associate each Ethernet interface that is a members of the EtherChannel as a fabric interface as shown in the above example.

    Disassociating a Fabric Extender from an Interface

    To disassociate the Fabric Extender from an interface, perform this task:

    switch(config-if)# no fex associate

    Disassociates the Fabric Extender unit attached to the interface.

    Configuring the Fabric Extender

    To configure global features for a Fabric Extender, perform this tasks:

    switch# configure terminal

    Enters configuration mode.

    switch(config)# fex chassis

    Enters configuration mode for the specified Fabric Extender chassis ID. The range of the chassis ID is from 100 to 199.

    switch(config-fex)# description desc

    Specifies the description. The default is the string FEX xxxx where xxxx is the chassis ID. If the chassis ID is 123, the description is FEX0123.

    switch(config-fex)# no description

    Deletes the description.

    switch(config-fex)# pinning max-links uplinks

    Defines the number of uplinks. The default is 1. The range is from 1 to 4.

    This command is only applicable if the Fabric Extender is connected to its parent switch using one or more statically pinned fabric interfaces. There can only be one EtherChannel connection.

    switch(config-fex)# no pinning max-links

    Resets the number of uplinks to the default.

    switch(config-fex)# serial serial

    Defines a serial number string. If this command is configured, then a switch will only allow the corresponding chassis ID to associate (using the fex associate command) if the Fabric Extender reports a matching serial number string.

    Configuring a serial number other than that of the given Fabric Extender will force the Fabric Extender offline.

    switch(config-fex)# no serial

    Deletes the serial number string.

    Turns on the beacon LED. This LED allows you to locate a specific Fabric Extender in a rack.

    switch(config-fex)# no beacon

    Turns off the beacon LED.

    Caution Changing the number of uplinks with the pinning max-links command or the no pinning max-links command disrupts all the host interface ports of the Fabric Extender.

    Redistributing the Links

    When you provision the Fabric Extender with statically pinned interfaces (see the “Static Pinning Fabric Interface Connection” section), the downlink host interfaces on the Fabric Extender are pinned to the fabric interfaces in the order they were initially configured. If you want to maintain a specific relationship of host interfaces to fabric interface across reboots, you should re-pin the links.

    You may want to perform this function in these two situations:

    • A change in the max-links configuration.
    • If you need to maintain the pinning order of host interfaces to fabric interfaces.

    Changing the Number of Links

    If you initially configured port 33 on the parent switch as your only fabric interface, all 48 host interfaces are pinned to this port. If you provision another port, for example 35, then you must enter the pinning max-links 2 command to redistribute the host interfaces. All host interfaces are brought down and host interfaces 1 to 24 are pinned to fabric interface 33 and host interfaces 25 to 48 are pinned to fabric interface 35.

    Maintaining the Pinning Order

    The pinning order of the host interfaces is initially determined by the order in which the fabric interfaces were configured. In this example, four fabric interfaces were configured in the following order:

    switch# show interface ethernet 1/35 fex-intf
    Fabric FEX
    Interface Interfaces

    Eth100/1/28 Eth100/1/27 Eth100/1/26 Eth100/1/25

    Eth100/1/40 Eth100/1/39 Eth100/1/38 Eth100/1/37

    The next time that you reboot the Fabric Extender, the configured fabric interfaces are pinned to the host interfaces in an ascending order by port number of the fabric interface. If you want to configure the same fixed distribution of host interfaces without restarting the Fabric Extender, enter the fex pinning redistribute command (see the “Static Pinning Fabric Interface Connection” section).

    To redistribute the host interfaces on the Fabric Extender, perform this task:

    switch# fex pinning redistribute chassis

    Redistributes the host connections. The range of the chassis ID is from 100 to 199.

    This example shows how to redistribute the host interfaces on a Fabric Extender:

    switch# fex pinning redistribute 100

    Caution The fex pinning redistribute command disrupts all the host interface ports of the Fabric Extender.

    Upgrading the Fabric Extender

    To upgrade a Cisco Nexus 2000 Series Fabric Extender, perform these steps:

    Step 1 Download the new kickstart and system images to the parent switch.

    Step 2 Enter the install all command.

    While the installation is in progress, the Fabric Extender remains online.

    The new image is pushed to the Fabric Extender by the parent switch. Once the software image has successfully been installed, the parent switch reboots. The Fabric Extender is also rebooted automatically to maintain the software version compatibility between the parent switch and the Fabric Extender. When the parent switch comes up, it rediscovers the Fabric Extender and brings it online.

    This process is the least disruptive process for the hosts and servers connected to the Fabric Extender.

    Displaying Fabric Extender Information

    This section describes the show commands that are available to display the configuration and status of the Fabric Extender and includes the following topics:

    • Displaying Configuration Information
    • Displaying Chassis Management Information

    Displaying Configuration Information

    To display configuration information about the defined interfaces, perform one of these tasks:

    switch# show fex [ chassis [ detail ]

    Displays information about a specific Fabric Extender or all attached units.

    switch# show interface type number fex-intf

    Displays the Fabric Extender ports pinned to a specific switch interface.

    switch# show interface fex-fabric

    Displays the switch interfaces that have detected a Fabric Extender uplink.

    This example shows how to display all the attached Fabric Extender units:

    Information About the Cisco Nexus 2000 Series Fabric Extender

    The Cisco Nexus 2000 Series Fabric Extender is a highly scalable and flexible server networking solution that works with Cisco Nexus 5000 Series switches to provide high-density, low-cost connectivity for server aggregation. Scaling across 1-Gigabit Ethernet, 10-Gigabit Ethernet, unified fabric, rack, and blade server environments, the Fabric Extender is designed to simplify data center architecture and operations.

    The Fabric Extender integrates with its parent switch, a Cisco Nexus 5000 Series switch, to allow automatic provisioning and configuration taken from the settings on the parent switch. This integration allows large numbers of servers and hosts to be supported using the same feature set as the parent switch, including security and quality-of-service (QoS) configuration parameters, with a single management domain as shown in the following figure. The Fabric Extender and its parent switch enable a large multi-path, loop-free, active-active data center topology without the use of Spanning Tree Protocol (STP).

    Figure 1. Single Management Domain

    A single management domain is controlled by the parent switch.

    The Cisco Nexus 2000 Series Fabric Extender forwards all traffic to its parent Cisco Nexus 5000 Series switch over 10-Gigabit Ethernet fabric uplinks, allowing all traffic to be inspected by policies established on the Cisco Nexus 5000 Series switch.

    No software is included with the Fabric Extender . Software is automatically downloaded and upgraded from its parent switch.

    Fabric Extender Terminology

      Fabric interface—A 10-Gigabit Ethernet uplink port designated for connection from the Fabric Extender to its parent switch. A fabric interface cannot be used for any other purpose. It must be directly connected to the parent switch.
    Note A fabric interface includes the corresponding interface on the parent switch. This interface is enabled when you enter the switchport mode fex-fabric command.
    Note Do not connect a bridge or switch to a host interface. These interfaces are designed to provide end host or server connectivity.

    Fabric Extender Features

    The Cisco Nexus 2000 Series Fabric Extender allows a single switch—and a single consistent set of switch features—to be supported across a large number of hosts and servers. By supporting a large server-domain under a single management entity, policies can be enforced more efficiently.

    Some of the features of the parent switch cannot be extended onto the Fabric Extender .

    • Layer 2 Host Interfaces
    • Host EtherChannel
    • VLANs and Private VLANs
    • Virtual Port Channels
    • Fibre Channel over Ethernet Support
    • Protocol Offload
    • Quality of Service
    • Access Control Lists
    • IGMP Snooping
    • Switched Port Analyzer
    • Fabric Interface Features

    Layer 2 Host Interfaces

    • All Fabric Extender host interfaces run as spanning tree edge ports with BPDU Guard enabled and cannot be configured as Spanning Tree network ports.
    • Servers utilizing active/standby teaming, 802.3ad port channels, or other host-based link redundancy mechanisms can be connected to Fabric Extender host interfaces.
    • Any device running spanning tree connected to a Fabric Extender host interface will result in that host interface being placed in an error-disabled state when a BPDU is received.
    • Any edge switch that leverages a link redundancy mechanism not dependent on Spanning Tree such as Cisco Flexlink or vPC (with BPDUFilter enabled) may be connected to a Fabric Extender host interface. Since spanning tree is not utilized to eliminate loops, care must be taken to ensure a loop-free topology below the Fabric Extender host interfaces.

    You can enable host interfaces to accept Cisco Discovery Protocol (CDP) packets. This protocol only works when it is enabled for both ends of a link.

    Note

    CDP is not supported on fabric interfaces when the Fabric Extender is configured in a virtual port channel (vPC) topology.

    Ingress and egress packet counters are provided on each host interface.

    For more information about BPDU Guard and CDP , see the Cisco Nexus 5000 Series NX-OS Layer 2 Switching Configuration Guide .

    Host EtherChannel

    The Cisco Nexus 2248TP , Cisco Nexus 2232PP , and Cisco Nexus 2224PP support EtherChannel host interface configurations. Up to eight interfaces can be combined in an EtherChannel . The EtherChannel can be configured with or without LACP.

    Note

    Support for EtherChannel host interface configuration was added to the Fabric Extender from Cisco NX-OS Release 4.2(1)N1(1).

    For more information about EtherChannels , see the Cisco Nexus 5000 Series NX-OS Layer 2 Switching Configuration Guide .

    VLANs and Private VLANs

    • You can configure a host interface as an isolated or community access port only.
    • You cannot configure a host interface as a promiscuous port.
    • You cannot configure a host interface as a private VLAN trunk port.

    Virtual Port Channels

      The parent switches are connected single homed to Fabric Extender s which are subsequently connected to servers with dual interfaces (see the following figure).

    Figure 2. Single Homed Fabric Extender vPC Topology

    Host Interface vPC Topology

    Figure 3. Dual Homed Fabric Extender vPC Topology

    Fabric Extender vPC Topology

    Fibre Channel over Ethernet Support

    • Only FCoE Initialization Protocol (FIP) enabled converged network adapters (CNAs) are supported on the Fabric Extender .
    • Binding to an EtherChannel is limited to only one member EtherChannel .

    Protocol Offload

    • Link Layer Discovery Protocol (LLDP) and Data Center Bridging Exchange (DCBX)
    • Cisco Discovery Protocol (CDP)
    • Link Aggregation Control Protocol (LACP)

    Quality of Service

    The Fabric Extender provides two user queues for its quality-of-service (QoS) support, one for all no-drop classes and one for all drop classes. The classes configured on its parent switch are mapped to one of these two queues; traffic for no-drop classes is mapped to one queue and traffic for all drop classes is mapped to the other. Egress policies are also restricted to these two classes.

    The parent switch provides two predefined type qos class maps for matching broadcast or multicast traffic; class-all-flood and class-ip-multicast. These classes are ignored on the Fabric Extender .

    The Fabric Extender uses IEEE 802.1p class of service (CoS) values to associate traffic with the appropriate class. Per-port QoS configuration and CoS-based egress queuing is also supported.

    Host interfaces support pause frames, which are implemented using IEEE 802.3x link-level flow control (LLC). By default, flow control send is on and flow control receive is off on all host interfaces. Autonegotiation is enabled on the host interfaces. Per-class flow control is set according to the QoS classes.

    Host interfaces support jumbo frames (up to 9216 bytes); however, a per-host interface maximum transmission unit (MTU) is not supported. Instead, MTU is set according to the QoS classes. You modify MTU by setting policy and class maps on the parent switch. Because the Fabric Extender has only two user queues, the MTU for the drop-queue is set to the maximum MTU of all drop classes and the MTU on the no-drop queue is set to the maximum MTU of all no-drop classes.

    For more information about LLC and quality-of-service, see the Cisco Nexus 5000 Series NX-OS Quality of Service Configuration Guide .

    Access Control Lists

    The Cisco Nexus 2000 Series Fabric Extender supports the full range of ingress access control lists (ACLs) that are available on its parent switch.

    IGMP Snooping

    IGMP snooping is supported on all host interfaces of the Fabric Extender .

    The Fabric Extender and its parent switch support IGMPv3 snooping based only on the destination multicast MAC address. It does not support snooping based on the source MAC address or on proxy reports.

    Note

    For more information about IGMP snooping, see http://tools.ietf.org/wg/magma/draft-ietf-magma-snoop/rfc4541.txt. Also, see the Cisco Nexus 5000 Series NX-OS Layer 2 Switching Configuration Guide Cisco Nexus 7000 Series NX-OS Multicast Routing Configuration Guide, Release 5.x .

    Switched Port Analyzer

    You can configure the host interfaces on the Fabric Extender as Switched Port Analyzer (SPAN) source ports. Fabric Extender ports cannot be configured as a SPAN destination. Only one SPAN session is supported for all the host interfaces on the same Fabric Extender . Ingress source (Rx), egress source (Tx), or both ingress and egress monitoring are supported.

    Note

    All IP multicast traffic on the set of VLANs that a Fabric Extender host interface belongs to is captured in the SPAN session. You cannot separate the traffic by IP multicast group membership.

    If ingress monitoring and egress monitoring is configured for host interfaces on the same Fabric Extender , you might see a packet twice: once as the packet ingresses on an interface with Rx configured, and again as the packet egresses on an interface with Tx configured.

    For more information about SPAN, see the Cisco Nexus 7000 Series NX-OS System Management Configuration Guide, Release 5.x

    Fabric Interface Features

    • The FEX performs a local check on the uplink SFP+ transceiver. If it fails the security check, the LED flashes but the link is still allowed to come up.
    • The FEX local check is bypassed if it is running its backup image.
    • The parent switch performs SFP validation again when the fabric interface is brought up. It keeps the fabric interface down if SFP validation fails.
    Note

    Per class flow control mode is enabled by default on the fabric interfaces. When a fabric interface is configured on the parent switch, PFC mode is enabled by default and cannot be changed.

    For more information about PFC, see the Cisco Nexus 5000 Series NX-OS Quality of Service Configuration Guide

    Oversubscription

    • No oversubscription (40 host interfaces for four fabric interfaces)
    • 1.2 to 1 oversubscription (48 host interfaces for four fabric interfaces)
    • 4.8 to 1 oversubscription (48 host interfaces for one fabric interface)

    Management Model

    1. The switch checks the software image compatibility and upgrades the Fabric Extender if necessary.
    2. The switch and Fabric Extender establish in-band IP connectivity with each other. The switch assigns an IP address in the range of loopback addresses (127.15.1.0/24) to the Fabric Extender to avoid conflicts with IP addresses that might be in use on the network.
    3. The switch pushes the configuration data to the Fabric Extender . The Fabric Extender does not store any configuration locally.
    4. The Fabric Extender updates the switch with its operational status. All Fabric Extender information is displayed using the switch commands for monitoring and troubleshooting.
    Note

    Prior to Cisco NX-OS Release 4.1(3)N1(1), a Cisco Nexus 2000 Series Fabric Extender could be managed by one parent switch only.

    Forwarding Model

    The Cisco Nexus 2000 Series Fabric Extender does not perform any local switching. All traffic is sent to the parent switch that provides central forwarding and policy enforcement, including host-to-host communications between two systems that are connected to the same Fabric Extender as shown in the following figure.

    Figure 4. Forwarding Model

    Traffic between two hosts connected to the Fabric Extender is forwarded through the parent switch.

    The forwarding model facilitates feature consistency between the Fabric Extender and its parent Cisco Nexus 5000 Series device.

    Note

    The Fabric Extender provides end-host connectivity into the network fabric. As a result, BPDU Guard is enabled on all its host interfaces. If you connect a bridge or switch to a host interface, that interface is placed in an error-disabled state when a BPDU is received.

    You cannot disable BPDU Guard on the host interfaces of the Fabric Extender .

    The Fabric Extender supports egress multicast replication from the network to the host. Packets sent from the parent switch for multicast addresses attached to the Fabric Extender are replicated by the Fabric Extender ASICs and then sent to corresponding hosts.

    Connection Model

    Two methods (the static pinning fabric interface connection and the EtherChannel fabric interface connection) allow the traffic from an end host to the parent switch to be distributed when going through the Cisco Nexus 2000 Series Fabric Extender .

    • Static Pinning Fabric Interface Connection
    • Port Channel Fabric Interface Connection

    Static Pinning Fabric Interface Connection

    To provide a deterministic relationship between the host interfaces and the parent switch, you can configure the Fabric Extender to use individual fabric interface connections. This configuration connects the 10-Gigabit Ethernet fabric interfaces as shown in the following figure. You can use any number of fabric interfaces up to the maximum available on the model of the Fabric Extender .

    Figure 5. Static Pinning Fabric Interface Connections

    Individual fabric interfaces are statically pinned between a Fabric Extender and its parent switch.

    When the Fabric Extender is brought up, its host interfaces are distributed equally among the available fabric interfaces. As a result, the bandwidth that is dedicated to each end host toward the parent switch is never changed by the switch but instead is always specified by you.

    Note

    If a fabric interface fails, all its associated host interfaces are brought down and remain down until the fabric interface is restored.

    You must use the pinning max-links command to create a number of pinned fabric interface connections so that the parent switch can determine a distribution of host interfaces. The host interfaces are divided by the number of the max-links and distributed accordingly. The default value is max-links 1.

    Caution

    Changing the value of the max-links is disruptive; all the host interfaces on the Fabric Extender are brought down and back up as the parent switch reassigns its static pinning.

    The pinning order of the host interfaces is initially determined by the order in which the fabric interfaces were configured. When the parent switch is restarted, the configured fabric interfaces are pinned to the host interfaces in an ascending order by the port number of the fabric interface.

    To guarantee a deterministic and sticky association across a reboot, you can manually redistribute the pinning.

    Note

    The redistribution of the host interfaces will always be in an ascending order by the port number of the fabric interface.

    Port Channel Fabric Interface Connection

    To provide load balancing between the host interfaces and the parent switch, you can configure the Fabric Extender to use a port channel fabric interface connection. This connection bundles 10-Gigabit Ethernet fabric interfaces into a single logical channel as shown in the following figure.

    Figure 6. Port Channel Fabric Interface Connection

    An EtherChannel fabric interface bundles connections into a single logical channel.

    • For a Layer 2 frame, the switch uses the source and destination MAC addresses.
    • For a Layer 3 frame, the switch uses the source and destination MAC addresses and the source and destination IP addresses.
    Note

    A fabric interface that fails in the port channel does not trigger a change to the host interfaces. Traffic is automatically redistributed across the remaining links in the port channel fabric interface. If all links in the fabric port channel go down, all host interfaces on the FEX are set to the down state.

    Port Numbering Convention

      chassis is configured by the administrator. A Fabric Extender must be directly connected to its parent Cisco Nexus 5000 Series device via individual fabric interfaces or a port channel fabric interface. You configure a chassis ID on a physical Ethernet interface or port channel on the switch to identify the Fabric Extender that is discovered through those interfaces. The chassis ID ranges from 100 to 199.
    Note The chassis ID is required only to access a host interface on the Fabric Extender . A value of less than 100 indicates a slot on the parent switch. The following port numbering convention is used for the interfaces on the switch: interface ethernet slot / port

    Fabric Extender Image Management

    No software ships with the Cisco Nexus 2000 Series Fabric Extender . The Fabric Extender image is bundled into the system image of the parent switch. The image is automatically verified and updated (if required) during the association process between the parent switch and the Fabric Extender .

    When you enter the install all command, it upgrades the software on the parent Cisco Nexus 5000 Series switch and also upgrades the software on any attached Fabric Extender . To minimize downtime as much as possible, the Fabric Extender remains online while the installation process loads its new software image. Once the software image has successfully loaded, the parent switch and the Fabric Extender both automatically reboot.

    This process is required to maintain version compatibility between the parent switch and the Fabric Extender .

    Fabric Extender Hardware

    The Cisco Nexus 2000 Series Fabric Extender architecture allows hardware configurations with various host interface counts and speeds.

    Chassis

    The Cisco Nexus 2000 Series Fabric Extender is a 1 RU chassis that is designed for rack mounting. The chassis supports redundant hot-swappable fans and power supplies.

    Ethernet Interfaces

    • The Cisco Nexus 2148T has 48 1000BASE-T Ethernet host interfaces for its downlink connection to servers or hosts and 4 10-Gigabit Ethernet fabric interfaces with SFP+ interface adapters for its uplink connection to the parent switch.
    • The Cisco Nexus 2224PP has 24 100BASE-T/1000Base-T Ethernet host interfaces for its downlink connection to servers or hosts and 2 10-Gigabit Ethernet fabric interfaces with SFP+ interface adapters for its uplink connection to the parent switch.
    • The Cisco Nexus 2232PP has 32 10-Gigabit Ethernet host interfaces with SFP+ interface adapters and 8 10-Gigabit Ethernet fabric interfaces with SFP+ interface adapters for its uplink connection to the parent switch.
    • The Cisco Nexus 2248TP has 48 100BASE-T/1000Base-T Ethernet host interfaces for its downlink connection to servers or hosts and 4 10-Gigabit Ethernet fabric interfaces with SFP+ interface adapters for its uplink connection to the parent switch.

    Information About Associating a Fabric Extender to a Fabric Interface

    A Cisco Nexus 2000 Series Fabric Extender is connected to its parent device through physical Ethernet interfaces or a port channel. By default, the parent device does not allow the attached Fabric Extender to connect until it has been assigned a FEX-number and is associated with the connected interface.

    Note

    The Fabric Extender may connect to the switch through a number of separate physical Ethernet interfaces or one port channel interface.

    Caution

    Prior to Cisco NX-OS Release 4.1(3)N1(1), you could not connect the Ethernet interfaces of the Expansion Modules in the Cisco Nexus 5000 Series switch to a Fabric Extender .

    Note

    You must enable the Fabric Extender features with the feature fex command before you can configure and use a Fabric Extender that is connected to the parent switch. Prior to Release 4.1(3)N2(1), this functionality was enabled by default.

    Redistributing the Links

    • A change in the max-links configuration.
    • If you need to maintain the pinning order of host interfaces to fabric interfaces.
    • Changing the Number of Links
    • Maintaining the Pinning Order

    Changing the Number of Links

    If you initially configured a specific port on the parent switch, for example port 33, as your only fabric interface, all 48 host interfaces are pinned to this port. If you provision another port, for example 35, then you must enter the pinning max-links 2 command to redistribute the host interfaces. All host interfaces are brought down and host interfaces 1 to 24 are pinned to fabric interface 33 and host interfaces 25 to 48 are pinned to fabric interface 35.

    Maintaining the Pinning Order

    The pinning order of the host interfaces is initially determined by the order in which the fabric interfaces were configured. In this example, four fabric interfaces were configured in the following order:

    switch# show interface ethernet 1/35 fex-intf Fabric FEX Interface Interfaces --------------------------------------------------- Eth1/35 Eth101/1/12 Eth101/1/11 Eth101/1/10 Eth101/1/9 Eth101/1/8 Eth101/1/7 Eth101/1/6 Eth101/1/5 Eth101/1/4 Eth101/1/3 Eth101/1/2 Eth101/1/1 switch# show interface ethernet 1/33 fex-intf Fabric FEX Interface Interfaces --------------------------------------------------- Eth1/33 Eth101/1/24 Eth101/1/23 Eth101/1/22 Eth101/1/21 Eth101/1/20 Eth101/1/19 Eth101/1/18 Eth101/1/17 Eth101/1/16 Eth101/1/15 Eth101/1/14 Eth101/1/13 switch# show interface ethernet 1/38 fex-intf Fabric FEX Interface Interfaces --------------------------------------------------- Eth1/38 Eth101/1/36 Eth101/1/35 Eth101/1/34 Eth101/1/33 Eth101/1/32 Eth101/1/31 Eth101/1/30 Eth101/1/29 Eth101/1/28 Eth101/1/27 Eth101/1/26 Eth101/1/25 switch# show interface ethernet 1/40 fex-intf Fabric FEX Interface Interfaces --------------------------------------------------- Eth1/40 Eth101/1/48 Eth101/1/47 Eth101/1/46 Eth101/1/45 Eth101/1/44 Eth101/1/43 Eth101/1/42 Eth101/1/41 Eth101/1/40 Eth101/1/39 Eth101/1/38 Eth101/1/37

    The next time that you reboot the Fabric Extender , the configured fabric interfaces are pinned to the host interfaces in an ascending order by port number of the fabric interface. If you want to configure the same fixed distribution of host interfaces without restarting the Fabric Extender , enter the fex pinning redistribute command.

    Redistributing Host Interfaces

    You can redistribute the host interfaces on the Fabric Extender . Enter the fex pinning redistribute FEX-number command to redistribute the host connections. The range of the FEX-number is from 100 to 199.

    This example shows how to redistribute the host interfaces on a Fabric Extender :

    switch# fex pinning redistribute 101 
    Caution

    The fex pinning redistribute command disrupts all the host interface ports of the Fabric Extender .

    Verifying the Fabric Extender Configuration

    To display configuration information about the defined interfaces on a Fabric Extender , perform one of the following tasks:

    Command or Action

    Purpose
