Configuring the Fabric Extender

This chapter describes how to configure a Cisco Nexus 2000 Series Fabric Extender with a Cisco Nexus 5000 Series switch and includes the following sections:

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

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

 

Command
Purpose

Step 1

switch# configure terminal

Enters configuration mode.

Step 2

switch(config)# interface ethernet slot / port

Specifies an Ethernet interface to configure.

Step 3

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

Sets the interface to support an external Fabric Extender.

Step 4

switch(config-if)# fex associate chassis

Disassociating a Fabric Extender from an Interface

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

 

Command
Purpose

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:

 

Command
Purpose

Step 1

switch# configure terminal

Enters configuration mode.

Step 2

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.

Step 3

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.

switch(config-fex)# beacon

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
---------------------------------------------------
Eth1/35 Eth100/1/12 Eth100/1/11 Eth100/1/10 Eth100/1/9
Eth100/1/8 Eth100/1/7 Eth100/1/6 Eth100/1/5
Eth100/1/4 Eth100/1/3 Eth100/1/2 Eth100/1/1

Eth100/1/16 Eth100/1/15 Eth100/1/14 Eth100/1/13

Eth1/38 Eth100/1/36 Eth100/1/35 Eth100/1/34 Eth100/1/33
Eth100/1/32 Eth100/1/31 Eth100/1/30 Eth100/1/29
Eth100/1/28 Eth100/1/27 Eth100/1/26 Eth100/1/25

switch# show interface ethernet 1/40 fex-intf

---------------------------------------------------
Eth1/40 Eth100/1/48 Eth100/1/47 Eth100/1/46 Eth100/1/45
Eth100/1/44 Eth100/1/43 Eth100/1/42 Eth100/1/41
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:

 

Command
Purpose

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
