Configuring the Fabric Extender

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
Interface
---------------------------------------------------
Eth1/35
switch# show interface ethernet 1/33 fex-intf
Fabric
Interface
---------------------------------------------------
Eth1/33
switch# show interface ethernet 1/38 fex-intf
Fabric
Interface
---------------------------------------------------
Eth1/38
switch# show interface ethernet 1/40 fex-intf
Fabric
Interface
---------------------------------------------------
Eth1/40
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
The fex pinning redistribute command disrupts all the host interface ports of the Fabric Extender.
