Usage Guidelines

The serial number string that you define with the serial command must match the serial number of the Fabric Extender. If you configure a serial number and then you use the fex associate command to associate the corresponding chassis ID to the switch, the association succeeds only if the Fabric Extender reports a matching serial number string.

Caution Configuring a serial number other than that of the given Fabric Extender forces the Fabric Extender offline.

Examples

This example shows how to specify a serial number for a Fabric Extender:

switch# configure terminal
switch(config)# fex 101
switch(config-fex)# serial Rack16_FEX101
 

This example shows how to remove a serial number from a Fabric Extender:

switch# configure terminal
switch(config)# fex 101
