S Commands


This chapter describes the Cisco NX-OS commands that begin with S that are used to manage a Cisco Nexus 2000 Series Fabric Extender from a Cisco Nexus 6000 switch.

serial

To assign a serial number to a Fabric Extender, use the serial command. To remove the serial number, use the no form of this command.

serial serial_string

no serial

Syntax Description

serial_string

Serial number string for the Fabric Extender. The string is alphanumeric, case sensitive, and has a maximum length of 20 characters.


Command Default

None

Command Modes

Fabric extender configuration mode

Command History

Release
Modification

6.0(2)N1(1)

This command was introduced.


Usage Guidelines

The serial number string 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 will succeed only if the Fabric Extender reports a matching serial number string.


Caution Configuring a serial number other than that of the given Fabric Extender will force 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
switch(config-fex)# no serial

Examples

This example shows how to enable a chassis slot for preprovisioning of a module:

switch(config)# slot 2
switch(config-slot)#
 
   

This example shows how to disable a chassis slot for preprovisioning of a module:

switch(config)# no slot 2
switch(config)#
