Configuring a VSS
Backing Up the Standalone Configuration
Save the configuration files for both switches operating in standalone mode. You need these files to
revert to standalone mode from virtual switch mode.
On Switch 1, perform this task:
Command
Step 1
Switch-1# copy running-config startup-config
Step 2
Switch-1# copy startup-config
disk0:old-startup-config
On Switch 2, perform this task:
Command
Step 1
Switch-2# copy running-config startup-config
Step 2
Switch-2# copy startup-config
disk0:old-startup-config
Configuring SSO and NSF
SSO and NSF are configured as default on VSS.
Assigning Virtual Switch Domain and Switch Numbers
You must configure the same virtual switch domain number on both switches of the VSS. The virtual
switch domain is a number between 1 and 255, and must be unique for each VSS in your network (the
domain number is incorporated into various identifiers to ensure that these identifiers are unique across
the network).
Within the VSS, you must configure one switch to be switch number 1 and the other switch to be switch
number 2.
To configure the virtual switch domain and switch number on both switches, perform this task on
Switch 1:
Command
Step 1
Switch-1(config)# switch virtual domain 100
Step 2
Switch-1(config-vs-domain)# switch 1
Step 3
Switch-1(config-vs-domain)# exit
