(Optional) Configuring VSS Standby Switch Modules

You cannot configure or provision modules on VSS.
Note
When switches form initial VSS relationships, they send module information to each other and this
information is pushed to the configuration and used subsequently for provisioning, provided the switch
is booting and the peer is down or not present.
The following example shows the module provisioning information:
module provision switch 1
slot 1 slot-type 148 port-type 60 number 4
slot 2 slot-type 137 port-type 31 number 16
slot 3 slot-type 227 port-type 60 number 8
slot 4 slot-type 225 port-type 61 number 48
slot 5 slot-type 82 port-type 31 number 2
module provision switch 2
slot 1 slot-type 148 port-type 60 number 4
slot 2 slot-type 227 port-type 60 number 8
slot 3 slot-type 137 port-type 31 number 16
slot 4 slot-type 225 port-type 61 number 48
slot 5 slot-type 82 port-type 31 number 2
These commands are not available to the user and that various numbers used in these commands are
internal to the system and used to identify a module. These commands are written to the startup-config
when a switch detects a given module while it is running in VSS mode. When reconverted to standalone
mode, these commands are removed from the startup-config.
Displaying VSS Information
To display basic information about the VSS, perform one of these tasks:
Command
Switch# show switch virtual
Switch# show switch virtual role
Switch# show switch virtual link
The following example shows the information output from these commands:
Switch# show switch virtual
Executing the command on VSS member switch role = VSS Active, id = 1
Switch mode
Virtual switch domain number : 100
Local switch number
Local switch operational role: Virtual Switch Active
Peer switch number
Peer switch operational role : Virtual Switch Standby
Executing the command on VSS member switch role = VSS Standby, id = 2
Switch mode
