Optional) Configuring Vss Standby Switch Modules - Cisco Catalyst 4500 series Administration Manual

Chapter 5 Configuring Virtual Switching Systems
To convert Switch 1 to virtual switch mode, perform this task:
Command
Switch-1# switch convert mode virtual
To convert Switch 2 to virtual switch mode, perform this task on Switch 2:
Command
Switch-2# switch convert mode virtual
After you confirm the command (by entering yes at the prompt), the running configuration is
Note
automatically saved as the startup configuration and the switch reboots. After the reboot, the switch is
in virtual switch mode, so you must specify interfaces with three identifiers (switch/module/port).
When switches are being converted to VSS, you should not set them to ignore startup-config. If done,
the switch can be enabled to parse the startup-config at the rommon prompt. Ignoring startup-config in
VSS mode, causes a switch to boot in a semi-VSS mode, which can only be corrected by a reboot and
by enabling the parsing of startup-config.

(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

Purpose
Converts Switch 1 to virtual switch mode.
After you enter the command, you are prompted to
confirm the action. Enter yes.
The system creates a converted configuration file, and
saves the file to the bootflash.
Purpose
Converts Switch 2 to virtual switch mode.
After you enter the command, you are prompted to
confirm the action. Enter yes.
The system creates a converted configuration file, and
saves the file to the bootflash.
