Chapter 5 Configuring Virtual Switching Systems
Configuring a VSS
On Switch 2, perform this task:
Note 1G ports, which are converted from 10G ports using a connector, are not supported for VSL. This
impacts Sup7-E and Sup7L-E ports.
Converting the Switch to Virtual Switch Mode
Conversion to virtual switch mode requires a restart for both switches. After the reboot, commands that
specify interfaces with module/port now include the switch number. For example, a port on a switching
module is specified by switch/module/port.
Prior to the restart, the VSS converts the startup configuration to use the switch/module/port convention.
A backup copy of the startup configuration file is saved in bootflash. This file is assigned a default name,
but you are also prompted to override the default name if you want to change it.
To convert Switch 1 to virtual switch mode, perform this task:
To convert Switch 2 to virtual switch mode, perform this task on Switch 2:
Command Purpose
Step 1
Switch-2(config)# interface range
tengigabitethernet 5/2-3
Enters configuration mode for interface range
tengigabitethernet 5/2-3 on Switch 2.
Step 2
Switch-2(config-if)# channel-group 20 mode on
Adds this interface to channel group 20.
Command Purpose
Switch-1# switch convert mode virtual
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 of the VSS active
supervisor. In Quad-Supervisor VSS mode, the con-
figuration files must be copied from the active super-
visor to the in-chassis standby supervisor, using the
copy bootflash: <image_name> slavebootflash-
ics: <image_name>
command.
Command Purpose
Switch-2# switch convert mode virtual
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.
