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.
