Chapter 5 Configuring Virtual Switching Systems
Configuring a VSS
In the procedures that follow, the example commands assume the configuration shown in Figure 5-8.
Figure 5-8 Example VSS
Two chassis, A and B, are converted into a VSS with virtual switch domain 100. Interface 10-Gigabit
Ethernet 5/1 on Switch 1 is connected to interface 10-Gigabit Ethernet 5/2 on Switch 2 to form the VSL.
Note The port channels 10 and 20 mentioned in the config steps below are merely exemplary. You can
configure any port channel number from 1-64 for VSL port channel.
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.
Perform this task on both switches:
181325
Virtual switch link
(VSL)
Chassis A
(Switch 1)
Chassis B
(Switch 2)
T 5/1 T 5/2
Command Purpose
Step 1
Switch-1# copy running-config startup-config
(Optional) Saves the running configuration to startup
configuration.
Step 2
Switch-1# copy startup-config
bootflash:old-startup-config
Or
Switch-1# copy startup-config
slot0:old-startup-config
Copies the startup configuration to a backup file.
Step 3
Switch-1# copy startup-config
slavebootflash:old-startup-config
Or
Switch-1# copy startup-config
slaveslot0:old-startup-config
Note This step is required for switches in
Quad-Supervisor VSS mode only.
Copies the startup configuration to the standby
supervisors.
