Configuring a VSS
VSL Status : UP
VSL Uptime : 13 minutes
VSL Control Link : Te2/1/1
Converting a VSS to Standalone Switch
To convert a VSS into two standalone systems, you perform the following major steps:
•
Copying the VSS Configuration to a Backup File, page 5-41
• Converting the VSS Active Switch to Standalone, page 5-41
•
Converting the VSS Standby Switch to Standalone, page 5-42
Copying the VSS Configuration to a Backup File
Save the configuration file from the VSS Active switch. You may need this file if you convert to virtual
switch mode again. You only need to save the file from the VSS Active switch, because the configuration
file on the VSS Standby switch is identical to the file on the VSS Active switch.
Converting the VSS Active Switch to Standalone
When you convert the VSS Active switch to standalone mode, the VSS Active switch removes the
provisioning and configuration information related to VSL links and the peer chassis modules, saves the
configuration file, and performs a reload. The switch comes up in standalone mode with only the
configuration data relevant to the standalone system.
The VSS Standby switch of the VSS becomes VSS Active. VSL links on this switch are down because
the peer is now unavailable.
To convert the VSS Active switch to standalone mode, perform this task on the VSS Active switch:
Conversion from VSS to standalone causes all physical interfaces to be administratively shutdown and
written to the startup-config. This is a safeguard against a standalone system arriving in the network alive
and conflicting with a bridge or router MAC address, which might still be there if one of the VSS
switches is still running in VSS mode.
Command Purpose
Step 1
Switch-1# copy running-config startup-config
(Optional) Saves the running configuration to startup
configuration. This step is only required if there are
unsaved changes in the running configuration that
you want to preserve.
Step 2
Switch-1# copy startup-config
bootflash:vs-startup-config
Copies the startup configuration to a backup file.
Command Purpose
Switch-1# switch convert mode stand-alone
Converts Switch 1 to standalone mode.
