your reseller or Foundry Networks for information.
USING THE CLI
To globally disable Layer 2 switching on a Layer 3 Switch, enter commands such as the following:
BigIron(config)# route-only
BigIron(config)# exit
BigIron# write memory
BigIron# reload
To re-enable Layer 2 switching on a Layer 3 Switch, enter the following:
BigIron(config)# no route-only
BigIron(config)# exit
BigIron# write memory
BigIron# reload
Syntax: [no] route-only
To disable Layer 2 switching only on a specific interface, go to the Interface configuration level for that interface,
then disable the feature. The following commands show how to disable Layer 2 switching on port 3/2:
BigIron(config)# interface ethernet 3/2
BigIron(config-if-3/2)# route-only
Syntax: [no] route-only
To re-enable Layer 2 switching, enter the command with "no", as in the following example:
BigIron(config-if-3/2)# no route-only
