Virtual LAN Routing Commands
This section describes the commands you use to view and configure VLAN routing and to
view VLAN routing status information.
vlan routing
This command enables routing on a VLAN. The vlanid value has a range from 1 to 4093. The
[interface ID] value has a range from 1 to 128. Typically, you will not supply the interface ID
argument, and the system automatically selects the interface ID. However, if you specify an
interface ID that is already in use, the CLI displays an error message and does not create the
VLAN interface.
