When the option-82 feature is enabled, the default circuit-ID suboption is the
switch VLAN and port identifier in the format of vlan-mod-port. This command
allows you to configure a string of ASCII characters to be the circuit ID. When you
want to override the vlan-mod-port format type and use the circuit ID to define the
subscriber information, use the override keyword.
