Default command level
2: System level
Parameters
vlan vlan-id: Specifies a VLAN ID in the range of 1 to 4094.
circuit-id: Padding content for the user-defined circuit ID sub-option, a case-sensitive string of 3 to 63
characters.
Usage guidelines
After you configure the padding content for the circuit ID sub-option using this command, ASCII is
adopted as the code type.
If a VLAN is specified, the configured circuit ID sub-option only takes effect within the VLAN. If no VLAN
is specified, the configured circuit ID sub-option takes effect in all VLANs. The circuit ID sub-option
specified for a VLAN is padded for packets within the VLAN.
