sub-slot number, interface number, and VLAN ID. The node identifier varies with the keyword mac,
sysname, and user-defined.
• mac: Uses the MAC address of the access node as the node identifier. It is the default node
identifier.
• sysname: Uses the device name as the node identifier. You can set the device name by using the
sysname command in system view. The padding format for the device name is always ASCII
regardless of the specified padding format.
• user-defined node-identifier: Uses a case-sensitive string of 1 to 50 characters as the node identifier.
The padding format for the specified character string is always ASCII regardless of the specified
padding format.
format: Specifies the code type for the circuit ID sub-option.
ascii: Specifies the ASCII code type.
hex: Specifies the hex code type.
