R21xx-HP FlexFabric 11900 Layer 3 IP Services Command Reference

88
normal: Specifies the normal padding format. The padding content includes the VLAN ID and interfce
number.
verbose: Specifies the verbose padding format.
node-identifier { mac | sysname | user-defined node-identifier }: Specifies the access node identifier. By
default, the node MAC address is used as the node identifier. The padding content includes the node
identifier, Ethernet type (fixed to eth), chassis number, slot number, sub-slot number, interface number,
and VLAN ID. The node identifier varies with the keyword mac, sysname, and user-defined.
• mac: Uses the node MAC address as the node identifier.
• sysname: Uses the system name as the node identifier. The system name can be configured with the
sysname command in system view. The padding format for the system name is always ASCII
regardless of the specified padding format.
• user-defined node-identifier: Specifies a node identifier, a case-sensitive string of 1 to 50 characters.
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.

If replace is configured as the handling strategy for DHCP requests containing Option 82, you need to
configure the padding content and code type for the circuit ID sub-option. If the handling strategy is keep
or drop, you do not need to configure the padding content and code type for the circuit ID sub-option.
