Use this command to assign a subscriber ID to a port. By default, no
subscriber IDs are assigned to any port on the switch.
The subscriber ID sub-option is included in the DHCP Option 82 field of
client DHCP packets that are forwarded from a port if all the following
conditions are met:
A subscriber ID is specified for the port using the IP DHCP
SNOOPING SUBSCRIBER-ID command.
DHCP Snooping Option 82 is enabled using “IP DHCP
SNOOPING AGENT-OPTION” on page 627. This command is
enabled by default.
DHCP Snooping is enabled on the switch with the SERVICE
DHCP SNOOPING command and on the VLAN to which the port
belongs using “IP DHCP SNOOPING” on page 626.
Use the no version of the command, NO IP DHCP SNOOPING
SUBSCRIBER-ID command, to remove the subscriber id assigned to a
port.
