DHCP Option 82: Using the Management VLAN IP Address for the Remote ID
This section describes the Management VLAN enhancement to the DHCP option 82 feature. For more
information on DHCP option 82 operation, refer to “Configuring DHCP Relay” in the chapter titled
“IP Routing Features” in the
Advanced Traffic Management Guide
for your switch.
When the routing switch is used as a DHCP relay agent with Option 82 enabled, it inserts a relay agent
information option into client-originated DHCP packets being forwarded to a DHCP server. The
option automatically includes two suboptions:
■
Circuit ID: the identity of the port through which the DHCP request entered the relay agent
■
Remote ID: the identity (IP address) of the DHCP relay agent
Using earlier software releases, the remote ID can be either the routing switch’s MAC address (the
default option) or the IP address of the VLAN or subnet on which the client DHCP request was
received. Beginning with software release L.10.04, if a Management VLAN is configured on the routing
switch, then the Management VLAN IP address can be used as the remote ID.
