ip dhcp relay information
The ip dhcp relay information command enable the DHCP relay agent to insert
DHCP option 82, sub-options into DHCP requests. Support for DHCP Option-82,
sub-option 2 (Agent Remote ID), which is enabled by the ip dhcp relay information
option command, allows the relay agent in the BSR to insert just the DHCP client’s
MAC address into outbound DHCP client requests (i.e., DHCP Discovers and DHCP
Requests as they traverse the BSR). Support for DHCP Option-82, sub-option 4
(DOCSIS Device Class Identifier), which is enabled by the
ip dhcp relay
information option
command, allows the relay agent in the BSR to insert the
DOCSIS Device Class Identifier into outbound client DHCP Discovers. Support for
DHCP Option-82, sub-option 85 (Spectrum Group Name), which is enabled by the ip
dhcp relay information spectrum-group-name command, allows the relay agent in
the BSR to insert, when available, the Spectrum Group name associated with the
upstream channel that the DHCP client is using into outbound DHCP client requests
(i.e., DHCP Discovers and DHCP Requests as they traverse the BSR).
