What is rlIpDhcpOpt82InsertionEnable?
This read-write INTEGER (enable(1)/disable(2)) turns on insertion of DHCP option 82 (relay agent information) into client DHCP requests as they pass through the switch. An admin cares because option 82 lets an upstream DHCP server identify which switch port a request originated from, enabling per-port IP address policies. For example, an admin using a centralized DHCP server that assigns addresses based on the requesting switch port would enable this so option 82 data is inserted for the server to use.
