Description
Specify that the jdhcpd process keeps
the incoming circuit ID and prepends the ID with the locally generated
ID (in the format, generated-id + incoming-id) before sending
the leasequery packet to the DHCP server.
This configuration is required for leasequery and bulk leasequery operations when subscriber authentication is based on the circuit ID, and enables leasequery and bulk leasequery to restore the agent circuit identifier/agent remote identifier (ACI/ARI) pair and to use the circuit ID to authenticate subscribers.
