Description
Use this command to set the response of the DHCP relay agent to client
packets containing option-82 information. This command has to be used in
combination with “IP DHCP-RELAY AGENT-OPTION” on page 496.
If you select the append policy, the relay agent overwrites any pad options
present in the packets before appending its option 82 data and, if
necessary, increases the packet length to accommodate the option 82
data.
To return the policy to the default replace policy, use the NO form of this
command.
