Description
Select the slot/port to configure this feature on.
Enable or disable L2 Relay mode on the selected interface.
Enable or disable L2 Relay Trust Mode on the selected interface.
Trusted interfaces usually connect to other agents or servers
participating in the DHCP interaction (e.g. other L2 or L3 Relay Agents
or Servers). When enabled in Trust Mode, the interface always expects
to receive DHCP packets that include Option 82 information. If Option 82
information is not included, then these packets are discarded.
Untrusted interfaces are generally connected to clients. DHCP packets
arriving on an untrusted interface are never expected to carry Option 82
and are discarded if they do.
