None
Enabled
Global configuration
When this check for the reply packet is enabled, the device will check that the
option-82 field in DHCP reply packets it receives from the DHCP server is valid. If
an invalid message is received, the relay agent drops it. If a valid message is
received, the relay agent removes the option-82 field and forwards the packet.
If the check is disabled, a packet with an invalid option-82 field will be directly
forwarded.
Enabled DHCP relay agent check for the reply packet.
Verify the settings by entering the show ip dhcp relay command.
