By default, the remote ID sub-option in Option 82 is the MAC address of the DHCP Snooping device
that received the DHCP client's request.
If you have configured a remote ID with the vlan vlan-id argument specified, and the other one without
the argument in Ethernet port view, the former remote ID applies to the DHCP messages from the
specified VLAN, while the latter one applies to DHCP messages from other VLANs.
