Changing the DHCPv4 remote-id from a MAC to an IP address

By default, DHCPv4 snooping uses the MAC address of the switch as the remoteid in Option 82 additions. The IP address of the VLAN the packet was received on or the IP address of the management VLAN can be used instead by entering this command with the associated parameter:
switch(config)# dhcp-snooping option 82 remote-id <mac|subnet-ip|mgmt-ip>
