DHCP Relay Option 61 Settings
This command is used to add a rule to the relay server based on option 61. The matching rule can be based on either
the MAC address or the user-specified string. Only one relay server can be specified for a MAC-address or a string.
Both option 60 and option 61 can be assigned to a specific DHCP server based on whether they match the
configuration in the DHCP packet. If several relay servers are determined by option 60, and one relay server is
determined by option 61, the final relay servers will be determined by both option 60 and 61.
