UDP Relay and Group Mobility
If UDP Relay is being used with a Mobile DHCP Rule, determine if the end station is simply getting the
wrong IP address scope. If this is the case, verify group mobility, as the source VLAN of the UDP request
could be wrong when it reaches the UDP Relay function.
If no address is received and AVLAN forwarding is being used, again check group mobility and verify the
UDP request is being classified into the correct VLAN. This can be done by using the show mac-address-
table CLI command.
Take a trace both on the client connection as well as on the server connection can often be helpful to illu-
minate configuration errors.
