Usage
Information
If you configure the
ip helper-address
command and
ip udp-helper udp-
port
command, the behavior is that the UDP broadcast traffic with port numbers
67/68 is unicast relayed to the DHCP server per the
ip helper-address
configuration. This occurs regardless if the
ip udp-helper udp-port
command
contains port numbers 67/68 or not.
If you only configure the
ip udp-helper udp-port
command, all the UDP
broadcast traffic is flooded, including ports 67/68 traffic if those ports are part of
the
udp-port-list
.
