5000 Series Layer 2/3 Managed Data Center Switch CLI Reference Guide Parameters server-address discard dest-udp-port port-name IPv4 unicast or directed broadcast address to which relayed UDP broadcast packets are sent. The server address cannot be in a subnet on the interface where the relay entry is configured, and cannot be an IP address configured on any interface of the local router. Matching packets should be discarded rather than relayed, even if a global ip helper-address configuration matches the packet. (Optional) Destination UDP port number from 0 to 65535. (Optional) The destination UDP port may be optionally specified by its name. Whether a port is specified by its number or its name has no effect on behavior. The names recognized are as follows: • DHCP (port 67) • domain (port 53) • isakmp (port 500) • mobile-ip (port 434) • nameserver (port 42) • netbios-dgm (port 138) • netbios-ns (port 137) • NTP (port 123) • pim-auto-rp (port 496) • tacacs (port 49) • tftp (port 69) • time (port 37) Other ports must be specified by number. Default The default is as follows: helper addresses are not configured. Command Mode Interface Config Example To relay DHCP packets received on interface 0/2 to two DHCP servers, 192.168.10.1 and 192.168.20.1, use the following commands. (Routing)#config (Routing)(Config)#interface 0/2 (Routing)(Interface 0/2)#ip helper-address 192.168.10.1 dhcp (Routing)(Interface 0/2)#ip helper-address 192.168.20.1 dhcp To relay both DHCP and DNS packets to 192.168.30.1, use the following commands. (Routing)#config (Routing)(Config)#interface 0/2 (Routing)(Interface 0/2)#ip helper-address 192.168.30.1 dhcp (Routing)(Interface 0/2)#ip helper-address 192.168.30.1 dns 726
