542 Configuring Routing
• Source IP Interface — Select the interface to use for UDP/Helper relays. Select All to configure relay
entries on all available interfaces.
•
UDP Destination Port — Identifies destination UDP port number of UDP packets to be relayed. For a
list of UDP Port allocations, see Table 9-20.
•
Server Address — The IPv4 address of the server to which packets are relayed for the specific UDP
Destination Port.
•
IsDiscard — If True, packets arriving on the given interface with the given destination UDP port are
discarded rather than relayed. Discard entries are used to override global IP helper address entries
which otherwise might apply to a packet.
•
Hit Count — The number of times a packet has been forwarded or discarded according to this entry.
•
Remove — Select this option and click Apply Changes to remove the relay from the selected source IP
interface.

Datagram Server (port 138), TACACS Server (Port 49), and Time Service (port 37).
5. Choose whether to discard (True) or keep (False) packets arriving on the given interface with the
given destination UDP port.
6.
Enter the IP address of the server to which the packets with the given UDP Destination Port will be
relayed.
7. Click Apply Changes .
