IP Addressing 199
The following is an example of the CLI commands:
UDP Relay
Switches do not typically route IP Broadcast packets between IP subnets.
However, if configured, the switch can relay specific UDP Broadcast packets
received from its IPv4 interfaces to specific destination IP addresses.
To configure the relaying of UDP packets received from a specific IPv4
interface with a destination UDP port:
1
Click System > IPv4 Addressing > UDP Relay in the tree view to display
the
UDP Relay: Summary page.
The UDP relays are displayed.
2 To add a UDP relay, click Add , and enter the fields:
–
Source IP Address — Select the source IP address to where the switch
is to relay UDP Broadcast packets, based on a configured UDP
destination port. The interface must be one of the IPv4 interfaces
configured on the switch. Select
All for all addresses.
–
UDP Port (1 - 65535) — Check Default Services to select all of the
following default ports:
• IEN-116 Name Service (port 42)
•DNS (port 53)
console(config)# arp 198.133.219.232 00-00-0c-40-0f-bc
console(config)# arp timeout 12000
console(config)# exit
console# show arp
ARP timeout: 12000 Seconds
