UDP Relay
NOTE: This feature is also called IP Helper. It is only relevant when a device is in
L2+ mode.
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 Network Administration > Route Settings > IPv4 Route Settings
>
UDP Relay .
The UDP relays are displayed.
2 To add a UDP relay, click Edit, 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 — Check Default Services to select all of the following
default ports:
• IEN-116 Name Service (port 42)
•DNS (port 53)
• NetBIOS Name Server (port 137)
• NetBIOS Datagram Server (port 138)
• TACACS Server (port 49)
