| If an IP server or subnet entry is invalid, a switch will not try to forward UDP |
packets to the configured device or subnet address.
Subnet Masking for UDP Forwarding Addresses
The subnet mask for a UDP forwarding address is the same as the mask applied to the subnet on which the inbound UDP broadcast packet is received. To forward inbound UDP broadcast packets as limited broadcasts to other subnets, use the broadcast address that covers the subnet you want to reach. For example, if VLAN 1 has an IP address of 15.75.10.1/24 (15.75.10.1 255.255.255.0), then you can configure the following unicast and limited broadcast addresses for UDP packet forwarding to subnet 15.75.11.0:
Forwarding Destination Type | IP Address |
|
|
UDP Unicast to a Single Device in the 15.75.11.0 Subnet | 15.75.11.X |
UDP Broadcast to Subnet 15.75.11.0 | 15.75.11.255 |
