Configuration Example
Networking Requirement
The IP address of VLAN interface 2 on the Switch is 10.110.1.1, which is connected
with network segment 10.110.0.0. Set to relay-forward the broadcast packets with
destination IP of all 1s and destination UDP port 55 in the network segment
10.110.0.0 to the destination server 202.38.1.2.
with network segment 10.110.0.0. Set to relay-forward the broadcast packets with
destination IP of all 1s and destination UDP port 55 in the network segment
10.110.0.0 to the destination server 202.38.1.2.
