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.

Configuration Procedure
1 Enable UDP Helper function.
[SW5500]udp-helper enable
2 Set to relay-forward the broadcast packets with destination UDP port 55.
[SW5500]udp-helper port 55
3 Set the IP address of the destination server corresponding to VLAN interface 2 as
202.38.1.2.

IP performance is described in the following section.
Configuring TCP Attributes
TCP attributes that can be configured include:
synwait timer: When sending the syn packets, TCP starts the synwait timer. If
■
response packets are not received before synwait timeout, the TCP connection will
