# Enable VLAN-interface 2 to forward directed broadcasts.
[SwitchA-Vlan-interface2] ip forward-broadcast
2. Configure Switch B:
# Configure a static route on Switch B.
<SwitchB> system-view
[SwitchB] ip route-static 1.1.1.0 255.255.255.0 1.1.2.1
# Configure IP addresses for VLAN-interface 3 and VLAN-interface 2.

[SwitchB-Vlan-interface3] ip address 1.1.2.2 24
[SwitchB-Vlan-interface3] quit
[SwitchB] interface vlan-interface 2
[SwitchB-Vlan-interface2] ip address 1.1.3.1 24

Configuring TCP timers
You can configure the following TCP timers:
• synwait timer—When sending a SYN packet, TCP starts the synwait timer. If no response packets
are received within the synwait timer interval, the TCP connection cannot be created.
• finwait timer—When a TCP connection is changed into FIN_WAIT_2 state, the finwait timer is
started. If no FIN packets are received within the timer interval, the TCP connection is terminated. If
a FIN packet is received, the TCP connection state changes to TIME_WAIT. If a non-FIN packet is
received, the system restarts the timer upon receiving the last non-FIN packet. The connection is
broken after the timer expires.
