Introduction to IP Performance Configuration

In some network environments, you need to adjust the IP parameters to achieve best network
performance. The IP performance configuration supported by S4500 Series Ethernet Switches
includes:

Configuring TCP attributes

Disabling ICMP to send error packets

Introduction to FIB

Every switch stores a forwarding information base (FIB). FIB is used to store the forwarding information
of the switch and guide Layer 3 packet forwarding.
You can know the forwarding information of the switch through the FIB table. Each FIB entry includes:
destination address/mask length, next hop, current flag, timestamp, and outbound interface.
When the switch is running normally, the contents of the FIB and the routing table are the same.

IP Performance Configuration Task List

Complete the following tasks to configure IP performance:
Configuring TCP Attributes
Disabling ICMP to Send Error Packets
Configuring TCP Attributes
TCP optional parameters that can be configured include:
synwait timer: When sending a SYN packet, TCP starts the synwait timer. If no response packets
are received before the synwait timer times out, the TCP connection is not successfully created.
finwait timer: When the TCP connection is changed into FIN_WAIT_2 state, finwait timer will be
started. If no FIN packets are received within the timer timeout, the TCP connection will be
