IP Performance Overview
Introduction to IP Performance Configuration
In some network environments, you can adjust the IP parameters to achieve best network performance.
The IP performance optimization configuration supported by S4500 Series Ethernet Switches includes:
z Configuring TCP attributes
z 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 by viewing the FIB table. Each FIB entry includes:
destination address/mask length, next hop, current flag, timestamp, and outbound interface.
When the switch runs normally, its FIB table and routing table have the same contents.
