IP Performance Optimization Configuration 
When configuring IP performance, go to these sections for information you are interested in: 
IP Performance Overview 
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 S5500-EI 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.
