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 S3600 Series Ethernet Switches
includes:
Configuring TCP attributes
Enabling reception of directed broadcasts to a directly connected network
Disabling ICMP to send error packets
Canceling the System-Defined ACLs for ICMP Attack Guard
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.
