For information on the command syntax, refer to the syntax of the show arp command under

“Displaying the ARP cache”

on page 226.

Displaying the forwarding cache

To display the IP Forwarding Cache for directly connected hosts, enter the following command.

Syntax: show ip cache [<ip-addr>] [| begin <expression> | exclude <expression> | include

<expression>]

The <ip-addr> parameter displays the cache entry for the specified IP address.

The show ip cache command shows the forwarding cache usage on each interface module CPU.
The CPU on each interface module builds its own forwarding cache, depending on the traffic. To
see the forwarding cache of a particular interface module, use the rconsole.

You also use the rconsole to display the IP Forwarding Cache for network entries.
