Monitoring and Maintaining IP Addressing

When the contents of a particular cache, table, or database have become or are suspected to be invalid, you
can remove all its contents by using the clear privileged EXEC commands. The Table lists the commands for
clearing contents.
Table 6: Commands to Clear Caches, Tables, and Databases
clear arp-cache
clear host {name | *}
clear ip route {network [mask] | *}
You can display specific statistics, such as the contents of IP routing tables, caches, and databases; the
reachability of nodes; and the routing path that packets are taking through the network. The Table lists the
privileged EXEC commands for displaying IP statistics.
