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.
Table 35-2
Commands to Clear Caches, Tables, and Databases
Command
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.
