Clearing Caches, Tables, and Databases

You can remove all contents of a particular cache, table, or database. Clearing a cache, table, or database
might be necessary when the contents of the particular structure are or suspected to be invalid.
You can use any of the privileged EXEC commands in
and databases:
Table 31-4 Commands for Clearing Caches, Tables, and Databases
Command
clear ip cgmp
clear ip dvmrp route {* | route}

Purpose
Change the metric added to DVMRP routes advertised in incoming
interfaces.
The keywords have these meanings:
• (Optional) in—Specifies that the increment value is added to
incoming DVMRP reports and is reported in mrinfo replies.
• (Optional) out—Specifies that the increment value is added to
outgoing DVMRP reports for routes from the DVMRP routing
table.
If neither in nor out is specified, in is the default.
For increment, specify the value that is added to the metric of a DVMRP
router advertised in a report message. The range is 1 to 31.
If the ip dvmrp metric-offset command is not configured on an
interface, the default increment value for incoming routes is 1, and the
default for outgoing routes is 0.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
Table 31-4
Purpose
Clear all group entries the Catalyst switches have
cached.
Delete routes from the DVMRP routing table.
