51.3.6 Detecting and Maintaining IP Address

(1) Clearing Cache, List and Database
Clearing cache, list and database You can clear all content in a cache, list or the database. When you think
some content is ineffective, you can clear it.
Run the following command in management mode to clear the cache, list and database:

also can display the reachability of the port and the routes that the message takes when the message runs in
the network.
All relative operations are listed in the following table. For how to use these commands, refer to Chapter “IP
Addressing Commands”. Run the following commands in management mode:
Command
