Cisco CCNA (640-553) Security Training
Using the “cache disable” command
By Charles Ross CCNA - CCNP #CSCO10444244
In today’s article, I’m going to quickly inform you about the Cisco IOS AAA filter configuration mode command named “cache disable”.
Network Administrators (like you) use the “cache disable” command to disable a router’s cache.
Another way of saying it is; you can use this command to turn off your router’s (AAA) cache.
Note: You must enable a router’s (AAA) cache first, in order to use this command; you can enable a router’s (AAA) cache by using the “aaa cache filter” command. CCNAs normally use this command when they have to verify that the access control lists (ACLs) are being downloaded.
Below is the command’s syntax:
cache disable
As you can see, the command is extremely easy to use; because it doesn’t use any keywords or arguments.
Below is an example of the command being used:
Router>enable
Router#configure terminal
Router(config)#aaa cache filter
Router(config-aaa-filter)#cache disable
Router(config-aaa-filter)#end
Router#copy run start
In the example above, the router’s (AAA) cache is being disabled (turned off).
By the way, if you decide to use the command, make sure your router(s) is running Cisco IOS 12.2(13)T or higher.
I hope this article was very informative and helped you quickly understand the usage of the cache clear age command. If you need to learn more; I suggest you visit my website, (www.ittechtips.com) were you’ll find the latest information regarding the Cisco CCNA (640-553) Security exam techniques.
