In today’s article, I’m going to inform you about the Cisco IOS privileged EXEC mode command named “clear crypto isakmp.” CCNA’s (like you) use this command to clear active Internet Key Exchange (IKE) connections.

Below is the command’s syntax:

clear crypto isakmp [connection-id] [active | standby]

connection-id-This (optional) argument is the ID of the bitcoin dice connection that is to be cleared. If this argument is not used with the command, all existing connections will be cleared by default.

active-This (optional) keyword is used to only clear (remove) IKE security associations (SAs) that are in the active state.

standby – And, this (optional) keyword is used to only clear IKE SAs that are in the standby (secondary) state. Remember, if the router is in standby mode, the router will immediately resynchronize the standby SAs; thus, it may appear as if the standby SAs were not cleared.

In the example below, all existing IKE connections are being cleared:

Router#clear crypto isakmp

Note: You can use the privileged EXEC mode command named “show crypto isakmp sa” to display (view) current IKE SAs.

And, if you decide to use the command, make sure your router(s) is running Cisco IOS 12.3(11)T or higher.
