In today’s article, I’m going to inform you about the Cisco IOS privileged EXEC mode command named “clear crypto gdoi.” A Group Domain of Interpretation (GDOI) group member’s current session with the key server can be cleared using this command by network administrators like you.

Below is the command’s syntax:

clear crypto gdoi [group group-name | ks coop counters | ks policy | replay counter]

group group-name – This (optional) keyword and argument combination is used to give a group a name.

ks coop counters – The counters on the cooperative key server are cleared using this (optional) keyword.

ks policy – The policies on a key server can all be cleared using this (optional) keyword. Keep in mind that using this keyword does not cause (trigger) the re-election of the key servers.

replay counter – The anti-replay counters are cleared using this optional keyword.

Note: A group member’s policy (state) will be deleted (cleared) if you run this command on them; as a result, they will need to re-register with the key server.

And, if you perform this command on a key server, its “state” will be deleted (cleared). Furthermore, if this command is run on a server and redundancy between servers is required, that server will enter election mode once more in order to choose a new primary server.

As a side note, if you choose to use the command, ensure that your router(s) are running Cisco IOS 12.4(11)T or higher.

I sincerely hope that this article was very helpful and made it easy for you to understand how to use the clear crypto gdoi command. You can find the most recent information about the Cisco CCNA (640-553) Security exam techniques on my website, so I recommend visiting it if you want to learn more.
