[cisco-voip] CTL/Security Token question

[Jason Aarons (AM)]

I've never tested it but I assume you could order 4 or 5 eTokens for additional backups when you do the original install, right? Is there any limit how many eTokens you could sign and lock away?

If the password has been entered incorrectly too many times the token cannot be recovered.  Hopefully you still have one with a known password so that you can get a new token to replace the locked one.  Then update the CTL file with the new token using the one remaining token that was originally used.  That's why it's a requirement to order two, in case one is lost or locked out there is a backup.  If you've lost both here's what you'll need to do: http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/security/4_2_3/secutrbl.html#wp1032731

I would call TAC, installing a new CTL would mean visiting each phone (or use UnifiedFX) and resetting the CTL. Not something you want to have happen.

I have a customer that failed the Security Token Password 3 times and now the token is locked.
Anyone knows how to solve this problem ?
Do I need to replace the token via RMA ?


Thanks.

We do this in our labs. Just be careful to keep track of password changes. Using the tokens requires a password. Guess the wrong password too many times and they do self destruct. This would effectively lock you out of all clusters that use that key.
