SSH Account Lockout Behavior
The SSH account lockout feature is disabled by default.
1. To enable SSH account lockout:
n Perform the ssh lockout count or ssh lockout duration configuration options.
2. To disable the feature, perform ssh lockout reset.
3. If the SSH account lockout feature is configured with failed attempts=3 and unlock time = 5 minutes:
n CLI access via SSH (password-based) authentication is locked on three consecutive failed login attempts.
n If the failed password attempt continues (even after the account is locked), the unlock time shifts for the
next five minutes (as in this example) from the current time from the last failed login attempt.
n Successful password-based SSH logins are rejected during the lockout period.
n Console-based logins are allowed during the lockout period.
n SSH logins via public key methods are allowed during the lockout period.
4. Administrators can use any of the above options to reset the SSH account lockout by issuing the ssh
unlock command.
5. After the lockout period, successful SSH logins are accepted and the account is unlocked.
