Mushtaq - this is the correct operation (you don't need to use the key if already unlocked the door). Now, you should be able to get through the router by whatever method you have in your dynamic ACL. Give it a try again and maybe post your configs too.

Dave,
 
You are right, The router took the command when I typed in. It is strange.
Anyway, I have another issue that even though I have both the idle and absolute timeout configured but when I try to open telnet session from the Switch, the first session gets drop which is expected but when I try it second time I get the following message.
 
% List#LOCK_KEY-MYACL already contains this IP address pair
 
I tried it couple of time but no luck.
I remember seeing similar issue with someone in the groupstudy posting but in my case it is not working.

        All,
        
        I am having trouble setting idle timeout with the *timeout* keyword in
        the *
        access-enable* command in the *autocommand* command. Is this an IOS
        limitation? I checked the DOC CD for 12.3 configuration and sounds like
        it
        should be supported.
        
        Am I missing anything here? Can any one shed some light on this? Is
        there a
        way I can achieve my goal as mentioned above?
