Line console 0 command

Unanswered Question
May 10th, 2010


Checking the configuration of a router, I found the following commands:

line con 0
access-class 1 in
exec-timeout 5 0

I don't understand the idea of the command access-class 1 in, untill now I have understand that the access-class is used to control the access by an ACL, but regarding the console, the connection is serial.


I have this problem too.

Just a thought - could it perhaps be effective in controlling the access to a reverse telnet session? I have played very little with these things.

Best regards,

From what I know, one can only use TTYs for reverse telnet.

I have edited my post to better clarify.

For "in" keyword, it's a minor incongruence, that can be disregarded.

For the "out" keyword, you can control to which destination it's possible to open connections.
