I have a vulnerability scan performed by an outside vendor. My Cisco 2901 keeps getting flagged for having port 2002 open, which is a common port for some worms or something.

After doing some research I think that port 2002 is associated with line 2. Does anyone know how to close/remove this port and make some changes to line 2 so this port doesnt show up on my vuln scans?? Thanks so much for any help.

line 2
 no activation-character
 no exec
 transport preferred none
 transport input all
 transport output pad telnet rlogin lapb-ta mop udptn v120 ssh
 stopbits 1

We can not close only port 2002 on Line2.

Either we have to disable line2 completely or limit access to it defining an access-list.

Thanks for the quick reply. I dont think I'm using line 2, how would I find out if I'm using it. How would I disable it?

"Show Run" output will display the Line 2 configuration.
"Show Line" displays Line2 to details.

To disable Line 2 completely.
R1(config)#line 2
R1(config-line)#transport input none
R1(config-line)#end

Open in new window

Your config will look like
line 2
 transport input none

Open in new window

That worked, thanks very much for the help. I'm familiar with all of those commands but wasnt sure it would be that simple for line 2. I was not that familiar with line 2. Thanks again!
