Can anyone help me with what I'm missing when it comes to configuring a 2821 router with a NM-16A module for a terminal server.
Here is my config
interface ethernet g0/0
ip address 10.1.1.3 255.255.255.0
ip host R1 2065 10.1.1.3
ip route 0.0.0.0 0.0.0.0 10.1.1.1
int group async 0
line 1/0 1/15
line aux 0
line 1/0 1/15
transport input telnet
transport output telnet
I verified the vty lines by using the "show line" command, they were 65-96
Do I need a loopback interface, I didn't think I did, it was just recommended. Any help would be appreciated.
For terminal server, you usually use a loopback interface.
Have a look at this link with config example:
While I agree with my colleague Reza that loopback interfaces are frequently used with terminal servers, it is certainly not a requirement. The requirement is really to have a working IP address on the router. So my question to the original poster is whether the address on Gig0/0 is really active. The best way to show this would probably be to post the output of show ip interface brief.
I would also ask the original poster to tell us what cable he is using to connect the async interface to the console of the other router/switch?
Hello. The interface is active and I'm able to access the router remotely in that IP. As for the cable, I'm using the octal ones. Whatever its called. CAB-OCTAL-ASYNC
Thanks for the additional information.
I have not configured terminal server functionality on a 2821 and so do not have experience to work from. I have configured terminal servers many times and in general it is not a difficult feature to configure.
I would suggest that you remove this line from the configuration and let us know if the behavior changes.
