Locked Myself Out of My Core Switch
« on: October 17, 2014, 07:25:51 AM »
Hi Guys,

I've done something pretty silly, I have managed to lock myself out of one of my core switches. basically yesterday I had a network outage due to a problem on the switch my servers are connected to. However before working out exactly where the problem was I tried to SSH into my core switch, now as I have just taken on this role, it actually turns out the password I had on file was wrong. However, the actual core switch would not allow me to SSH in at all. So I loaded up the JDM and enabled secure SSH. Now I cant get into the switch. JDM tells me I can't find the switch, SSH through putty just give me a blank screen and telnet fails completely.

Does anyone have any suggestions as to how I might be able to get back into my switch?

Regards

Andrew

Hi Andrew,

If you have another CPU present in the switch, try to telnet/ssh via it. Have you tried via console ? There are other ways too, but conditions apply.  :D If you raise a SR with Avaya, they will help you out for password recovery. Sorry if i could not be of more help.

Cheers,
Suraj

What is the switch model and what software release is it running?

Hi Pat,

Again I seem to have left out some very important details. My core switchs are Nortel 1612G's. The one core can get at seems to be running version 2.1.4.0. I would have assumed both my cores would be running the same software version. But I don't know of any other way of checking as I cant actually get into the switch.

Suraj, what do you mean by another CPU? Central Processing Unit? I wasnt aware the switch could have more than one, how would I check if there is 2?

It would seem that the only interface I can actually get to is the web interface, and all the credentials I have don't seem to work. So unfortunately telnet and SSH are out. Going in via console also does not work unfortunately.

As my switches are Nortel, will Avaya still me?

Regards
Andrew

Sorry buddy, i thought the switches are modular (8600/8800). 1600's are almost extinct :) But if you have contract, Avaya will give you best effort support. Sorry i could not be of more help.
