Cisco 2960s Console Problem

[sslackjcb]

HI,

I have a 4 Cisco 2960s in a stack. I'm trying to use a console cable to connect to the switches and i am failing miserably. I have connected to the switches via telnet and the speed on the line con 0 was set to 115200. I think this was done on installation by a third party company we used. So i changed it to 9600 like the rest of our switches and i still can't connect.

Any ideas why? is there a way to reset the console interface to default? I have also noticed noise on the console port (see below)

jc-l2s-0101-001#show line console 0
   Tty Typ     Tx/Rx    A Modem  Roty AccO AccI   Uses   Noise  Overruns   Int
     0 CTY              -    -      -    -    -      0      14     0/0       -

Is this normal?

Hi Steve,

Console speed can be changed from rommon (switch: set BAUD ) or from CLI (line console 0, speed ). Have you tried connecting with baud rates of both 9600 as well as 115200 and are still unable to connect? Have you tried a different console cable and a PC for this?

Yes  i have..

When i connect with both ends at speed 115200, my characters that i enter turn into a series of hashes and other characters like $^*%(^*$%(*$*&$^(*^

I've tried a different cable and a different laptop.

After changing the console settings using CLI, did you try rebooting the switch and see it it auto negoatiates the baud rate at 9600?

Its worth giving a shot, just rebooting the switch after defaulting the config under line con 0 and let it re-intilaize everything.

Cheers,

Hi Steve,

Sounds like a hardware issue to me. Do all the switches in the stack have this problem?
