Can't access c3550 over network

EasthillMike · ‎04-08-2015

Hello!

I'm having trouble getting my c3550 to communicate on my network. I believe that I've set it up correctly, but there's obviously something wrong. I would appreciate any insight you may have. My network is currently 192.168.0.0/22 without VLANs. Here's some device output:

Hi,

Few question:

1- From were and how are you trying to access?

2- Are you able to ping this device from that machine/device from which you are trying to access?

3- how are you trying to access( Telnet/ssh) have you enable this on line vty?

Regards

Inayath

Thanks for the response!

If I understand your questions correctly,

1 - I'm attempting to access the switch across my network (via wired ethernet) from my admin workstation. The switch does not respond to network discovery attempts, including ping.

2 - I'm unable to ping the switch or any device connected to it from my admin computer. Also, devices connected to the switch can't ping each other, the switch, or any network IP.

3 - The only access I have right now is through the serial console.

I should probably also mention that this switch is being configured on my bench before deployment - if I can get it to work.
