Unable to ping IE3200

[david.appleby]

Hi i have deployed two new IE3200 switches all in a network with one ip addressed VLAN. All devices connected to these switches are communicating and i can remotely access, but I am unable to ping or telnet into the new switches anymore (i could do both when they were deployed a couple of weeks ago).

If i telnet into a switch between my two new switches, i can see both new switches via the command "Show CDP Neighbour" but even this switch, which is directly connected to both new switches, cannot get a ping response from either.

As i am relatively inexperienced i am hoping it is something simple i've missed but i can't seem to find a solution.

Any advice would be much appreciated.

Looks for me Routing issue, check the Routing from the new switch, since you able to login using other switch, so this looks for me you able to telnet on same subnet i guess ?

It turns out an unknown actor had changed my device IPs and removed the default gateway via SSH. That's why i couldn't ping my management VLAN anymore.
