Unable to ping Cisco switch
Posted on 2013-01-22
Recfently, one of our Cisco switches has stopped responding to ping. It was contactable a few days ago but one day it stopped responding to ping only. We can successfully telnet to the device and login. This device cannot ping any device in the same domain except one router that is directly connected to it. It can also ping 4 switches that are connected together via trunk ports and are in the same VTP domain. There is another router connected to it that it cannot ping nor can the router ping it however, the router can ping the other 4 switches. It was also able to do this last week.
I have had a look at the config but i cannot see anything that would be stopping it from responding.
