I am having some trouble with the ping command on a 2950 switch. I have 2 laptops, IP 192.168.0.4 and .5 connected to ports 2 and 3 on the switch. The switch is 192.168.0.2 and is connected via port 1 to a 3500 series router, IP 192.168.0.1. I can ping from the laptops to the switch and the router via command prompt. I can not ping the laptops from the switch or router.
Anyone have any suggestions on what to do now? I've already changed out each device with another, and it is the same issue replicated each time.
Based on your description of the symptoms my first guess would be that the PCs are running a firewall and that the firewall is not permitting ping to the PC. Can you check on the PCs and verify whether they are running firewalls or not?
