Cisco port not forwarding

  • 772

I have a Cisco 3750 stack. When I try and ping a device connected to one of the interfaces, the output packets counters on the interface do not increase. The input packets counter on the interface is increasing however (irrespective of whether I'm pinging the device). None of the error counters are increasing, and I am getting both an ARP entry and a mac-address-table entry. The IP I'm pinging from is in the right VLAN and subnet to ping the device. Any ideas what I can do to troubleshoot this error?

    I wouldn't be terribly concerned about the output counters not incrementing - cisco always has "interesting" counter bugs. Try unshutting VLAN1, sometimes it is shutdown by default.
