    Re: Spanning-tree - Hard Loop Bringing Down Network

    Hi Ciscos

     

    This feature was introduced in IOS version 12.2SE and later.  If the OP is using a switch with an IOS that predates this feature, he won't get the benefit.

    Re: Spanning-tree - Hard Loop Bringing Down Network

    I got the same issue and I tried to implement storm-control on our Cisco 4506 switch, but Storm Control does not work.

     

    interface FastEthernet2/25

    switchport access vlan 3

    switchport mode access

    storm-control broadcast level 0.36

    storm-control action shutdown

    end

     

    Core1#sh storm

    Interface  Filter State   Upper        Lower        Current

    ---------  -------------  -----------  -----------  ----------

    Fa2/25     Forwarding        0.36%        0.36%        0.00%

     

    When I create a network loop, current percentage is always 0.00%, but the performance of the 4500 is significant decreased because of broadcast storm.

     

    Is there anyone implement it successfully? Thanks
