Our cat6500 (Supervisor Engine 720) started reporting packet drop storm control message in log for it's 10Gig port that is used as an interconnect to the its peers. When you run "show interfaces TenGigabitEthernet 7/2 counters nonzero", the "InBcastPkts" is showing "608825477". That number was 1/2 less 6 hours ago. Our setup is 2 x cat6500 in an active standby setup.
Message in "show log"
%PM_PLATFORM-5-PORTDROP: Port TenGigabitEthernet7/2 dropped packets due to storm control
Surprisingly it returned "Not found" when submitted through the Error Message decoder. Our storm-control is configured at 30.00. We do not have multicast traffic/applications.
How to trace the cause of this ?
