SECE/4/STORMCTRL_BC_BLOCKED
Possible Causes
A broadcast storm occurred on the interface, and the rate of broadcast packets received on the interface exceeded the upper threshold. As a result, broadcast packets were blocked on the interface.
Procedure
- Check whether the broadcast storm is caused by a loop. If so, remove the loop. When the average rate of broadcast packets received on the interface falls below the lower threshold, broadcast packets are properly forwarded by the interface. For the broadcast storm troubleshooting procedure, see MAC Address Flapping Occurs on a Layer 2 Network and STP Faults Occur in the Revelations of Troublesolving.
