Broadcast, unknown multicast, and DLF packets switched at a very low rate

Symptom: Broadcast, unknown multicast, and DLF packets are switched at a very low rate.

By default, broadcast storm control is enabled on an Aggregator and rate limits the transmission of broadcast, unknown multicast, and DLF packets to 1Gbps. This default behavior is designed to avoid unnecessarily flooding these packets on all (4094) VLANs on all Aggregator interfaces (default configuration).

Resolution: Disable broadcast storm control globally on the Aggregator.

Steps to Take:

  1. Display the current status of broadcast storm control on the Aggregator (show io-aggregator broadcast storm-control status command).
    Dell#show io-aggregator broadcast storm-control status 
                                        
                                        Storm-Control Enabled
                                        
                                        Broadcast Traffic limited to 1000 Mbps
                                     
  2. Disable broadcast storm control (no io-aggregator broadcast storm-control command) and re-display its status.
    Dell#config terminal 
                                        Dell(conf)#no io-aggregator broadcast storm-control 
                                        Dell(conf)#end 
                                        Dell#show io-aggregator broadcast storm-control status 
                                        
                                        Storm-Control Disabled
