2. Verify that the downstream port channel in the top-of-rack switch that connect to the Aggregator is
configured correctly.
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
