Broadcast, Unknown Multicast, And Dlf Packets Are Switched At A Very Low Rate; Resolution: Disable Broadcast Storm Control Globally On The Aggregator; Steps To Take - Dell PowerEdge M IO Aggregator Command Reference Manual

Broadcast, unknown multicast, and DLF packets are 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

Steps to Take:

FTOS#show io-aggregator broadcast storm-control status
Storm-Control Enabled
Broadcast Traffic limited to 1000 Mbps

FTOS#show io-aggregator broadcast storm-control status
Storm-Control Disabled
command).
no io-aggregator broadcast storm-control
