Broadcast Storm Control
On the Aggregator, the broadcast storm control feature is enabled by default on all ports, and disabled on a port when an iSCSI
storage device is detected. Broadcast storm control is re-enabled as soon as the connection with an iSCSI device ends.
Broadcast trac on Layer 2 interfaces is limited or suppressed during a broadcast storm. You can view the status of a broadcast-
storm control operation by using the
show io-aggregator broadcast storm-control status command. You can
disable broadcast storm control by using the
no io-aggregator broadcast storm-control command.
Dell Networking OS Behavior: If broadcast trac exceeds 1000 Mbps, the Aggregator limits it to 1000 Mbps per port-pipe.
Supported Modes
