Cli Example - Dell PowerConnect M6348 Configuration Manual

Configuring a storm-control level also enables that form of storm-control. Disabling a storm-control level
(using the "no" version of the command) sets the storm-control level back to default value and disables
that form of storm-control. Using the "no" version of the "storm-control" command (not stating a
"level") disables that form of storm-control but maintains the configured "level" (to be active next time
that form of storm-control is enabled).
NOTE:
The actual rate of ingress traffic required to activate storm-control is based on the size of incoming packets
and the hard-coded average packet size of 512 bytes - used to calculate a packet-per-second (pps) rate - as the
forwarding-plane requires pps versus an absolute rate kbps. For example, if the configured limit is 10%, this is
converted to ~25000 pps, and this pps limit is set in forwarding plane (hardware). You get the approximate desired
output when 512bytes packets are used.

CLI Example

The following examples show how to configure the storm control feature an Ethernet interface. The
interface number is 1/g17.
Example #1: Set Broadcast Storm Control for an Interface
console#configure
console(config)#interface ethernet 1/g17
console(config-if-1/g17)#storm-control broadcast ?
<cr>
level
console(config-if-1/g17)#storm-control broadcast level ?
<rate>
console(config-if-1/g17)#storm-control broadcast level 7
Example #2: Set Multicast Storm Control for an Interface
console(config-if-1/g17)#storm-control multicast level 8
Example #3: Set Unicast Storm Control for an Interface
console(config-if-1/g17)#storm-control unicast level 5

System Configuration
Press enter to execute the command.
Configure storm-control thresholds.
Enter the storm-control threshold as percent of port
speed. Percent of port speed is converted to
PacketsPerSecond based on 512 byte average packet
size and applied to HW. Refer to documentation for
further details.
