Broadcast Control
In the Broadcast Control page, you can enable and disable broadcast control for all ports on the switch.
The Broadcast Control page contains the following information:
l Port Number
l Port Type:
¡ 1000Base-TX — 10/100/1000Base-T RJ-45 port
¡ 1000Base-SFP — gigabit SFP transceiver port
The Broadcast Control page also contains the following editable fields:
l Protect Status — Allows you to enable/disable broadcast storm control for ports on the switch. When enabled, the switch employs a broadcast-control
mechanism if the packet-per-second threshold on a port is exceeded. (The default is enabled.)
l Threshold (16,64,128,256) — The packet-per-second threshold for broadcast packets received on a port. Possible values are 16, 64, 128, or 256
packets per second. (The default is 256 packets per second.) If jumbo frames are enabled on the switch, the maximum threshold for broadcast storm
control is limited to 64 pps.

CLI Commands
The following table summarizes the equivalent CLI command for items in the Ports/Broadcast Control web page.
Example
Console(config)#interface ethernet 1/5
Console(config-if)#switchport broadcast packet-rate 64
Console(config-if)#
Port Mirroring
From the Port Mirroring page, you can configure a port mirror session by setting a source and destination port pair. Port mirroring helps you debug a network.
The following options are available:
l Sessions Table — Displays the current port mirror session
NOTICE: You can enable/disable broadcast storm control on a per-port basis, but the selected packet-per-second threshold applies to all ports on the
switch.
NOTE: Broadcast control does not affect IP multicast traffic.
Command
Usage
switchport broadcast packet-rate rate
Configures broadcast storm control (applies to all ports)
NOTICE: You can configure only one port mirror session on the switch. The source and destination port have to be either both in the port range of 1 to
12 or both in the port range of 13 to 24.
