Chapter 28 Configuring Traffic Storm Control
Configuring Traffic Storm Control Support on the MWR 2941
Enabling Error Disabled Recovery
The Cisco MWR 2941 supports error disable recovery for traffic storm control. Interfaces on which
storm control action shutdown is configured will go down when a storm is detected. You can configure
automatic recovering by enabling the error disable recovery globally and setting a time interval for error
recovery. By default the error recovery is disabled.
To enable error disable recovery, complete the following task:
Step 4
storm-control {{broadcast | multicast | unicast}
level pps number}
Example:
Router(config-if)# storm-control multicast level pps
75000000
Enables broadcast, multicast, or unicast storm control
on a port, where:
• broadcast—Enables broadcast storm control on
the port.
• multicast—Enables multicast storm control on the
port.
• unicast—Enables unicast storm control on the
port.
• level pps rate—Specifies the rate of PPS. Valid
value is a number between 0 and 42949672950.
When the maximum rate of PPS is reached, the
flooding of storm packets is blocked.
Step 5
storm-control action {shut | trap}
Example:
Router(config-if)# storm-control action trap
Specifies the action taken when a storm occurs on a
port, where:
• shut—Disables the port during a storm.
• trap—Sends an SNMP trap.
The default action is to filter traffic.
Step 6
end
Example:
Router(config-if)# end
Exits interface configuration mode.
