DES-7200 Configuration Guide Chapter 5 Port-based Flow Control Configuration
5-2
In the interface configuration mode, you can disable the storm control on the
appropriate interface by using the no storm-control broadcast, no storm-control
multicast, or no storm-control unicast command.
The following example enables the multicast storm control on GigabitEthernet 0/1 and
set the allowed rate as 4M.
DES-7200# configure terminal
DES-7200(config)#
interface GigabitEthernet 0/1
DES-7200(config-if)#
storm-control multicast 4096
DES-7200(config-if)# end
Note
1. By default, for DES-7200 series, the storm control function for
broadcast, multicast and unknown unicast packets is disabled.
3. For DES-7200 series, the level-based storm control has certain
errors for the packets in the length of more than 64 bytes. The longer
the packet length is, the greater the comparable error value is. The
error formula is (packet length-64)/84.
4. The reference bandwidth for the level-based storm control is the
maximum bandwidth supported by the physical port, but not converted
from the bandwidth of the physical port in service.
5. If you enable storm control with the storm-control broadcast
command, the default setting or 14880PPS is used.
5.1.3 Viewing the Enable Status of
Storm Control
To view the storm control status of the interface, use the following command:
Command Function
DES-7200# show storm-control
[interface-id]
Show storm control information.
The instance below shows the enabled status of the storm control function of interface
Gi1/3:
DES-7200# show storm-control gigabitEthernet 0/3
Interface Broadcast Control Multicast Control Unicast Control action
GigabitEthernet 0/3 Disabled Disabled Disabled none
You can also view the enabling status of the storm control function of all interfaces at a
time:
DES-7200# show storm-control
Interface Broadcast Control Multicast Control Unicast Control Action
