Enabling Traffic Storm Control

To enable traffic storm control, perform this task:
Command
Step 1
Router(config)# interface {{type
{port-channel number}}
Step 2
Router(config-if)# storm-control broadcast level
level[.level]
Router(config-if)# no storm-control broadcast
level
OL-11439-03
FlexWAN Fast Ethernet port adapters and all WAN modules supporting Ethernet SPAs do not
support traffic storm control.
The WS-X6548-GE-TX, WS-X6548V-GE-TX, WS-X6148-GE-TX, WS-X6148A-GE-TX, and
WS-X6148V-GE-TX switching modules do not support traffic storm control, nor do versions of
these modules equipped with inline power (Power over Ethernet, or PoE) daughtercards.
The switch supports multicast and unicast traffic storm control on Gigabit and 10 Gigabit Ethernet
LAN ports. Most FastEthernet switching modules do not support multicast and unicast traffic storm
control, with the exception of WS-X6148A-RJ-45 and the WS-X6148-SFP.
The switch supports broadcast traffic storm control on all LAN ports except on those modules
previously noted.
Except for BPDUs, traffic storm control does not differentiate between control traffic and data
traffic.
When multicast suppression is enabled, traffic storm control suppresses BPDUs when the multicast
suppression threshold is exceeded on these modules:
WS-X6748-SFP
–
WS-X6724-SFP
–
WS-X6748-GE-TX
–
WS-X6748-GE-TX
–
WS-X6704-10GE
–
WS-SUP32-GE-3B
–
WS-SUP32-10GE-3B
–
When multicast suppression is enabled on the listed modules, do not configure traffic storm control
on STP-protected ports that need to receive BPDUs.
Except on the listed modules, traffic storm control does not suppress BPDUs.
