Configuring Storm Control from INTERFACE
Mode
To configure storm control, use the following command.
You can only configure storm control for ingress traffic in INTERFACE mode. If you configure storm control
from both INTERFACE and CONFIGURATION mode, the INTERFACE mode configurations override the
CONFIGURATION mode configurations.
• Configure storm control.
INTERFACE mode
• Configure the percentage of broadcast traffic allowed on an interface (ingress only).
INTERFACE mode
storm-control broadcast packets_per_second in
• Configure the percentage of multicast traffic allowed on C-Series or S-Series interface (ingress only)
network only.
INTERFACE mode
storm-control multicast packets_per_second in
• Shut down the port if it receives the PFC/LLFC packets more than the configured rate.
INTERFACE mode
storm-control pfc-llfc pps in shutdown
NOTE: PFC/LLFC storm control enabled interface disables the interfaces if it receives continuous PFC/
LLFC packets. It can be a result of a faulty NIC/Switch that sends spurious PFC/LLFC packets.
Configuring Storm Control from
CONFIGURATION Mode
To configure storm control from CONFIGURATION mode, use the following command.
You can configure storm control for ingress traffic in CONFIGURATION mode. Do not apply per-virtual local
area network (per-VLAN) quality of service (QoS) on an interface that you have enabled storm-control (either
on an interface or globally).
• Configure storm control.
CONFIGURATION mode
• Configure the packets per second of broadcast traffic allowed in the network.
CONFIGURATION mode
storm-control broadcast packets_per_second in
• Configure the packets per second (pps) of multicast traffic allowed on C-Series and S-Series networks
only.
CONFIGURATION mode
storm-control multicast packets_per_second in
