Brocade Network OS Administrator’s Guide v4.1.1 - Manual (Page 501)

1. Enter global configuration mode.
switch# configure terminal
2. Specify the Ethernet interface.
The gigabitethernet rbridge-id/slot/port operand is used only for the Brocade VDX 6710, Brocade
VDX 8770-4, and Brocade VDX 8770-8. The prompt for these ports is in the following format:
switch(config-if-gi-22/0/1)#.
switch(config)# interface tengigabitethernet 1/1/2
3. Enable an Ethernet PFC on the interface.
switch(conf-if-te-1/1/2)# qos flowcontrol pfc 3 tx on rx on
4. Return to privileged EXEC mode.
switch(conf-if-te-1/1/2)# end
5. Enter the copy command to save the running-config file to the startup-config file.
switch# copy running-config startup-config
NOTE
To disable Ethernet PFC from an interface, enter no qos flowcontrol pfc cos value
Configuring rate limiting
Refer also to Multicast rate limiting on page 476.
To create a receive queue multicast rate-limit, perform the following steps from privileged EXEC mode.
1. Enter global configuration mode.
switch# configure terminal
2. Create a lower maximum multicast frame expansion rate. In this example, the rate is set to 10000
pps.
switch(config)# qos rcv-queue multicast rate-limit 10000
3. Return to privileged EXEC mode.
switch(config)# end
4. Enter the copy command to save the running-config file to the startup-config file.
switch# copy running-config startup-config
Configuring BUM storm control
Refer also to BUM storm control on page 476.
To configure storm control on the 10-gigabit Ethernet interface 101/0/2, with the broadcast traffic type
and limit-rate of 1000000 bps, perform the following steps:
1. Enter global configuration mode.
switch# configure terminal
2. Specify the Ethernet interface for the traffic you want to control. In the following example, interface
101/0/2 is in rbridge-id/slot/port format:
switch(config)# interface tengigabitethernet 101/0/2
3. Issue the storm-control ingress command to set a traffic limit for broadcast traffic on the interface:
switch(conf-if-te-101/0/2)# storm-control ingress broadcast 1000000
4. Verify the storm control verification with the show storm-control command.
switch(conf-if-te-101/0/2)# do show storm-control
Interface Type rate (Mbps) conformed violated total
