Field Description
CBS
Committed burst size (CBS) in bytes, which specifies the depth of the
token bucket for holding traffic bursts
qos lr
Syntax
qos lr outbound cir committed-information-rate [ cbs committed-burst-size ]
undo qos lr outbound
View
Layer 2 Ethernet interface view, Layer 3 Ethernet interface view, port group view
Default level
2: System level
Parameters
outbound : Limits the rate of outgoing packets on the interface.
cir committed-information-rate : Sets the committed information rate (CIR) in kbps, which specifies the
average traffic rate. The CIR must be a multiple of 8, and ranges from 8 to 1000000 for a GE port and
8 to 10000000 for a 10-GE port.
cbs committed-burst-size : Committed burst size (CBS) in bytes.
•
If you do not specify the cbs keyword, the CBS is 62.5 × committed-information-rate by default and
must be a multiple of 512. If 62.5 × committed-information-rate is not a multiple of 512, the closest
higher multiple of 512 applies. The CBS cannot exceed 16000000.
•
If you specify the cbs keyword, the CBS ranges from 512 to 16000000 and must be a multiple of
512.
Description
Use the qos lr command to limit the rate of outgoing packets on the interface.
Use the undo qos lr command to remove the rate limit.
Settings in interface view take effect on the current interface. Settings in port group view take effect on all
ports in the port group.
Examples
# Limit the rate of outgoing packets on GigabitEthernet 1/0/1, with CIR 640 kbps.
