1.1.2 qos lr outbound
Syntax
qos lr outbound cir committed-information-rate [ cbs committed-burst-size ]
undo qos lr outbound
View
Ethernet interface view, port group view
Parameters
outbound: Limits the rate of the outbound traffic.
cir committed-information-rate: Specifies the committed information rate (CIR) in kbps.
The range of CIR varies with port types as follows:
z Fast Ethernet port: 64 to 100000
z GigabitEthernet port: 64 to 1000000
z Ten-GigabitEthernet port: 64 to 10000000
Note that the committed-information-rate argument must be a multiple of 64.
cbs committed-burst-size: Specifies the committed burst size in bytes.
z The committed-burst-size argument ranges from 4000 to 16000000.
z If the cbs keyword is not used, the system uses the default committed burst size,
that is, 500 ms x committed-information-rate, or 16000000 if the multiplication is
more than 16000000.
Description
Use the qos lr outbound command to limit the rate of outbound traffic via physical
interfaces.
Use the undo qos lr outbound command to cancel the limit.
Examples
# Limit the outbound traffic rate on Ethernet 2/0/1 within 640 kbps.
<Sysname> system-view
[Sysname] interface Ethernet 2/0/1
[Sysname-Ethernet2/0/1] qos lr outbound cir 640
