Huawei quidway s7700 - Optional) Setting the Length of the Interface Queue

NOTE
You need to create a port group before performing this task. For details about creating an interface group,
see Configuring the Interface Group in the Quidway S7700 Smart Routing Switch Configuration Guide -
Ethernet.
Step 3 Run:
qos lr cir cir-value [ cbs cbs-value ] [ outbound ]
The rate for traffic shaping on an interface is set.
By default, the CIR for traffic shaping on an interface is the maximum bandwidth of the interface.
For example, the CIR for traffic shaping on an Ethernet interface is 100000 kbit/s; the CIR for
traffic shaping on a GE interface is 1000000 kbit/s ; the CIR for traffic shaping on a 10GE
interface is 10000000 kbit/s.
NOTE
l If this command is run repeatedly on the same interface, the latest configuration overrides the previous
configuration.
l On an MPLS Traffic Engineering (TE) tunnel, the CIR for traffic shaping set through the qos lr
command must be greater than the maximum reservable bandwidth of the MPLS TE tunnel if the
maximum link bandwidth and maximum reservable bandwidth of the MPLS TE tunnel are set;
otherwise, the maximum reservable bandwidth of the MPLS TE tunnel cannot be provided.
l If traffic shaping in an interface queue is configured on the same interface, the CIR for traffic shaping
on an interface must be greater than or equal to the sum of CIRs for traffic shaping in an interface
queue. Otherwise, traffic shaping fails. For example, traffic of lower priorities preempts the bandwidth
of traffic of higher priorities.

2.4.3 (Optional) Setting the Length of the Interface Queue
This section describes how to set the length of the interface queue and the length of the specified
priority queue.
Context
The length of the interface priority queue is automatically managed by the system. You can set
the length of the interface priority queue as required by using the qos queue command.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The interface view is displayed.
Step 3 Run:
qos queue queue-index length length-value
The length of the interface priority queue is set.
