A company has a service level agreement (SLA) with its service provider. The SLA specifies a 2
Mbps committed information rate (CIR) and 20 KB committed burst size (CBS). Lately, during
peak usage times, the company has been experiencing brief periods of poor performance on its
external connection (GigabitEthernet port 2/0/1 on an HP 5800 switch).
How can the network administrator configure the Comware switch to address this problem?

A.
Configure a traffic classifier that selects all traffic and a car traffic behavior that sets the CIR to
2 Mbps and the CBS to 20 KB. Create a QoS policy that maps the classifier to the action and
apply this policy as an inbound policy on port GigabitEthernet 2/0/1.

B.
Enable Strict Priority (SP) scheduling on port GigabitEthernet 2/0/1 and ensure that all inbound
traffic is marked with the correct priority.

C.
Configure generic traffic shaping (GTS) on the GigabitEthernet port 2/0/1, setting the CIR to 2
Mbps and the CBS to 20 KB.

D.
Configure a traffic classifier that selects all traffic and a car traffic behavior that sets the CIR to
2 Mbps and the CBS to 20 KB. Create a OoS policy that maps the classifier to the action and
apply this policy as an outbound policy on port GigabitEthernet 2/0/1.

Explanation:
Generic Traffic Shaping (GTS): Shapes irregular traffic or traffic exceeding the predefined specifications to facilitate bandwidth assignment in upstream and downstream networks.
The nonconforming traffic is cached, so that fewer packets are dropped.

* CBS

Note 2: CIR: Acronym for Committed Information Rate, the average rate (bits per second) at
which the network guarantees to transfer information units over a specific
measurement interval. This interval is the quotient of committed burst size divided
by committed information rate (CBS/CIR).
Note 3: CBS Acronym for Committed Burst Size, a congestion control setting typically used in
wide-area networks connecting multiple local-area networks. A CBS specifies
the maximum number of packets transmittable during a specified interval.
