To associate a queue class with an interface

1.Depending on whether you are using IPv4 or IPv6, click the following link.

a.For IPv4 ACLs, click Queue Class under Configuration > Traffic Management in the tree view.

b.For IPv6 ACLs, click IPv6 Queue Class under Configuration > IPv6 Configuration > Traffic Management in the tree view.

2.In the List of Available Physical Interfaces table, click the name physical interface with which you wish to associate a queue class.

The physical interface page for the interface you selected appears.

3.To enable QoS queuing, select either Max Throughput or Min QoS Latency from the Queue Mode drop-down list.

4.Click Apply.

A drop-down list appears in the Queue Class field.

5.Select the queue class you want to associate with the interface from the Queue Class drop- down list.

If you do not select a queue class, the default class is used. The default queue class has two queues, Internetwork Control and Best Effort.

6.Click Apply.

7.Click Save to make your changes permanent.

Configuring ATM QoS

ATM networks can provide different quality of service for network applications with different requirements. Unspecified Bit Rate (UBR) service does not make any traffic related guarantees. It does not make any commitment regarding cell loss rate or cell transfer delay. Constant Bit Rate (CBR) service provides continuously available bandwidth with guaranteed QoS.

The IPSO implementation supports CBR channels through a mechanism on an ATM network interface card (NIC) that limits the cell rate for each virtual channel you configure. The CBR feature limits the peak cell rate for each CBR channel in the output direction only. Each ATM port supports up to 100 CBR channels with 64 kbits/sec of bandwidth resolution.

Create a QoS descriptor

1.Click ATM QoS Descriptor under Configuration > Traffic Management in the tree view.

2.To create an ATM QoS Descriptor, enter its name in the Create a New ATM QoS Descriptor edit box.

The category for any new ATM QoS Descriptor that you configure is set to constant bit rate (CBR). CBR limits the maximum cell output rate to adhere to the requirements on CBR traffic imposed by the network.
