Configuring CoS Classifiers (NSM Procedure)

Table 58: Configuring and Applying Behavior Aggregate Classifiers

Task
Configure behavior aggregate
classifiers for DiffServ CoS.
124
Packet classification associates incoming packets with a particular class-of-service
(Cos) servicing level. Classifiers associate packets with a forwarding class and loss priority
and, based on the associated forwarding class, assign packets to output queues. JUNOS
software supports two general types of classifiers:
Behavior aggregate or CoS value traffic classifiers—Examines the CoS value in the
packet header. The value in this single field determines the CoS settings applied to the
packet. BA classifiers allow you to set the forwarding class and loss priority of a packet
based on the Differentiated Services code point (DSCP) value, IP precedence value,
and IEEE 802.1p value. The default classifier is based on the DSCP value.
Multifield traffic classifiers—Examines multiple fields in the packet such as source and
destination addresses and source and destination port numbers of the packet. With
multifield classifiers, you set the forwarding class and loss priority of a packet based
on firewall filter rules.
To configure and apply behavior aggregate classifiers for the switch:
In the navigation tree, select Device Manager > Devices.
1.
Click the Device Tree tab, and then double-click the device for which you want to
2.
configure and apply behavior aggregate classifiers.
Click the Configuration tab. In the configuration tree expand Class of Service.
3.
Select Classifiers.
4.
Add or modify settings as specified in Table 58 on page 124.
5.
Click one:
6.
OK—Saves the changes.
Cancel—Cancels the modifications.
NOTE: After you make changes to a device configuration, you must push that
updated device configuration to the physical security device for those changes
to take effect. You can update multiple devices at one time. See the Network
and Security Manager Administration Guide for more information.
Action
1. Click Add new entry next to Dscp.
2. In the Name box, type the name of the behavior aggregate classifier—for example,
ba-classifier.
3. In the Import box, type the name of the default DSCP map.
