Note:

This topic applies only to the J-Web Application package.

You can use the J-Web interface to define CoS classifiers on an EX Series switch. Classifiers examine the CoS value or alias of an incoming packet and assign the packet a level of service by setting its forwarding class and loss priority.

To define CoS classifiers:

Select Configure > Class of Service > Classifiers.

Note:
After you make changes to the configuration on this page, you must commit the changes immediately for them to take effect. To commit all changes to the active configuration, select Commit Options > Commit. See Using the Commit Options to Commit Configuration Changes (J-Web Procedure) for details about all commit options.
Click one of the following options:
- Add—Adds a classifier. Enter information into the classifier page as described in Table 1.
- Edit—Modifies an existing classifier. Enter information into the classifier page as described in Table 1.
- Delete—Deletes an existing classifier.

Table 1: Classifiers Configuration Fields
Field	Function	Your Action
Classifier Name	Specifies the name for a classifier.	To name a classifier, type the name—for example, ba-classifier.
Classifier Type	Specifies the type of classifier: dscp, ieee-802.1, or inet-precedence.	Select a value from the list.
Code Point Mapping	Sets the forwarding classes and the packet loss priorities (PLPs) for specific CoS values and aliases.	To add a code point mapping: Click Add. Select the code point. Select a forwarding class from the following list: expedited-forwarding—Provides low loss, low delay, low jitter, assured bandwidth, and end-to-end service. Packets can be forwarded out of sequence or dropped. best-effort—Provides no special CoS handling of packets. Typically, RED drop profile is aggressive and no loss priority is defined. assured-forwarding—Provides high assurance for packets within the specified service profile. Excess packets are dropped. network-control—Packets can be delayed but not dropped. Select the loss priority. To assign a loss priority, select one: high—Packet has a high loss priority. low—Packet has a low loss priority.
