Filters and QoS Configuration for ERS 5500
Technical Configuration Guide	v2.0	NN48500-559

NOTE: If you wish to combine an IP element and a L2 element for a classifier, the L2 element’s EtherType must set configured as 0x0800. The following is an example of a L2 element to match VLAN 1:

•ERS5500-48T(config)#qos l2-element 1 vlan-min 1 vlan-max 1 ethertype 0x800

b)Adding a Classifier

To add a new classifier, enter the following command:

•ERS5500-48T(config)#qos classifier <1-64000> set-id <1-64000> name <name> element-type <ipl2> element-id <1-64000>

Where element-id = IP element or L2 element ID.

Example:

Adding an IP element to a classifier:

•ERS5500-48T(config)#qos classifier 1 set-id 1 name class_1 element-type ip element-id 1

Adding an IP element and a L2 element to a classifier:

•ERS5500-48T(config)#qos classifier 2 set-id 2 name class_2 element-type ip element-id 2

•ERS5500-48T(config)#qos classifier 3 set-id 2 name class_2 element-type l2 element-id 1

c)Adding a Classifier Block

To add a new classifier block, enter the following command:

•ERS5500-48T(config)#qos classifier-block <1-64000> block-number <1-64000> name <name> set-id <1-64000>

Example:

The following commands add classifiers 1 and 4 to classifier block 1.

•ERS5500-48T(config)#qos classifier-block 1 block-number 1 name block_1 set-id 1

•ERS5500-48T(config)#qos classifier-block 2 block-number 1 name block_1 set-id 4
