12.2.1.3 Configure three Classifiers, one for each of the IP elements configu red above

ERS5500 Step 1 – Create the an IP Classifier for each IP element created ab ove

ERS5500-24T(config)#qos classifier 1 set-id 1 name c1 element-type ip element-

id 1

ERS5500-24T(config)#qos classifier 2 set-id 2 name c2 element-type ip element-

id 2

ERS5500-24T(config)#qos classifier 3 set-id 3 name c3 element-type ip element-

id 3

L

The element-id = the element number you assigned in the previous ste p above

12.2.1.4 Configure Meters

As mentioned in section 5.2 above, if we do not configure a maxim um duration rate, the

committed burst will be automatically set to the maximum value. For all 10/100 Mbps and 1 GigE

Ethernet ports, the maximum committed burst is 524,288 bytes. Hence, it does not matter what

value you enter for the max-burst-rate as long is it is greater than the c ommitted-rate.

ERS5500 Step 1 – Create the QoS meters: “m1” with 10M, “m2” with 5M , and “m3” with

1M

ERS5500-24T(config)#qos meter 1 name m1 committed-rate 10000 max-burst-rate

11000 in-profile-action 2 out-profile-action 1

ERS5500-24T(config)#qos meter 2 name m2 committed-rate 5000 max-burst-rate 6000

in-profile-action 2 out-profile-action 1

ERS5500-24T(config)#qos meter 3 name m3 committed-rate 1000 max-burst-rate 2000

in-profile-action 2 out-profile-action 1

12.2.1.5 Configure the Classifier Block

For this example, we will create a classifier block named “b1” with the f ollowing

• ID 1 with Classifier element 1 and meter 1

• ID 2 with classifier element 2 and meter 2

• ID 3 with classifier element 3 and meter 3

ERS5500 Step 1 – Create the classifier block

ERS5500-24T(config)#qos classifier-block 1 block-number 1 name b1 set-id 1

meter 1

ERS5500-24T(config)#qos classifier-block 2 block-number 1 name b1 set-id 2
