Please note that protocol 17 = UDP.
12.2.1.3 Configure three Classifiers, one for each of the IP elements configured above
ERS5500 Step 1 – Create the an IP Classifier for each IP element created above
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 step above
12.2.1.4 Configure Meters
As mentioned in section 5.2 above, if we do not configure a maximum 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 committed-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 following
• 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
