qos if-assign port 3-6 name unrestricted
12.7.2 ACL Configuration
12.7.2.1 Create ACL’s to Remark DSCP
ERS5500: Step 1 – Create IP-ACL’s
5500(config)#qos ip-acl name pbit ds-field 18 update-1p 3 block pbit
5500(config)#qos ip-acl name pbit ds-field 26 update-1p 4 block pbit
5500(config)#qos ip-acl name pbit ds-field 34 update-1p 5 block pbit
5500(config)#qos ip-acl name pbit drop-action disable
ERS5500: Step 2 – Assign the IP-ACL’s to ports 3-5
5500(config)#qos acl-assign port 3-5 acl-type ip name pbit
12.7.3 Policy Configuration
12.7.3.1 IP Element Configuration
ERS5500: Step 1 – Create IP Classifiers
5500(config)# qos ip-element 1 ds-field 18
5500(config)#qos ip-element 2 ds-field 26
5500(config)#qos ip-element 3 ds-field 34
12.7.3.2 Configure Classifier and Classifier Block
For the classifier block, we will match the following and set the following
IP Element ID Classifier ID Block ID Action ID

2 match DSCP 26 2 Block 1, ID 2 5 – Gold CoS
3 – match DSCP 34 3 Block 1, ID 3 6 – Platinum CoS
ERS5500 Step 1 – Crete a Classifier for each of the IP Element above
5500(config)#qos classifier 1 set-id 1 name c1 element-type ip element-id 1
5500(config)#qos classifier 2 set-id 2 name c2 element-type ip element-id 2
5500(config)#qos classifier 3 set-id 3 name c3 element-type ip element-id 3
ERS5500 Step 1 – Create a Classifier Block
5500(config)# qos classifier-block 1 block-number 1 name b1 set-id 1 in-profile-
