12.4.1 Configuration – Using Policies
12.4.1.1 Configure the Interface Role Combination
For this example, we will configure a new role combination with port members 3 to 6. You have
the choice of assigning a policy directly at a port level or using an interface role.
By default, all ports are set for untrusted using the allBayStacklfcs Role Combination. In this
example, we will configure a new Role Combination as unrestricted and assign it to port 3 to 6.
ERS5500 Step 1 – Create the Interface Role Combination and name is “ifx”
ERS5500-24T(config)# qos if-group name ifx class unrestricted
ERS5500-24T(config)#qos if-assign port 3-6 name ifx
12.4.1.2 Add new IP element pertaining to the port ranges above
ERS5500: Step 1 – Create IP elements for TCP port range 80-127
5500(config)#qos ip-element 1 protocol 6 dst-port-min 80 dst-port-max 95
5500(config)#qos ip-element 2 protocol 6 dst-port-min 96 dst-port-max 127
ERS5500: Step 1 – Create IP elements for UDP port range 2000-2027
5500(config)#qos ip-element 3 protocol 17 dst-port-min 2000 dst-port-max 2015
5500(config)#qos ip-element 4 protocol 17 dst-port-min 2016 dst-port-max 2047
12.4.1.3 Configure Classifiers, one for each of the IP elements configured above
ERS5500 Step 1 – Create the an IP Classifier for each IP element created 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
5500(config)#qos classifier 4 set-id 4 name c4 element-type ip element-id 4
12.4.1.4 Configure the Policies
Create the policies with the classifiers created above. Please refer to table 3 in reference to the
policy action.
ERS5500 Step 1 – Create the policy
5500(config)#qos policy 1 name range_tcp_1 if-group ifx clfr-type classifier
clfr-id 1 in-profile-action 5 non-match-action 9 precedence 11
5500(config)#qos policy 2 name range_tcp_2 if-group ifx clfr-type classifier
clfr-id 2 in-profile-action 5 non-match-action 9 precedence 10
5500(config)#qos policy 3 name range_udp_1 if-group ifx clfr-type classifier
clfr-id 3 in-profile-action 4 non-match-action 9 precedence 9
5500(config)#qos policy 4 name range_udp_2 if-group ifx clfr-type classifier
clfr-id 4 in-profile-action 4 non-match-action 3 precedence 8
