12.5 Configuration Example 4 – L2 Classification Based
on MAC Address
In this configuration example, we wish to set the service class for any MAC address from
00:00:0A:00:00:00 to 00:00:0A:00:00:ff to a Service Class of Gold and all other traffic with a
Service Class of Bronze. This in effect will change the 802.1p value to 4, if the port is set for
tagged, and also set the DSCP value to AF31 (0x1A).

12.5.1 ERS5500 Configuration – Using Policies
12.5.1.1 Configure the Interface Role Combination
ERS5500 Step 1 – Create the Interface Role Combination and name is “vlan_110”
ERS5500-24T(config)#qos if-group name vlan_110 class unrestricted
ERS5500-24T(config)#qos if-assign port 1/3-4 name vlan_110
12.5.1.2 Add new L2 element
ERS5500: Step 1 – Add an L2 element for VLAN 110 and specify MAC address
5500(config)#qos l2-element 1 src-mac 00:00:0a:00:00:00 src-mac-mask
ff:ff:ff:ff:ff:00 ethertype 0x800
12.5.1.3 Configure Classifier
ERS5500 Step 1 – The following steps add the L2 element created above to an L2
classifier element
5500(config)#qos classifier 1 set-id 1 name c1 element-type l2 element-id 1
12.5.1.4 Create Policy
Create the policies with the classifiers created above. Please refer to table 3 in reference to the
policy action.
ERS5500 Step 1 – Add policy for L2 classifier created above and apply it to role
combination vlan_110 with an in-profile action of service class Gold and non-match action
of service class bronze
5500(config)# qos policy 1 name "pol_1" if-group "vlan_110" clfr-type classifier
