Filters and QoS Configuration for ERS 5500

NN48500-559

12.6 Configuration Example 5 – L2 and L3 Classification

In this configuration example, the Ethernet Routing Switch is used as L2 switch with two VLANs providing L2 private VLAN services. Both VLAN’s have the same over-lapping IP addresses where workstation 1 and 2 are used to provide high-touch services. Overall, we wish to accomplish the following tasks:

Setup a policy to provide Gold service for host 1 and Silver service for host 2

For all other non-match traffic, set the default service class to Bronze service.

Figure 8: L2 and L3 Classification Example

The best way to accomplish these tasks is to:

Create a Role Combination for port 1/3

Create the first classifiers element with host 1’s IP address and VLAN 110 and add to Classifier Block 1 with an in-profile action of Gold Service

Create a second classifier element with host 2’s IP address and VLAN 120 and add to Classifier Block 1 with an in-profile action of Silver Service

Create a Policy with Classifier block 1 and the Role Combination for port 1/3 with a non- match action of Bronze Service

At this time, it is only possible to combine L2 and L3 filters using policies. It is not possible to combine IP-ACL’s with L2-ACL’s.

12.6.1 ERS5500 Configuration – Using Policies

12.6.1.1 Create a Separate Role Combination for Port 1/3

ERS5500 Step 1 – Add new role combination for port 1/3 configured as untrusted and add port member 1/3

ERS5500-24T(config)#qos if-group name Int_group_2 class untrustted

ERS5500-24T(config)#qos if-assign port 1/3 name Int_group_2

12.6.1.2 Add IP and L2 Classifiers Elements

ERS5500: Step 1 – Add IP elements with source address of 192.1.1.10

5500(config)#qos ip-element 1 src-ip 192.1.1.10/32
