12.2Configuration Example 1 – Traffic Meter Using Policies

Figure 5: Traffic Meter Example

The following CLI commands show how to configure a QoS Policy using a Classifier-block with three classifiers and traffic meters. Overall, in this example, we will configure the following:

Setup one Policy with three classifiers metered with the following TCP flows: o For UDP dst port 80, meter traffic at 10M

o For UDP dst port 69, meter traffic at 5M o For UDP dst port 137, meter traffic at 1M

Set the meter bucket size (committed burst) for all meters to maximum value

Add the policy to ports 5 and 6

NOTE: As all three classifiers use the same mask, we will create a classifier block to group all three classifiers.

At this time, it is only possible to configure traffic meters using policies. It is not possible to add traffic meters via ACL’s.

12.2.1 ERS5500 Configuration Using Policies

12.2.1.1 Configure the Interface Role Combination

For this example, we will configure a new role combination with port members 5 and 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 untrusted and assign it to port 5 and 6.

ERS5500 Step 1 – Create the Interface Role Combination and name is “q2”

ERS5500-24T(config)#qos if-group name q2 class untrusted

ERS5500-24T(config)#qos if-assign port 5-6 name q2

12.2.1.2 Configure the IP elements

Configure three IP elements for UDP destination ports 80, 69, and 137.

ERS5500 Step 1 – Create the IP elements

ERS5500-24T(config)#qos ip-element 1 addr-type ipv4 protocol 17 dst-port-min 80 dst-port-max 80
