12.2 Configuration Example 1 – Traffic Meter Using
Policies
Figure 5: Traffic Meter Example
The following CLI commands show how to configure a QoS Polic y 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 followin g TCP flows:
o For UDP dst port 80, m eter traffic at 10M
o For UDP dst port 69, m eter traffic at 5M
o For UDP dst port 137, m eter 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 classif ier block to group all
three classifiers.

At this time, it is only possible to configure traffic meters using pol icies. 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 por t 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 assi gn 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
