Configure a traffic class at the policy level

Note: Within the scheduling hierarchy, you can configure traffic classes at both the policy (shaper) level and at the profile level.

Note: You apply a traffic class configuration globally, per profile.

At the policy level you can configure each traffic class with an aggregate bandwidth and a queue limit for all the profile queues that are assigned to each traffic class.

Configure the traffic class to have a specific bandwidth.

user@system# set policy qos name policy-1 shaper traffic-class 1 bandwidth 300kbit

Define the maximum length of the queue.
For hardware platforms, define this as the maximum number of bytes that packets on the queue can consume:
```
user@system# set policy qos name policy-1 shaper traffic-class 1 queue-limit-bytes 100000
```
For software platforms, define this as the maximum number of packets on the queue:
```
user@system# set policy qos name policy-1 shaper traffic-class 1 queue-limit 128
```
Commit the configuration.
```
user@system# commit
```

You have configured your traffic class at the policy level.
