Example: VLAN Rate Limit Hierarchical Policy for Interface Groups Configuration
In this example, three users from a small business office are connected to an E Series
router through the same VLAN interface. The contracted maximum for the business
is 1 Mbps in the upstream direction. The downstream direction is served through
QoS profiles and therefore is not shown here.
Figure 9 on page 138 shows the following:

Example: VLAN Rate Limit Hierarchical Policy for Interface Groups Configuration
ER1-instance-1 is referenced by parent group instance (EPG1, parameter B), and
ER2-instance-2 is referenced by the parent group instance (EPG2, parameter C).
User user_pol1 is attached to the first user's IP interface and does not have a
rate limit.
User user_pol2 is attached the second user's interface and has an individual rate
limit of 300Kbps and preferred voice traffic at 64Kbps.
User user_pol3 is attached to the third user's interface and has some traffic
marked with a low delay (Dsfield = 4), but there are no rate limitations applied.
Policer instance VLAN_RATE is shared across all three instances of EPG1 and
limits the total upstream traffic from three users to 1 Mbps.
Create a rate limit to enforce the contracted maximum for the small business.
Create an external parent group to hold this rate limit.
