Chapter 12 Configuring Quality of Service on the ML-Series Card

ML-Series Egress Bandwidth Example

For example, if 18x bandwidth is available after servicing priority unicast traffic (CoS 5), then the remaining bandwidth will be allocated as follows:

Unicast traffic with CoS 2 : 2x

Unicast traffic with CoS 7: 6x

Unicast default (without CoS 2, CoS 5, CoS 7): 9x

All multicast/broadcast (any CoS value): 1x

Example 12-14 QoS with Priority and Bandwidth Configured without Priority Multicast

class-map match-all customer_voice match cos 5

class-map match-all customer_data match cos 7

Case 2: QoS with Priority and Bandwidth Configured with Priority Multicast

In this case, only multicast traffic of CoS 3 is allocated a guaranteed bandwidth. This multicast traffic will now participate in the queue along with other WRR queues. After servicing the

traffic, the remaining interface bandwidth is utilized for WRR queues, such as customer_core_traffic, customer_data, class-default, and multicast CoS 3 traffic in the ratio of 1:3:5:2.

At any given time, the sum of the bandwidth assigned cannot exceed the interface bandwidth (in kbps).

Example 12-15 QoS with Priority and Bandwidth configured with Priority Multicast
