SROS Command Line Interface Reference Guide
Functional Notes
QoS policies are configured in the SROS CLI to dictate the priority for servicing specified traffic types on a
particular interface. QoS policies contain at least one match reference (using the match command) and
one or more action items (using the priority, bandwidth, or set commands).
The match command specifies the criteria used when determining whether incoming traffic is a candidate
for the QoS policy action items. Multiple match statements can exist within the same QoS policy, allowing
a single QoS policy to service various types of traffic.
Note
Each listed match statement is handled independently by the processor. Entering too many
match statements in a QoS policy can burden the processor.
For example, consider a network that contains Class A and Class B traffic that each require 25% of the
total allocated interface bandwidth.
ProCurve(config)#qos map MyMap 1
(
ProCurve config-qos-map)#match list Class_A
(
ProCurve config-qos-map)#match list Class_B
(
ProCurve config-qos-map)#bandwidth percent 25
Alternately, the following configuration is also valid:
ProCurve(config)#qos map MyMap 1
(
ProCurve config-qos-map)#match list Class_A
(
ProCurve config-qos-map)#bandwidth percent 25
ProCurve(config)#qos map MyMap 2
(
ProCurve config-qos-map)#match list Class_B
ProCurve(config-qos-map)#bandwidth percent 25
To remove a configured match statement, enter the entire match statement with a preceding no. For
example, to remove the match statements from the above configured QoS map:
ProCurve(config)#qos map MyMap 1
(
ProCurve config-qos-map)#no match list Class_A
and
ProCurve(config)#qos map MyMap 2
(
ProCurve config-qos-map)#no match list Class_B
Usage Examples
The following example configures QoS for a network with the following needs:
Reserve 15% of the line rate for routing traffic and L2 protocol traffic (max-reserved-bandwidth = 85)
Line Rate = 512 kbps
