Parameter

Description

Values

 

 

 

<access list name>

Access list name

Up to 16 alphanumeric characters.

 

 

 

<COS>

Class of service

 

 

 

 

Mandatory

Number - 0 to 63

 

 

 

 

Example:

The system sets DIFFSERV field to 12 of all the packets that passed access-list video.

Filter-Id = "video out permit 192.168.1.0 255.255.255.0 12", adc-avpair = "qos:cos=video;12"

qos:acl-priority sub attribute

The qos:acl-priority sub-attribute specifies the Q.o.S priority that should be set for an access list within a session. A default access list priority is 0. The system precedes the high priority packets on the low priority ones. The priority is being activated only if the qos:down-mean-rate or/and qos:up-mean-rate are defined for the connected session, otherwise it is being ignore.

Note: If the higher priority traffic is exceeding the session bandwidth limitation, then starvation of lower priority traffic may occur. To prevent lower priority traffic starvation, the higher priority access list bandwidth limitation should be smaller that the session one.
