Avaya QoS Manager Overview

 CoS Priority - Avaya switches use only the packets CoS tag. If a

packet entering a module matches no rules, or matches a rule

with a permit operation, the packet will be forwarded with the

priority in the packet's CoS tag.

 Untrust - Avaya QoS Manager ignores both DSCP tags and CoS

priority tags. If a packet entering a module matches no rules, or

matches a rule with a permit operation, the packet will be

forwarded with the default priority.

 Both - Avaya QoS Manager uses DSCP tag and CoS priority tags.

If a packet entering a module matches no rules, or matches a rule

with a permit operation, the packet's DSCP priority (based on

the DSCP Mapping table) and the packet's CoS are compared. The

packet is forwarded with the higher of the two priorities.
