Provision the Class of Service (CoS) Map

Each layer 2 interface in the Total Access 5000 (Gigabit‐Ethernet, Ethernet, EFM bonding
group, etc.) has four quality of service (QoS) priority queues for traffic egressing the interface.
Traffic is assigned to these queues based upon a Total Access 5000 system‐wide configurable
option. The Total Access 5000 uses the outer 802.1Q VLAN p‐bits to determine to which
queue each Ethernet frame should be assigned. The p‐bits‐to‐queue mapping is done using
the qos cos‐map command. Complete the following procedure:
1. From the Enable prompt, type configure terminal , and press E
2. From the Global Configuration prompt, type qos cos-map <queue_number> <L2 COS
Syntax

L2 COS #n
NOTE
For EoCu services, the Total Access 5000 system pushes the CoS mapping
down to any subtended NetVanta 800 series, so that the mapping applies
uniformily.

Table 3-6. CoS Map Syntax

Definition
The Total Access 5000 queue number (0‐3) to which the L2 CoS
value(s) should be assigned. 0 holds the lowest priority queue, and 3
holds the highest.
All 8 possible values can be specified. This list of CoS/PCP values can
be mapped to the specified QoS queue level.
