Command Types Switch command.
Command Modes Privileged.
Usage Guidelines If you enter the set qos map port_type tx | rx q# cos coslist command, the following is a list of possible
port types available:
•tx port_type = 1p3q1t and 1p2q1t
•rx port_type = 1p1q0t and 2q8t
You can enter the cos_list variable as a single CoS value, multiple noncontiguous CoS values, a range
of CoS values, or a mix of values. For ex ampl e, yo u ca n ent er an y of the following: 0, or 0,2,3, or 0-3,7.
The priority queue number is 4 for transmit and queue number 2 for receive.
When specifying the priority queue for the 1p2q2t port type, the priority queue number is 3 and the
threshold number is 1.
The receive- and transmit-drop thresholds have this relationship:
•Receive-queue 1 (standard) threshold 1 = transmit-queue 1 (standard low priority) threshold 1
•Receive-queue 1 (standard) threshold 2 = transmit-queue 1 (standard low priority) threshold 2
•Receive-queue 1 (standard) threshold 3 = transmit-queue 2 (standard h ig h pri or ity) th reshol d 1
•Receive-queue 1 (standard) threshold 4 = transmit-queue 2 (standard h ig h pri or ity) th reshol d 2
Refer to the Catalyst 6500 Series Switch Software Configuration Guide for additional usage guidelines.
Examples This example shows how to assign the CoS values 1, 2, and 5 to the first queue and the first drop
threshold in that queue:
Console> (enable) set qos map 2q2t tx 1 1 cos 1,2,5
Qos tx priority queue and threshold mapped to cos successfully.
Console> (enable)
This example shows how to assign the CoS values to queue 1 and threshold 2 in that queue:
Console> (enable) set qos map 2q2t tx 1 2 cos 3-4,7
Qos tx priority queue and threshold mapped to cos successfully.
Console> (enable)
