Can anyone direct me some good switching documents related to qos to easily break down some of the show statistics to aide troubleshooting on a 6000 platform as in the following example :-
sh qos info run 3/1
un time setting of QoS:
QoS is enabled
Policy Source of port 3/1: Local
Tx port type of port 3/1 : 1p2q2t
Rx port type of port 3/1 : 1p1q4t
Interface type: vlan-based
ACL attached:
The qos trust type is set to untrusted.
Default CoS = 0
Queue and Threshold Mapping for 1p2q2t (tx):
Queue Threshold CoS
----- --------- ---------------
1 1 0 1
1 2 2 3
2 1 4 6
2 2 7
3 - 5
Queue and Threshold Mapping for 1p1q4t (rx):
All packets are mapped to a single queue.
Rx drop thresholds:
Rx drop thresholds are disabled.
Tx drop thresholds:
Tx drop-thresholds feature is not supported for this port type.
Rx WRED thresholds:
WRED feature is not supported for this port type.
Tx WRED thresholds:
Queue # Thresholds - percentage (* abs values)
------- ------------------------------------------
1 40%:70% (124518:217920 bytes) 70%:100% (217907:311168 bytes)
2 40%:70% (26214:45888 bytes) 70%:100% (45875:61440 bytes)
Tx queue size ratio:
Queue # Sizes - percentage (* abs values)
------- -------------------------------------
1 70% (311296 bytes)
2 15% (65536 bytes)
3 15% (65536 bytes)
Rx queue size ratio:
Rx queue size-ratio feature is not supported for this port type.
WRR Configuration of ports with speed 1000Mbps:
Queue # Ratios (* abs values)
------- -------------------------------------
