Manual

You can attach an egress buffer profile to a port.
You must configure the no qos egress-buffer-profile command to detach a profile from any ports that
are using it before you can configure the no qos egress-buffer-profile command to delete it.
The higher the sharing level, the better the port absorb micro-burst. However, higher sharing level of 7
and 8 may compromise QoS functions and create uneven distribution of traffic during congestions.
The following is the default egress buffer profile:
Queue Share level
0 level4-1/9
1 level3-1/16
2 level3-1/16
3 level3-1/16
4 level3-1/16
5 level3-1/16
6 level3-1/16
7 level3-1/16
The following eight queue-share levels are supported:
Level Sharing-pool buffers
level1-1/64 1/64 of buffers in the sharing pool
level2-1/32 1/32 of buffers in the sharing pool
level3-1/16 1/16 of buffers in the sharing pool
level4-1/9 1/9 of buffers in the sharing pool
level5-1/5 1/5 of buffers in the sharing pool
level6-1/3 1/3 of buffers in the sharing pool
level7-1/2 1/2 of buffers in the sharing pool
level8-2/3 2/3 of buffers in the sharing pool
