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

The following eight queue-share levels are supported:

1/64 of buffers in the sharing pool

level2-1/32
