srr-queue bandwidth shape. how to see if it works ?

When a port is configured with:

Switch(config)# interface gigabitethernet0/1

Switch(config-if)# srr-queue bandwidth shape 8 0 0 0

Switch(config-if)# srr-queue bandwidth share 4 4 4 4

The bandwidth in queue 1 is shaped and limited to 8%

On a switch, how do i see if a port has already dropped packets in queue 1.

How do i detect that my queue1 is really full and the switch is dropping (or shaping) packets actively ?

mvg,

Geert

The bandwidth in queue 1 is shaped and limited to 8%

Not 8% but 1/8 or 12.5% of the interface bandwidth.
