T is for threshold. 3560's allow threshold configurations (drop thresholds)
in the srr-queue configuration techniques. The 3550 does not allow any
threshold configuration.

When you get into higher-end switches (6500, etc.) you have all sorts of
varieties depending on the module used.

Subject: Interpreting QoS capabilities

Hello,

I'm having problems interpreting a switches QoS capabilities:

show interfaces capabilities on my 3550 shows:

QOS scheduling: rx-(1q0t),tx-(4q0t),tx-(1p3q0t)

I assume p=priority and q= software queues but what is t ?

Why are two tx values ?

Can someone sched any light on this ?

Thanks, Thomas
