Hello,

I've recently seen a Cisco qos configuration for non-Cisco IP Telephony that does not define a queueing strategy or priority queuing.

On access switches, it simply implements "mls qos" and marking using policy maps. No priority queuing or anything.

Seems to work fine, but I don't think it's right.

If you don't specify a queuing strategy (WRR or SRR) doesn't this actually slow down the traffic ?

Will it still use all the queues that "mls qos" generates ?

Is there some form of basic queuing (FIFO ??) and how do I see what it is ?

I usually use AutoQoS to do this for me, so I've never seen a config without the queuing.

Anyone have any thoughts to this design ?
 

Thanks
Thomas
