QoS differences between 3750X and 2960S platforms

[lcaruso]

Hi,

We are looking to replace some aging 3560 switches with 100Mb/s interfaces. They service IP phones and workstations.

For having IP phones directly connected to access switches that are also  servicing workstations, we don't need L3 routing except in the core, so  the question is what would we lose if we used 2960S switches for access  switches.

I understand from having spoken with Cisco TAC that a limited subset of QoS is available on the 2960S platform. Can anyone tell me if that includes the priority queue that is enabled when you turn on mls qos on a L3 switch?

Thanks.

PQ is supported on 2960, however like a 3750X beside enabling QoS, you need to specify PQ per port.

Good place to see capabilities of 2960 series for QoS, is their configuration guides (e.g. http://www.cisco.com/en/US/docs/switches/lan/catalyst2960/software/release/15.0_2_se/configuration/guide/swqos.html).
