Is the Cisco 2948G-L3 switch a good switch for bandwidth shaping?

I'm considering putting two stacked 2948G-L3 switches as our core network switches.  My core need for these switches (other than to replace some ancient switches we have) is for QoS support.  I need to be able to effectively shape bandwidth to the internet.  I want internet bound calls to run fast when it's available but not to hog all of our avaiilable internet bandwidth, so I want to guarantee a minimum bandwidth to each port (knowing that not everyone is going to hit the internet at once).

Is this unit fully capable of this?  The link below seems to imply that it is.  I can pickup to used switches at very reasonable prices.  Any reasons for not doing this or for looking for used equipment with any minimum firmware version?

Thank you.

Used to have many of these switches in our cabs. They are fantastic workhorse switches with the added bonus of layer 3, However, you can only do little in terms of QOS, Traffic shape rate, is probably the most it can do.

Hope this helps.

Iklamar,

  Thank you for the link.  In this shaping: (1)  Is it possible to only shape port 80 traffic?  (1) Is it possible to only shape port 80 traffic going outside of the local network (ie. to the internet?).

Thank you.

it seems that you only shape only the interface, port shaping not possible
