RE: [WISPA] Switch Recomendation
Surely, unless the bandwidth at the switch port is a bottle neck then traffic will not get buffered/queued on the switch and QoS will not come into play?? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of John J.

Re: [WISPA] Switch Recomendation
Actually, no. Really, all a QoS enabled device can do is create an access list that looks for specific TCP/IP connections and mangles the TOS bit on the packets. So again, you don't need a QoS enabled device; you just need your VoIP devices to go ahead and set the TOS bit, so your layer 3 device can do the right thing. BTW, outside of setting the TOS bit, you can use to 802.1Q/802.1P assuming your VoIP device is VLAN-enabled and your network devices are VLAN aware. The VLAN route is really the way to go, but most radios aren't up for it. We have found Canopy to do quite well with VLANs and even maintains a separate VC for high priority VLANs. Of course the CMM is not VLAN aware, which is a bummer. Just to recap, we use Cisco 6500s and Cisco 3750MEs for our entire network, but we don't have to maintain a single access list on them for VoIP since our VoIP PBX/ATA/phones all know about TOS, and 802.1P. -Matt Rick Smith wrote: I can't see how having a QOS switch could hurt...with VOIP, QOS in as many places as possible can only help...

We have been real happy with the HP ProCurve series of switches. The 2512 would probably do what you are looking for. Fully managed, qos, 4.8 mpps and lifetime warranty.
