<DIV><BR></DIV><BR><FONT face=sans-serif size=2>I know this is going to open a
whole long discussion BUT</FONT> <BR><BR><FONT face=sans-serif size=2>Is
having your phone traffic seperated really needed. Is QOS on a LAN
really actually needed. I mean come on we all have atleast gig uplinks I
want to see where the buffers on the switch get full enough to slow down
traffic over the 20ms jitter buffer on a local LAN segment or drop
packets.</FONT> <BR><BR><FONT face=sans-serif size=2>Now over the WAN thats
somewhere that QOS definatly needs to be involved.</FONT> <BR><BR><FONT

customer just posed a question to me and I couldn't find anything on
google.</FONT> <BR><BR><FONT size=1>Are there any interoperability issue with
using Nortel LAN switches with Cisco IP Phones. The CIO for this customer is
looking to save some $ by using non-cisco ip phones. </FONT>
<BR><BR><FONT size=1>My first thoughts were that the Cisco switch provides two
things, power and voice vlan support. The nortel switches do support 802.3af
so power should not be an issue. But since CDP is a cisco proprietary
protocol, the nortel switches won't support CDP which means that the phones
will not automatically use the voice vlan for voice traffic. This just means
that the customer would have to do something else to segregate and QoS the
voice traffic such as an acl.</FONT> <BR><BR><FONT size=1>Are there any other
considerations?</FONT> <BR><BR><BR><FONT size=1>tm</FONT> <BR><FONT
