Yes you really should. Bandwidth is never an answer to realtime traffic consistency, it's really a question of queue management. You should still use QoS on the gig links. On this laptop I don't have the CCO links handy but there are plenty out there if you do a quick search. The 2950's are different animals than all other switches so you should read their qos configuration guide. I also authored a few a while back I will try and pull out after work tonight. Make sure the 2950's classify the traffic correctly and then just trust DSCP on the gig uplinks to the 6k, no other queuing means are necessary on the gig links. Also make sure you create the correct COS / DSCP maps on the 2950's they don't queue correctly by default for the CCM / Unity apps, but I cannot speak to the soft switch you are using, I only do Cisco Call Manager...

In each IDF I will have atleat (20) 2950 connected to 6500 switch. 6509 then will be connected to 3700 series router for WAN Connectivity. 6509 will also be connected to Nortel CSE1000 IP phone server. The question is: In each branch I will have atleast 5 or 6 IP phones connected to 2950 switch. I Like to put my 2950 switch ports for phones in a different vlan for voice traffic and will have a separate vlan for Data. Do I need any QOS for Voice port? The connection between 2950 switches to 6509 will be Gigabit. I believe I have enough bandwidth between the ports, and voice traffic should be okay w/o any QOS. Is there any specific good link for setup Voice VLAN in 6509 and 2950 switches along with QOS if needed? _______________________________________________ Join Excite! - http://www.excite.com The most personalized portal on the Web!
