The company I work have finally decided to enter the 21st century and invest in a new telephone system (Interactive Intelligence) to replace the legacy system which has served us well for the past 10 years. The project has only just started and involves upgrading sections of CAT3 cabling to CAT6, replacing Cisco 3550 switches in one area of the building with Cisco 4507 switches and upgrading our Core switches with Cisco Nexus 7010's.
The area that concerns me most is enabling the network for qos as I have very little experience with it. At the moment Im trying to read as much documentation as I can on QOS to bring myself up to speed.
The access layer switches will consist of a mixture of Cisco 3750 & 4507 switches connected to Cisco Nexus 7010 switches which will form a collapsed aggregation & core layer.
Basically I'm after any advice on how I should approach this daunting task of making sure the network will support VOIP.

If my understanding is correct on the input side the RTP traffic is marked by the phone with a dscp value of ef, the policy map then sets the dscp value to 46 and the cos value to 5. The signaling traffic is marked with dscp value of 24. On the output side the policy map matches traffic with dscp value of 46 and places this traffic in the priority queue which is guranteed 33% of the bandwidth. If the RTP traffic exceeds 33% then it is dropped. The signaling traffic is allocated 5% of the remaining traffic using CBWF. All other traffic uses the default class.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
