2920-24 x 2 Stacked CORE + 2530-48 as Edge Data&Lync) & Zxyel POE Swtchs for VOIP Handsets

Hi All

 

We are relatively familiar with procurve switches but need help on a particualr confg needed which is dictated by a VOIP provider who has requested a particular set of instructions for a new Data network we have been asked to provide (they are doing the VOIP config using their Zxyel Switches)

 

Our Core is 2x2920's stacked and will feed 2 x Zxyel switches and 4 x 2530-48 switches.

The core will also feed HP Servers using LACP for each server having dual nics balanced across the two individual 2920's and the company's SONICWALL FIREWALL for Internet Connection.

The Zxyel switches are ONLY going to be used for phyiscal VOIP SIP Handsets

The 2530-48's will be used for PCs/printers etc AND these pcs will have MS LYNC.

ROUTING IS TO BE DONE ON THE CORE SWITCHES (NOT THE FIREWALL).

 

The only instruction we have been given are :

 

1.To ensure our new DATA NETWORK has VLANS and subnets that are provided DHCP IP addresses from a central server giving out separate IP subnets all working through one Internet Sonicwall Firewall.

2. The HP core switches will need to be configured to support DSCP for QoS if they aren’t already with DSCP value 46 (voice) going into the EF queue and DSCP value 34 (video) going into a best efforts queue. 

3. They will provide 2 Zxyel Switches for SIP Handsets (no PCs will connect to these switches

4. The Desktop PCs will run MS LYNC which they will configure to use DSCP 46 for Voice and DHCP 34 for Video via GPO.

 

We have NO SIP system to test with so are building this configuration in a TEST LAB and need to have it ready meeting the above needs, of which the primary concern is item 2 (DSCP 46 and 34).   But we have the kit and have got things configured as follows.

 

We've created a number of VLANS.   VLAN10 the data network will also be the management VLAN for us to access all switches.  It will also host the servers and client pcs. 

VLAN20 will be voice.

 

So based on our understanding,

 

1. we have assumed ANYTHING plugged into the ZXyel won't need any special QoS because it is only going to be used for SIP and our config proves that any port on the Zxyel ONLY gets a VLAN 20 Ipsubnet for voice.

 

2. ANYTHING on VLAN10 needs to get 192.168.10.x BUT if that device is a PC running LYNC, it has to have a higher priority for Voice and Video being routed out to the INTERNET on within the VLAN for PC to PC Lyncing inside or outside.

 

Our core config is as follows:

1. Based on the requirement and our understanding which may be wrong, our thoughts are the VLAN10 needs to have DSCP 46 for LYNC voice and DSCP34 for LYNC video.   When we add the second command it overwrites the first.  ? What do we need to do

 

2. Are our QoS and VOICE commands correct ?

3. DO you feel we need to allow any other general config commands. 

4. We haven't been explicitly told to NOT allow Intervlan routing; phones on VLAN20 on the Zxyel Switches will get an IP address from our win2008 server and go straight out for SIP connection to the hosted PBX. - On this basis we know a laptop on VLAN 10 and ping a laptop on VLAN20 and vice versa

5. SHOULD WE REMOVE THE STATIC ROUTE AND USE RIP ROUTING.  IF thats the case what do we change to both configs

6. We have added the DSCP 46 command to VLAN20 - is this needed if nothing else is going to be plugged in ?

7. Is it advised we do anything to do with Multicast ?

 

Hoping some people can help guide us to refine this configuration.

 

Oh, is there any way of actually TESTING - SATISFYING oneself that QoS is working on say the Data VLAN?

 

Thank you in advance.
