Adding a second range. 1 Domain 2 for VOIP & CCTV

[speckytecky]

We currently have DHCP allocated to our Domain through our DC. We have now been allocated a second IP Address range to use for VOIP & CCTV. As DHCP allocation is not something I'm dealing with day to day (it usually just about runs itself) I'm seeking advice on how to allocate the New range to the PoE Switches that have been set up to run the CCTV / VOIP. What's best practice please.

What do you folk use for Network address translation?

Is your network connected to an LA? Or do you have your own internet connection? Do you have a managed core switch?

 

NAT is used to change IP addresses. The best example is on an internet connection, it converts the private addresses (192.x.x.x. or 10.x.x.x or 172.x.x.x) into the public IP.

Thanks @FN-GM as ever you are spot on. No not the LA SWGfL FFTC. We do have a HP Procurve.

What you would need to do is create a new VLAN. If give it an ip address so it would route to your existing VLAN. However its hard to tell what work needs to be carried out. Can you post a config of your core switch?

 

Im not very experienced with HP switches, I do Cisco myself so help from someone else maybe required.

I've installed quite a few large HP networks.

 

Would need more info but some config examples below:

 

vlan 13

name schoolname_cctv

ip address 10.0.13.254 255.255.255.0

ip helper-address 10.0.10.1

tagged A1-A24

 

vlan 14

name schoolname_voip

ip address 10.0.14.254 255.255.255.0

ip helper-address 10.0.10.1

qos priority 6
