Yes you have to go for a VLAN.Vlans are the means of logical isloation at layer2.In case of a physical isolation you would require a separate switch that will uplink to the coore and you have to do the inter-valn routing for communication among the diff vlans. Here just create the vlan on the switch and assign the respective phone ports to the vlan and this will solve your purpose.
You can definitely create VLANs, but need to take care of some things here.. Since you are saying , it works on layer 2, and if u dont assign an IP on layer 3, this phone will not cross the VLAN boundary.. if the IP PBX or the IP phone server is on a different VLAN, then u will have issues.. All the required components should be in the same broadcast domain for these phones to work fine, since all the components are in layer 2 VLANs..
Also, you can have the management IP on any VLAN and assign the phone an IP addrss. since this is on layer 3, this will be reached from outside.. but on a single port, u can define only one data VLAN... so, u can configure the layer 2 IP phone VLAN as voice VLANs and the management VLAN as the data VLAN for that switchport.. This is how we normally do it on the IP telephony solution of Cisco...
Hope this helps.. all the best. rate replies if found useful..
Forgive me because I am not sure I understand here.
The NBX phones are all layer 2 devices and I am only concerned with isolating them from the rest of the network.
Are you saying that even though the phones are a layer 2 device, I will still have to give the VLAN I create for them on the Cisco switches an IP address? Even though the phones themselves will not use this address?
Also, I am a little confused by this:
"but on a single port, u can define only one data VLAN... so, u can configure the layer 2 IP phone VLAN as voice VLANs and the management VLAN as the data VLAN for that switchport.. This is how we normally do it on the IP telephony solution of Cisco... "
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
