Summary
Having innovaphone IP phones, different Vlan´s (IEEE 802.1Q) and Pc´s connected behind the innovaphone IP phones.
Applies To
This information applies to
- IP110
- IP200
- IP230
More Information
The IP110, IP200, IP230, can handle Vlan Tags
Problem Details
Voice and Data Vlan on one switch port – when you are connected to a Switch with an IP Phone and on the IP Phone switch port is a PC connected.
System Requirements
Switch has to support tagged and untagged Frames on one Port. ===Installation Configure the same Vlan Id on the Phone as on the Switch.
Configuration
You can configure a Vlan tag on these phones- the phone will send every frame with this configured tag. (Tagged frames)
Now you have Pc´s connected behind these phones (via the phone switch port) - this Pc should be in a different Vlan (for Qos and security reasons- different Ip Subnets, different Dhcp servers,...)
The switch must support tagged and untagged frames on one port!
So the tagged frames are the voice Vlan (you have to configure the same Vlan id on the switch as on the phone)
The switch put every frame from the IP phone in the configured Vlan.
So all phones and the innovaphone PBX should be in this Vlan (that’s nice because the innovaphone PBX can then be also dhcp server only for the phones.
The Pc data should send untagged frames
When untagged frames are send from the Pc - the switch put it in his default Vlan (or port based Vlan, or untagged Vlan)
You have now two different networks (Vlans) on one port.
If you configure your whole local network like this- you can connect your phone to every switch port and you are always in the right Vlan.
