Hello,

I have small problem:

I have 3 VLans

1: Vlan 16 is for management

2: Vlan 2 is for Voice

3: Vlan 4 is for desktop

First port I need for management Vlan 16 and left for desktop+voice (Vlan 2 + Vlan 4) and last - gigabit port fot Trunk. Could you help me with configuration? I do not know how to config - Access mode, Trunk, General etc.

Thank you so much.

Hi Mys, what kind of router do you have? Can you give more information about any network equipment that you have?

Hi Tom,

Connection from provider do Cisco 1841 form Cisco 1841 first port to Juniper SRX220 and second port to Asterisk server.

Hi Mys,

For the first port, the port will need to be configured as a trunk port. The native vlan will be 16 (16 untagged) then the vlan 2 and 4 will be tagged. On the GUI the configuration would say 16u, 2t 4t.

To configure this via CLI

config terminal

vlan database

vlan 2,4,16

interface fa1

switchport mode trunk

switchport trunk native vlan 16

switchport trunk allowed vlan add 2

switchport trunk allowed vlan add 4

You made mention of another port but it is not clear what do you want on that port. Do you want to connect a single phone to the port? A single computer? A telephone and computer? The Asterisk box?

Hi Mys, any port using voice vlan + data vlan needs to be configured data vlan untagged, voice vlan tagged.

config t

int fa2

switchport mode trunk

switchport trunk native vlan 4

switchport trunk allowed vlan add 2

I tried it and find out that without native vlan it will not work and once you put native vlan the phone takes the native vlan ip and gives the pc the same ip range.

What I want is that the ip phone will pick voice vlan and give the pc data vlan add.

How do I do the configuration
