First off it's PBX not pabx.
There is a lot of missing info. Is your router plugged into this switch? Is the router have vlan 3 configured? Are the phones sharing data ports with PCs or do the phones have their own switch? Are PCs being plugged into the PC port on your VoiP phones?
The setup is isp > load balancer > juniper firewall > hpe switch
The pbx is connected to hpe switch. The phones is sharing data port with pc. Meaning data vlan and voice vlan should be together.
I want vlan 1 as data vlan and vlan 3 as my voice vlan.
You are making it far far far more complicated than it needs to be.
Hire a professional.
How is this complicated when it is a normal setup at every place i have been thru
Ok so this is helps.
Create Vlan 3 on router and set it to DHCP server so it hands out IPs. Set the range to exclude the IP address you are going to give the PBX system PBX system will need itself configured to use Vlan tag 3. If Vlan 3 is going to go through the same interface as your data interface the firewall needs that configured so data is native lan. If the HPE switch is having data and voice go through the same interface you need to set that port as a trunk and allow Vlan 1 for native data and 3 for voice. Trunk ports allow multiple vlans through them while access ports dont. So really if every port on the switch that will share voice and data all need to be trunked for Vlan 1 and 3. Next phones will need to manually have vlan 3 set on them to get a DHCP address and communicate on Vlan 3.
The dhcp is from juniper firewall. So no need to declare voice vlan ? Just trunk vlan 1 and 3 and manually set vlan 3 on each phone ? This is what you trying to say correct ?
the switch will have default vlan 1 and tagged vlan 3 on all ports that have phones connected.
the router will have to be configured for a tagged vlan 3
the pbx, you have two options set the port The phone system connects to to a access port to vlan3 or set the pbx to vlan3
hope it helps
Meaning i dont have to declare voice vlan 3 ? Just put tagged vlan 3 is enough from what you said correct ?
I want data vlan 1 and voice vlan 3. How to make sure my pc is getting default vlan while my phone is on vlan 3 (or voice vlan 3) ?
basically yes, the voice vlan priorities the voice traffic, so you create the Vlan and tell the switch vlan 3 is voice ( this may differ on the hpe switch you have )
Understood. So from this article i just need to declare vlan 3 qos priority 7.
So the command will be : -
vlan 3 tagged
vlan 1 untagged (i believe this will not be shown in the show config)
Correct me if im wrong.
a switch in default all port are on vlan 1 untagged.
you need to tell the switch which ports have vlan 3 assigned as a tagged vlan.
if you use a show ports membership, you will see vlan 1 and tagged vlan3
hope it helps
Understood thank you for your advice. Will try this method later.
