Newbie VLAN question

Hi,

I’m hoping somebody could give me some insight into integrating a Ubiquiti USW switch with a Cambium TX1012-P-DC.

I have a telephone connected to the TX on Port 4 on VLAN 2 (192.168.42.0/24)

No matter what I change etc I cannot seem to communicate with the device on 192.168.42.68. VLAN 1 is 192.168.1.0/24 and VLAN 3 is another subnet.

My TX is configured as such;

VLAN Database
-------------
VLAN ID             : 1
Member Ports        : Gi0/1, Gi0/2, Gi0/3, Gi0/5, Gi0/6, Ex0/1
                      Ex0/2, Ex0/3, Ex0/4
Untagged Ports      : Gi0/1, Gi0/2, Gi0/3, Gi0/5, Gi0/6, Ex0/1
                      Ex0/2, Ex0/3, Ex0/4
Name                : control
Status              : Static
Egress Ethertype    : 0x8100
----------------------------------------------------
VLAN ID             : 2
Member Ports        : Gi0/4, Gi0/5, Gi0/8, Ex0/1, Ex0/2, Ex0/3
                      Ex0/4
Untagged Ports      : Gi0/4, Gi0/8, Ex0/2
Name                : Phone
Status              : Static
Egress Ethertype    : 0x8100

My Ubiquiti is configured as 192.168.1.0/24 is the Default and all traffic is tagged.

The ubiquiti is defined as such;

switch.vlan.1.id=1
switch.vlan.1.mode=untagged
switch.vlan.1.status=enabled
switch.vlan.2.id=2
switch.vlan.2.mode=tagged
switch.vlan.2.status=enabled
switch.vlan.3.id=3
switch.vlan.3.mode=tagged
switch.vlan.3.status=enabled

...

The Ubiquiti is the upstream switch in this case.

Would somebody be kind enough to give me insight.

Thanks
Chris

Which port on your Cambium TX switch is your uplink port to the Ubiquiti switch? Also, what are you PVID settings for each port on your TX switch?

On the Cambium TX switch the ex/02 interface needs to be tagged for VLAN 2 to match how you have the Ubiquiti configured.

Would you mind giving me SSH script to do this? It would help me understand better.

I’m assuming you’re referring to this config?

The device sees the phone on VLAN 2;

I would recommend doing the switch configuration in the management system (cnMaestro or XMS-Cloud) but if the switch is not in a management system, then recommend using the Web UI and configuring as below.

Hi @CHRISTOPHER_NEIL_EDW

We have addressed this query on call today:

We created VLANs 2 and 3 on the top Cambium switch. The port connecting to the Ubiquiti switch was configured as a trunk port to allow traffic from these VLANs.

On the Ubiquiti Switch, the trunk port connecting to the top Cambium switch was verified to ensure it permits VLANs 2 and 3.

On the bottom Cambium Switch, a trunk port towards the Ubiquiti switch was configured. The port connecting to the IP Phone was configured as a hybrid port with VLAN 2 assigned.

Following these configuration changes, the IP Phone’s connectivity was confirmed. Please let us know if you have any other questions.

I recommend to enable voice-vlan on VLAN 2 rather than static configuration. The witch will automatically assign vlan 2 to any port where the ip phone is detected. Voice-vlan also configures the port to prioritize voice traffic and inform the ip phone via LLDP-MED to use vlan 2 tag for voice.
