Newbie VLAN question


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 (

No matter what I change etc I cannot seem to communicate with the device on VLAN 1 is 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
Untagged Ports      : Gi0/4, Gi0/8, Ex0/2
Name                : Phone
Status              : Static
Egress Ethertype    : 0x8100

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

The ubiquiti is defined as such;


The Ubiquiti is the upstream switch in this case.

Would somebody be kind enough to give me insight.


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?

NET08# show interfaces neighbor

Interface: Gi0/4
Chassis ID:
Port ID: c0:74:ad:80:43:e6
System Name: GXP2130_c0:74:ad:80:43:e6
System Description: GXP2130
Mgmt IPv4 Address:
MAC Address: c0:74:ad:80:43:e6

Interface: Ex0/2
Chassis ID: f4:e2:c6:d0:4b:ad
Port ID: Port 10
System Name: XC-18

MAC Address: f4:e2:c6:d0:4b:ae

Thanks Greg for replying - appreciate it.

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?

NET08# show vlan port Extreme-Ethernet 0/2

VLAN Port Configuration Table
Port Ex0/2
 Port VLAN ID                         : 1
 Port Acceptable Frame Type           : Admit All
 Port Mode                            : Hybrid
 Port-and-Protocol Based Support      : Enabled
 Default Priority                     : 0
 Port Protected Status                : Disabled


The device sees the phone on VLAN 2;

NET08# show mac-address-table vlan 2

Vlan    Mac Address         Type     Ports
----    -----------         ----     -----
2       c0:74:ad:80:43:e6   Learnt   Gi0/4

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.


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.
