ATA 192 bridge mode

[Cyrus777]

We have a few offices that we need to have ATA and printer connected to the same switch port on Meraki MS. The port is configured in access mode and allows traffic for VLAN x (data) and VLAN y (Voice). we have the ATA connected to switch port and using the LAN port on the ATA we connect the printer. (ATA must act as a switch to provide network access for printer like an IP phone). Printer has static IP on data VLAN and ATA gets a dynamic IP from DHCP on voice VLAN. the ATA is set to bridge mode.

with this setup printer communication is totally lost and ATA does not pass the traffic for data vlan over the built-in switch on the device. If I remove the voice vlan config on the MS port and only have Data VLAN in the config, then both devices are on the same VLAN and the traffic can pass through the ATA built-in switch and they both are happy. The problem is that ATA does not pass the traffic with Data vlan tag if the ATA itself is on voice VLAN.

Any idea what must be done on ATA or anywhere else to make this work properly and separate the traffic for printer and ATA on their own VLANs?

One thing that you can try is instead of configuring the switch port as an access port, configure it as a trunk port an set the native VLAN to the data VLAN and allow the voice VLAN as tagged traffic.

ATAs are, in my experience, notorious with not doing things right with VLANs and we usually end up putting them in access mode on the voice vlan with the actual voice vlan setting blank. I know that doesn't help your situation but at a certain point a separate drop could be a solution.

Lot more folks who use Cisco telephony products over there. In general the issues I see are switch agnostic. Could just be a firmware update needed.

@Mloraditch is right here, the ATA192 needs to be connected to the voice VLAN by using an access port in that VLAN.  The printer will need a different connection, or if you have a pair of cable splitter apadters you can make two 2-pair cables from the one 4-pair feed.

In my experience, you won't be able to get the printer on a different VLAN to the native ATA function.

Going sideways; does the printer by chance have WiFi built in?

[Cyrus777]

no. that is another issue
