Voice VLAN

RouterOS General
1

We have just acquired a company that has Cisco switch with Auto Voice VLAN enabled on VLAN10. I was able to program a RB1100AHx4 to accept this VLAN configuration. Now I am working on the moving from the Cisco switches and replacing them with Mikrotik switches. Let me give you a quick rundown of the current setup.

There are 3 buildings

Building 1

RB100AHx4 with VLAN10 configured to a separate network segment
Single cable leaving the router on the lan side going to the Cisco switch which is is automatically tagging vendor specific voip phones to route over the VLAN and computers go to the default bridge

Building 2
Fiber cable running from the Cisco switch in Building 1 to building 2 to another Cisco switch with the same auto voice VLAN enable tagging phones only so the VOIP goes to the VLAN on the router and computers go to the bridge interface

Building 3
Mikrotik Point to Point plugged into the Cisco switch in building 2 with the same cenario with computers in bridge and the VOIP getting auto tagged from the switch in building 2

Cisco seems to do a vendor specific filter for the VOIP using a wildcard. In this instance it is finding any mac that starts with 64:16:7F for Polycom phones and routes them to the VLAN

I would like to replace both of the switches in building 1 & 2 with a CRS Mikrotik switch

Is there any way to setup Auto-Voice VLAN in mikrotik switches to function in the same manner as Cisco using Vendor MAC codes?

I see an option to input the entire MAC address under SWITCH VLAN but this would require manual entry of every phone which we have a lot. Not to mention they are leased phones and get upgrades to all phones from time to time.

Any help or suggestions are greatly appreciated,

Thanks.

Only use the CRS3xx series and use this approach.

I am currently using a RB1100AHx4 as the router and a CRS328-24P=4S+RM for the switch. Is it possible with this setup?

Making some headway. I have everything working if I assign my vlan to Ether5 which is the port the switch is plugged into. It is my understanding that I should be able to assign the VLAN directly to the bridge and have it function on any port since the switch is doing the tagging. What am I missing to make the VLAN function over the bridge interface on the router?

This is great for getting started. I managed to get the CRS3 to split the 24 ports into 3 segmented VLANs. From there I added all ports to each vlan bridge and setup a rule to assign a VLAN to by mac address and it worked as well. Thank you for that.

Last question… for the source mac address of the switch rule how do I define the mac so it grabs everything from a certain vendor

Example

Polycom MAC starts with 64:16:7F

I tried entering 64:16:7F:00:00:00/64:16:7F:FF:FF:FF but that doesn’t seems to work. Any suggestions?

I’m assuming from the lack of replies that this is not possible?

Should’ve been 64:16:7F:00:00:00/FF:FF:FF:00:00:00
