Cisco Video PortalVery nice. Hey Brandon, thanks for the comment! Yeah, I did make some assumptions. I just want to show simplicity of the configuration of QoS on a Voice Vlan. Your additional observations, I believe, are extremely valuable in case others come and view the video and are still having issues. It gives them ideas to solve their own issues. Thanks again.

VLAN Configuration on the 200/300 Series Managed Switches
So I have been at this for about a week now with a lot of trouble along the way. Everything is working so far and we can even register our Cisco IP phones. The problem is, they will only register as an access port assigned to our voice VLAN. If I try to trunk to port to allow both Voice and Data, the phone refuses to register. The only way I have been able to register the phone is by making the port an access port and allowing the Voice VLAN specifically, doing this no data can transfer to the attached computer. If you don't need the smart port function turn it off. That "feature" kicked me in the pants for 2 days. I would set a trunk vlan on a port, plug in a computer and the smart port would reassign the port back to vlan 1. If I reset the port it would stay the way I wanted until I unplugged and plugged in the device back in. Now if you want to use the smart port function, it does have its uses. You just need to set it so that when it sees a phone it sets the right vlans specific for a phone assuming a PC will be behind the phone. You will want the smart port function to tag the voip lan and untag the data lan. Access ports belong to only one VLAN, trunks belong to all by default. If you do not specify a VLAN for an access port, it defaults to 1. Also, access ports do not tag frames either dot1q or isl which is required for trunks to separate traffic. Second, you are thinking of traditional ios that has the voice vlan command and makes what is operationally a trunk port seem like a 'special' access port. Then of course you need your voice server on the same VLAN probably on an access port or if you are hosted you may need inter-vlan routing to let them reach the Internet or wherever. Sorry for the delay, just got back into work. We have a couple of different models of Cisco IP phones, the one I am specifically using to make sure they work with the switch is a CP Brandon, I'll try to turn off the macro smartport and see if that helps at all. We are running the switches in Layer 2 mode and would prefer to keep it that way if at all possible with our setup. Also, thanks! Been lurking around for answers but can't find anything specific so I decided to make an account and ask away haha. Hmm, so I couldn't shut off macro smartport with that command and can't seem to figure out how to disable it. This is odd to me and I'm not sure what to enter here. Also there is still no data getting through to the computer from the phone. Sounds like that phone lost config and is asking to be setup from scratch.

VLAN configuration on Cisco SG300/SG500
Usually, IP phones sit next to a computer on the same desk. They require the same UTP cables as computers and also use Ethernet. If we want to connect them to a switch, we have two options. You probably want to separate the data from the computer and IP phone. This is something we can do with voice VLANs. It will look like this:. Behind the scenes, we have a trunk between our switch and IP phone. The port on the IP phone that connects to the computer is an access port. The IP phone will forward all traffic from the computer to the switch untaggedtraffic from the IP phone itself will be tagged. We configure the interface in access mode and use VLAN for the computer. We can also take a look at the trunk status. Although this will show us that the interface is not-trunking, it does tell us the two VLANs that are used:. Above we see that VLAN and are allowed on this interface. Although it shows up as non-trunking, keep in mind that in reality, this is a trunk. If you have any questions, feel free to leave a comment in our forum. Yes you are correct in your description. Any traffic coming from the PC through the phone will be untagged and will go to the access VLAN configured on the port of the switch. All voice traffic is tagged and will go to the voice vlan configured on the port of the switch. In other words, a Quality of Service technique is automatically incorporated into the functionality of. In the past, before the advent of the switchport voice vlan command you would have to configure a port as a trunk port that included both the voice and data VLANs.
