Cisco switching question: Can I connect a single windows endpoint which can communicate on one of two VLANs via access port?

Hi everyone,

​

I'm interested in taking a Windows endpoint which doesn't support 802.1q and connecting it to a Cisco switch. This endpoint can be configured for either vlan A or vlan B, but doesn't need to communicate on both at the same time. Both vlans are in separate subnets.

​

Because the endpoint doesn't support 802.1q, I was wondering if it's possible for the access port to be configured for two access vlans simultaneously. One option I am considering is configuring the port with both a data and untagged voice vlan, although I'm unsure if that is a suitable solution. A solution doesn't need to use voice vlan, it's just a thought. Obviously the simplest solution is best.

​

If a voice vlan sounds like the best possible solution, how would the switch differentiate if the traffic is within vlan A or vlan B? From what I can tell from Cisco documentation, this is done via 802.1p for vlan B (voice vlan).

​

Any ideas? Thanks in advance!
