Hi,

We currently have a few stacks of 7048Ps as our office switches. We have both IP phones and computers, they each have their own individual ports on the switch (so no phone to PC daisy chaining).

Currently we have all the access ports on the same settings:

1. native vlan is data vlan
2. LLDP-MED assigns voice vlan

When a phone is plugged into the switch LLDP-MED assigns it to the voice vlan and when a PC is plugged in it stays on the data vlan.

We're needing to put in 802.1X in the near future and unfortunately our phones don't support 802.1X so I was wondering how these two (802.1X and LLDP-MED) play together and if there's any interoperability.

I realise I could add all the MAC addresses of the phone into AD and use them as MAB access but that's not a particularly appealing option to me. I was wondering if it's possible to still have LLDP-MED assign the voice vlan and allow traffic for a device that doesn't respond to 802.1X requests? How would I do this?
