Telepresence and Voice VLAN assignment

We are using Cisco ISE and 802.1x for authentication. We have an authorization profile that assigns device-traffic-class=voice to IP phones and puts the units on the VOICE vlan.

I am trying to move the Telepresence units (in this case SX20) to this VOICE vlan by assigning it to the same profiles. As far as i can see this works fine.

The unit does not recieve an ip address, nor will it get its ACL applied.

I´ve set up a test VLAN on this switch and if i change the configuration to apply a certain vlan instead it works correctly, and as i said ip phones on works correctly.

Have anyone experienced anything similar with telepresence equipment and 802.1x

When using 802.1x, are you able to see MAC Address of the telepresence in arp table of the switch?

Hi!

Yes it does. Not at site right now but show mac address-table int gig1/0/33 shows correct mac address in the VOICE vlan.
