Has anyone worked on this? Got some 3750 LLDP code so we could do dot1x and voice vlans with Avaya 4610 phones. I am able to get the 4610 to authenticate with my Cisco ACs 4.1 server, but I am having trouble giving the phone the voice vlan. I am trying to use the IETF radius attributes to give the phone the voice vlan. From what I understand, the ACS server will authenticate the phone using CHAP username/password, then the ACS server sends the Voice Vlan info to the switch with LLDP-MED values. Once onto the voice vlan, I pass the DHCP values for the Media Server and the TFTP server and thats it. I just cant get the ACS server to send the phone the voice vlan using LLDP-Med. Here is a snippet from the doc on using a Foundrey switch. It appears all I have to do is set ACS to give out the vlan with the key work "Voice" and it should send that info to the phone.
"Click the Configure Attribute? button and configure the Vendor Specific Attribute (VSA). Enter 211 for the Vendor-assigned attribute number. Select String for the Attribute format, and T88 or Tvoice for the Attribute value. VSA 211 is used to support a tagged VLAN. T88 means tagged VLAN ID 88 and Tvoice means tagged VLAN name voice. Once the Microsoft IAS authenticates the phone, the Microsoft IAS will send VSA 211 to the BlackDiamond 8810. The BlackDiamond 8810 will move the phone?s MAC address dynamically into the tagged VLAN (note that VLAN 88 or VLAN voice is not statically configured on ports connected to the phones). The BlackDiamond 8810 will also send this VLAN ID associated with its name ?Voice? (configured on the BlackDiamond 8810) to the phone via LLDP Media advertisement. When the phone identifies the VLAN name as ?Voice? (?Voice? is a key word), the phone will reset and use this tagged VLAN. The BlackDiamond 8810 will forward tagged ?Voice? VLAN packets after the phone is authenticated again. The phone should be able to reach the DHCP and TFTP server and register to Avaya Communication Manager if configured properly."
