If your phones support LLDP-MED you can setup the switch with a Voice VLAN. This wiki covers setting up the Voice VLAN. [URL]   In order to not have to configure the phones you will need to setup LLDP-MED. With LLDP-MED configured the VLAN ID information is passed to the VoIP phone using the LLDP-MED mechanism. By this method, the voice data coming from the VoIP phone is tagged with the exchanged VLAN ID and regular traffic would go to the PVID.   Here is the link to the user guide. LLDP-MED configuration starts on page 540. ftp://ftp.dell.com/Manuals/Common/powerconnect-5524_User%27s%20Guide_en-us.pdf   Once the phone is in the voice VLAN it can still receive an IP address through the DHCP server by using the DHCP relay command. The switch acts as a DHCP Relay agent that listens for DHCP messages, and relays them between DHCP servers and clients, which reside in different VLANs or IP subnets.   DHCP relay and snooping starts on page 563 of the user guide.   Hope this helps.
Hello, I was wondering if there is a way to accomplish the following. I want the switch to tag the traffic on it's own based on the OUI-Table and pass it up to the Sonicwall (DHCP Server/Router) without having the phone itself do the tagging. Is this possible? Currently the setup works if I manually set the VLAN ID on the phone itself, but these phones can work anywhere there is an internet connection meaning if I have to manually add the VLAN tag the phone will not work outside the corporate network.  Thanks
