Data VLAN and Voice VLAN on same port
Can anyone outline the steps to configuring voice and data vlans on the same port. I need to be able to connect an Avaya phone (9608) and a PC in the same switch port. There is a dhcp server on each vlan. On the data vlan the address include 192.168.1.1-192.168.1.254. On the voice vlan the address include 10.252.1.1- 10.252.1.254.
Any help would be greatly appreciated.

Here is some documentation on setting up Voice VLAN on 2 different models.
55xx - en.community.dell.com/.../configuring-dell-powerconnect-55xx-series-switch-voice-vlan.aspx
62xx - www.dell.com/.../pwcnt_voice_VLAN_support.pdf
Here is a sample config:
****VLAN 10 is configure for voice****
****VLAN 200 is configure for data. ****
****CoS (802.1p) of 4 is use for the the voice****
Console(config)# voice vlan
Console(config)# interface ethernet 1/g10-1/g15
Console(config-if)# switchport mode general
Console(config-if)# switchport general allowed vlan add 10 tagged
Console(config-if)# switchport general allowed vlan add 200 untagged
Console(config-if)# switchport general pvid 200
Console(config-if)# switchport general allowed vlan remove 1
Console(config-if)# voice vlan 10
Console(config-if)# voice vlan dot1p 4
Console(config-if)# voice vlan data priority untrust
Console(config-if)# end
The PVID command is what tags the incoming traffic that has no voice mac address.
Page 615 of the owners manual goes over the Voice VLAN commands.

Page 384 of this manual also takes us step by step on creating a Voice VLAN.

Hope this helps,
Keep us updated if you can.

I changed the 2808 switch from managed mode to unmanaged and the phone obtained an IP address immediately. I will look into adding the IP helper on the 5548P.

Do you have a IP helper command set up on the 5548P directing the DHCP UDP packets to VLAN 501? The 2808 should not be blocking anything. It should simply pass thru the 2808 to the phone systems. It may be an incompatibility issue with the phone itself. Does the phone support LLDP?

Thank you for the instructions. I was able to get it setup and working on my 5548P switches.
However, I still have one set of phones that cannot connect. This set isconnected to PoE injectors, then to a 2808 switch, witch is connected to a 5548P switch. I have set up Voice VLAN 501 on the 2808, the phones identify the VLAN correctly then hang on "Waiting for LLDP". Is it a limitation of the 2808 switch that is blocking DHCP from reaching the phone on VLAN 501?

IP addresses are unique algorithms that allow data exchange over the Internet between your device and the rest of the world. Each device that is connected online has one. Just like our unique email address and phone number that people use to communicate with other people around the world. router-help.com
