how do phones automatically associate with a different vlan

[holguie81]

Hi we are setting up a BE-3000 in test lab and and are going to place the it on different VLAN than the data network. We got this point we realized we do not know how to make the phones automatically associate with respective VLAN using DHCP. This is done automatically on the UC500 and never thought about how it was done...

Can some one please shed some light on this?

This is accomplished by creating a type of trunk link between the switch  and phone, allowing the link to pass traffic for both voice and data. Then you create vlan interfaces on the switch that correspond to the subinterfaces.

Configure the port that connects IP phone to switch as follows:

# switchport mode access

# switchport access vlan vlan-id

# switchport voice vlan vlan-id

IP  phone should obtain IP from dhcp pool of the voice subnet and register  with BE3K. The PC should obtain IP from DHCP on data subnet.

Thanks
