Vocie VLan

[Network Pro]

Hi,

i am starter to VOIP.

we have a core swich and few access switches connected to it. THe phones are daisy chained with the PC's on the access switch

pc ------> phone -----------> switch

pc is a different subnet and phone is a different subnet

so the config on access switch:

int fas0/21

switchport mode access

switchport access vlan 20

switchport voice vlan 30

is the above correct ?

also the on the core switch, how do i create a voice vlan (access switch and core switch are trunked)

is it just ?

vlan 30

name voice

Thanks

so if i do

vlan 30

name voice

this is just normal vlan isnt it? its not voice vlan...

so how will the access switches understnad if

switchport mode access voce vl103

as the above vlan on the core swtich is just a normal vlan

Hi,

On the access port we enter switch port voice vlan XXX, so that switch can give voice vlan info with the help OF CDP.

But vlan is a vlan to seprate the diffrent Kind of traffic.
