Voice and Data VLAN in same port

[SMK91]

Hi All,

When we using both Voice and Data VLAN in the same switch port, Can we keep the Data traffics in VLAN 1 and assign a new VLAN for Voice Traffic..?

interface GigabitEthernet x/y
switchport access vlan 1
switchport mode access
switchport voice vlan 20

Is this possible?  Please help.

Yes its possible.

for your configuration, phones will work in vlan 20 and data in 1

Hi Nithin,

Can we use these same configurations with non-Cisco phones?

yes possible with the config, make sure you have Options set in DHCP for the Voice VLAN.

[SMK91]

Thank you, Balaji. 

What do you mean by Option set in? Is that 150 or 66? Is that necessary one?
