Voice VLAN question

[Brett Williston]

We have a department that decided to replace our Cisco phones with Yealink phones. They are configured for data access on VLAN 100. Our Cisco Voice VLAN is 21.  They want their phones to pick up an ip address from VLAN 100. Can a I set the VOICE and ACCESS VLAN both to be 100? Thank you for any advice. This has been an odd project that has been thrust on me after they made the purchase.

You can configure both voice and access vlan 100.

Respected port need to have only one VLAN that is data VLAN 100,  (no voice VLAN required here on that port)

[Brett Williston]

What commands would I issue to turn off the voice vlan for this port ? Thank you.

[balaji.bandi]

we are only suggesting here - based on the information. make sure you understand the setup correctly

if you like Phone and Data for this switch to be part of VLAN 100  - is this what your intent to do ?

config t

!

interface gi 0/0

swithport mode access

switchport access vlan 100

no shutdown

!

[Brett Williston]

Not for the entire switch. Just this port. Is that possible? Thank you.

[balaji.bandi]

if that is your intention to on that port - change gi 0/0 with your correct port on that switch.

so device get Data VLAN IP address from DHCP .

Thank you everyone. I wanted to share the solution I discovered. I set the access and voice vlan both to 100. The yealink phones still were not picking up an IP address. So I turned off LLDP and CDP on the Yealink phones and they were able to successfully pick up an IP address from VLAN 100.
