SG350-28P Voice and Data VLAN config on a Single Port

[ranjit123]

Dear All,

We have a SG350-28P PoE switch and we are looking to configure Voice and Data on a single port.

I have the catalyst switch configuration and its working i am looking for the SG series configuration and have watched some vidoes on youtube. It seems that i need to tag the Voice VLAN, so i am looking for a working voice vlan and data vlan configuration for the same. Request you all to share with me the working CLI configuraiton example for the same..

Regards

the standard config should work. (make sure you understand the syntax, if you doing live environment the port will go down and up).

(config)#voice vlan id 100

(config)#voice vlan state auto-enabled

(config)#interface fa1   <--change the interface or range depends on the requirement

(config-if-range)#switchport trunk native vlan 101

(config-if-range)#switchport trunk allowed vlan add 100

Hello Balaji,

Just to make sure here data vlan is 101 and voice vlan is 100..

can you confirm the same..

change the config as per the requirement, voice and data

create a voice vlan 100 flip the confg.

Hello,

Can you please update me the sample config template..

Is this correct

Inteface <>
switchport mode access
switchport mode access <data vlan?
switchport voice vlan <voice vlan>
spanning-tree portfast

Hi guys,
This is the solutions you need to know about how to configure Voice and Data VLAN by using the same network cable on Cisco SG-300 Series manage switchs.
I'm using Cisco SG-350-28P and I have configure interface g17 to handle traffice for Vlan12(Vocie) (I'm using Zycoo Deskphone)and VLAN16(Data), both of them used shared network cable together.

[balaji.bandi]

is this solution or posting as problem ?

[chantha]

this is a solutions brother. It's working with my environment

[chantha]

And please make sure we have enable LLDP services on interface that connected to IP phone like (Zycoo) to let switch and IPphone could understand each others.

Switch(config)#interface GigabitEthernet17

Switch(config-if)#lldp receive
Switch(config-if)#lldp transmit
