Is it possible do the following??

Hi All,

 

I hope you guys are ok and before I start, just thanks to everyone.

 

I am starting to prepare my Cisco training however I just find myself into a problem at work.

 

I have PC and phone (VoIP) connected throught the same cable, meaning that the phone, which is PoE, makes the Switch funtion, therefore just 1 cable reaches the Cisco Switch, model SG500X-48 48-Port Gigabit with 4-Port 10-Gigabit Stackable Managed Switch.

 

I wonder to know whether is possible or no make the following. I would like to create 2 VLAN to make the diffence between data and voice. Would it be possible without splitting the cable in 2 reaching the Switch with 2 different lines? In other words, Is it possible to create different VLANs to separate Voice and Data that run over the same cable?

 

To be honest guys, I imagine that this is not possible but who knows.

 

Thanks to everyfone for the answers in advance.

Ruben,

 

It sounds like you just need to configure a voice VLAN on the switchport the phone is connected to. Configuring the voice VLAN essentially turns the switchport into a dot1q trunk, but one that only allows two VLANs. The workstation attached to the phone gets put into the switchport VLAN, while the phone gets put into the voice VLAN. A Cisco phone will automatically learn the VLAN IDs via CDP. I'm not sure if the syntax is the same for the SG500 as it is for IOS, but normally configuring a voice VLAN would look something like this:

interface gi0/1
 switchport voice vlan 10

If you are using the GUI, it might be configurable by selecting VLAN Management > Voice VLAN from the left navigation pane.
