VLAN

[Lewis_Cipher]

Need to extend a vlan to another switch via fiber.  What do I need to do in order to make the connection?

[Mohamad Qayoom]

If the existing switch is VTP server, configure the new switch to be a VTP client.

Configure the VTP domain on the new switch. If you are using a VTP password, configure that on the new switch.

Configure the uplink for trunk if needed.

Hi Lewis,

In order to extend a VLAN to another switch, you will need to configure VLAN Trunking on both sides for the link between the switches.

I would recommend you to go through the following documentations which will give you detailed explanation and examples to achieve this.
