Question

How can I configure 3 vlan's on a cisco switch with domain names?please can someone help me?

Answer 1

By domain names I think you mean to add three VLAN's and create a VTP Domain for them. A switch can only belong to a single VTP domain. This depends a bit on if your running CatOS or IOS, but I will make an assumption of IOS for now. First I would create the VTP Domain:

vtp domain <enter name here>

vtp mode <transparent | server | client>

If you don't know much about VTP please check docs on CCO as it can be a tricky technology - most commonly these days is to use transparent as it is safest, but in large L2 domains client/server is still common. Next create your VLAN's:

vlan 2

name <enter descriptive name>

vlan 3

name <enter descriptive name>

vlan 4

name <enter descriptive name>

Unless you only have a single switch, you will need to configure a trunk, but you didn't ask about that. That's all there is to it - create the domain, create the VLAN's and you are set. On VLAN's, I left out VLAN1 on purpose by the way - it should not carry production traffic as a best practice. Hope this helps.

Try what you think is best

Answer 3

Which Cisco switch?  Which router?  Not all Cisco products support VLAN tagging.
