  • What is a non-routable VLAN? Why would you use one?

    I've heard the term "non-routable VLAN" but am not sure what exactly it means, why it exists or when it's used. It would seem perhaps just by definition that it's an existing virtual local area network (VLAN) that just doesn't have a VLAN interface created for it anywhere on purpose. Do you use it...

  • Associate Vlan with subnet

    Hi, I can't figure out how to associate a VLAN with a Subnet. For subnets you need to have a router in between. For VLAN's trunking...but how do I associate these 2 so when a port on the switch is change from VLAN 1 to VLAN 2 to get IP address from a different subnet DHCP. Thank you!
