VLAN Configuration in config-vlan Mode To access config-vlan mode, enter the vlan global configuration command with a VLAN ID. Enter a new VLAN ID to create a VLAN, or enter an existing VLAN ID to modify that VLAN. You can use the default VLAN configuration (Table 12-2) or enter multiple commands to configure the VLAN.

How do I create a DHCP pool?

Why do we use Superscopes in DHCP?

How do I connect two different VLANs?

The simplest way to enable routing between the two VLANs to simply connect an additional port from each VLAN into a Router. The Router doesn’t know that it has two connections to the same switch — nor does it need to. The Router operates like normal when routing packets between two networks.

Can you have multiple VLANs on one port?
