Configure an IP address on a VLAN interface.

Figure 24 shows an example of a typical VLAN configuration.

Comparing with port-based VLANs, protocol-based VLANs operate in a different way. 
After you configure protocol-based VLANs for a switch, the switch inserts tags 
automatically in the received untagged packets according to the protocols with which 
the packets are encapsulated. This enables packets of specific protocols to be 
transmitted in corresponding VLANs. For ease of network management and 
maintenance, you can associate services with specific VLANs by configuring 
protocol-based VLANs.

The following section describes protocol-based VLAN configuration tasks:
