Configuration Procedure
1 Create VLAN 2 and enter its view.
[SW5500]vlan 2
2 Add Ethernet1/0/1 and Ethernet1/0/2 to VLAN2.
[SW5500-vlan2]port ethernet1/0/1 to ethernet1/0/2
3 Create VLAN 3 and enter its view.
[SW5500-vlan2]vlan 3
4 Add Ethernet1/0/3 and Ethernet1/0/4 to VLAN3.
[SW5500-vlan3]port ethernet1/0/3 to ethernet1/0/4
Networking Requirements

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.
