2. A VLAN can contain more than one port, and one port can belong to more than one VLAN.
5. Instances of Port VLAN
Requirements: The host under the LAN1 port can communicate with the hosts under the LAN2,
LAN3 ports, but those under the LAN2 and LAN3 ports cannot access to each other.
Configuration steps:
1. Modify VLAN 1, whose member ports only include: 1, 2.
2. Create VLAN 2, whose member ports are: 1, 3.
Analysis: Both LAN1 port and LAN2 port belong to VLAN1, both LAN1 and LAN3 belong to
VLAN2; the hosts under the fixed LAN1 port can communicate with the hosts under LAN2,
LAN3 ports. Additionally, both LAN2 port and LAN3 port are not in the same VLAN, and the
hosts under LAN2 and LAN3 cannot access to each other.
