Private VLAN Configuration Example
The following example shows a private VLAN topology.
Figure 98. Sample Private VLAN Topology
The following configuration is based on the example diagram for the C300–1:
• Te 0/0 and Te 23 are configured as promiscuous ports, assigned to the primary VLAN, VLAN 4000.
• Te 0/25 is configured as a PVLAN trunk port, also assigned to the primary VLAN 4000.
• Te 0/24 and Te 0/47 are configured as host ports and assigned to the isolated VLAN, VLAN 4003.
• Te 4/0 and Te 23 are configured as host ports and assigned to the community VLAN, VLAN 4001.
• Te 4/24 and Te 4/47 are configured as host ports and assigned to community VLAN 4002.
The result is that:
• The ports in community VLAN 4001 can communicate directly with each other and with promiscuous
ports.
• The ports in community VLAN 4002 can communicate directly with each other and with promiscuous
ports.
• The ports in isolated VLAN 4003 can only communicate with the promiscuous ports in the primary
VLAN 4000.
