www.dell.com | support.dell.com Community VLAN: A community VLAN is a secondary VLAN of the primary VLAN: • Ports in a community VLAN can talk to each other. Also, all ports in a community VLAN can talk to all promiscuous ports in the primary VLAN and vice-versa. • Devices on a community VLAN can communicate with each other via member ports, while devices in an isolated VLAN cannot. Isolated VLAN: An isolated VLAN is a secondary VLAN of the primary VLAN: • Ports in an isolated VLAN cannot talk to each other. Servers would be mostly connected to isolated VLAN ports. • Isolated ports can talk to promiscuous ports in the primary VLAN, and vice-versa. Port types: • Community port: A community port is, by definition, a port that belongs to a community VLAN and is allowed to communicate with other ports in the same community VLAN and with promiscuous ports. • Isolated port: An isolated port is, by definition, a port that, in Layer 2, can only communicate with promiscuous ports that are in the same PVLAN. • Promiscuous port: A promiscuous port is, by definition, a port that is allowed to communicate with any other port type. • Trunk port: A trunk port, by definition, carries VLAN traffic across switches: • A trunk port in a PVLAN is always tagged. • Primary or secondary VLAN traffic is carried by the trunk port in tagged mode. The tag on the packet helps identify the VLAN to which the packet belongs. • A trunk port can also belong to a regular VLAN (non-private VLAN). ip local-proxy-arp c s Enable/disable Layer 3 communication between secondary VLANs in a private VLAN. Syntax [no] ip local-proxy-arp To disable Layer 3 communication between secondary VLANs in a private VLAN, use the no ip local-proxy-arp command in the INTERFACE VLAN mode for the primary VLAN. To disable Layer 3 communication in a particular secondary VLAN, use the no ip local-proxy-arp command in the INTERFACE VLAN mode for the selected secondary VLAN. Note: Even after ip-local-proxy-arp is disabled (no ip-local-proxy-arp) in a secondary VLAN, Layer 3 communication may happen between some secondary VLAN hosts, until the ARP timeout happens on those secondary VLAN hosts. Defaults Layer 3 communication is disabled between secondary VLANs in a private VLAN. Command Modes INTERFACE VLAN 1156 | Private VLAN (PVLAN)
