Cisco Nexus 9000 supports various Private VLAN (PVLAN) port modes that provide isolation and segregation of network traffic at the port level. The three supported PVLAN port modes on Cisco Nexus 9000 are:
Community Host: In this mode, the PVLAN port belongs to a specific community of hosts within the same PVLAN. The traffic within the same community is allowed to communicate with each other, but the traffic from one community cannot reach another community. Community host port mode is used for servers and other devices that need to communicate within a specific group or VLAN.
Isolated Host: In this mode, the PVLAN port is completely isolated from other ports within the same PVLAN, including other isolated ports and community ports. The only communication that is allowed is with the promiscuous port. This mode is used for security-sensitive devices or for devices that do not need to communicate with other devices within the same PVLAN.
Isolated Host Trunk: This mode is similar to the isolated host mode, but it is used for trunk ports that carry traffic for multiple VLANs. The isolated host trunk mode allows multiple isolated hosts to be connected to the same trunk port. The trunk port is configured with a list of allowed VLANs, and the isolated host traffic is allowed only on the VLANs that are associated with the isolated host.
Other PVLAN port modes that are not supported on Cisco Nexus 9000 include FEX port, port channels, and virtual port channels. FEX port is a mode used for Fabric Extender ports, which are used to extend the network fabric to remote locations. Port channels and virtual port channels are used to bundle multiple physical ports into a logical port channel for increased bandwidth and redundancy.
