Ip Local-Proxy-Arp - Dell S4810 Reference Manual

Port Types:
• Community port: A community port is 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 a port that, in Layer 2, can only communicate with promiscuous ports
that are in the same PVLAN.
• Promiscuous port: A promiscuous port is a port that is allowed to communicate with any other port
type.
• Trunk port: A trunk port carries VLAN traffic across switches:
– A trunk port in a PVLAN is always tagged.
– A trunk port in Tagged mode carries primary or secondary VLAN traffic. 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).
