3 important questions on Network security - Implement and troubleshoot switch security features - Private VLAN
What are the two types of secondary vlan's?
-Isolated VLANs—Ports within an isolated VLAN cannot communicate with each other at the Layer 2 level.
-Community VLANs—Ports within a community VLAN can communicate with each other but cannot communicate with ports in other communities at the Layer 2 level.
What is an isolated private port?
An isolated port is a host port that belongs to an isolated secondary VLAN. It has complete Layer 2 separation from other ports within the same private VLAN, except for the promiscuous ports.
Private VLANs block all traffic to isolated ports except traffic from promiscuous ports. Traffic received from an isolated port is forwarded only to promiscuous ports
What is a community port?
A community port is a host port that belongs to a community secondary VLAN. Community ports communicate with other ports in the same community
VLAN and with promiscuous ports. These interfaces are isolated at Layer 2 from all other interfaces in other communities and from isolated ports within their private VLAN.
