Good work!! Thx, Jim. This type of VLAN is used to forward frames downstream from Pports to all other port types and ports. They are used to transport frames from router to hosts to and First comes the Primary VLAN simply the original VLAN VLAN in our example. This needs to be clarified, even if in secondard document. When we split VLAN using PVLANs, hosts in different PVLANs still belong to the same IP subnet, yet provide good level of isolation between them.

This type of VLAN is used to forward frames downstream from Pports to all other port types and ports. This needs to be clarified, even if in secondard document. What Private VLANs PVANs do, is split the domain into multiple isolated broadcast subdomains. As we know, Ethernet VLANs are not allowed to communicate directly, they need L3 device to forward packets between broadcast domains. First comes the Primary VLAN simply the original VLAN VLAN in our example.

Good work!! Thx, Jim. If the certification exams test the very edge of our knowledge it would be good to know specifically how the switch does not simply do the lookup and forward the frame. First comes the Primary VLAN simply the original VLAN VLAN in our example. However, there is difference here. As we know, Ethernet VLANs are not allowed to communicate directly, they need L3 device to forward packets between broadcast domains. In turn, router either permit or forbid communications between subVLANs using accesslists. Why would anyone need Private VLANs?

This type of VLAN is used to forward frames downstream from Pports to all other port types and ports. Next comes Secondary VLANs, which correspond to Isolated and Community port groups. However, there is difference here. This needs to be clarified, even if in secondard document. What Private VLANs PVANs do, is split the domain into multiple isolated broadcast subdomains. When we split VLAN using PVLANs, hosts in different PVLANs still belong to the same IP subnet, yet provide good level of isolation between them.

Regular VLANs usually correspond to single IP subnet. As we know, Ethernet VLANs are not allowed to communicate directly, they need L3 device to forward packets between broadcast domains.
