Private VLANs on the GC728X and GC752X Switches
Hello Netgear Gurus, I am trying to understand how the Private VLANs on the GC728X and GC752X switches operate. I have a Terminal Server that only negotiates to 100 Mbps Full. So we constantly ...

I would prefer to go to the Security > Traffic Control > Private VLAN > Private Vlan Port Mode Configuration config. Because this is what the documentation does request. At that point again, I would expect a different config pushed in place than a classic dot1q
This compares well to similar configurations on different switch models to support the asymmetrical VLAN configurations. And this is again a feature not supported on general dot1q configs. And this is in my understanding not a generic dot1q config - so thus I was talking about that before
Afraid again, have no test horse available. The related answers could come from Netgear switch engineering (via support), some insight could come from comparing the configs generated by the two variants.

Okay you gave me two options.
Option 1
Classic 802.1q way
Option 2
Using the Security > Traffic Control > Private VLAN > Private Vlan Port Mode Configuration
Since I did not use the Security > Traffic Control method, I must have done it the Classic 802.1q way. However the Classic 802.1q way for me is:
config t
int fa0/1
switchport access vlan 51
But in this case that is neither here nor there.
So my answer is Classic 802.1q way. Hmmm wait, Regis, can I get a Lifeline?
Thanks

Okay I accept that answer. I will have to play around with the Security > Traffic Control > Private VLAN > Private Vlan Port Mode Configuration config. I have enough extra switches that I have a development lab to play around with different configurations. I will give it a try and see how it works out.
One question. Private VLANs are used for containing traffic within the community, from my understanding. When traffic needs to go outside of the community, say to another Private VLAN it would need to exit the Community via the promiscuous port. Then where does it go? Would it be routed by a router or Layer 3 switch to the other Private VLAN?
Thanks,
Robert
