VPE on SRW2024

I need to test PVE using my existing SRW2024 to justify purchasing an SG300 version for a new application.

My main uplink is via "g1".

My current settings have all ports in the default (and only) VLAN.

On the Port Settings screen for "g2",  I set PVE to "g1".

On the Port Settings screen for "g3", I set PVE to "g2".

All other ports have no PVE setting.

Results:

All other ports can talk to next hop connected to "g1".

Neither "g2" nor "g3" can talk to anybody, including the next hop connected to "g1".

They can't even talk to the switch.

Firmware version 1.2.2b

What I want to happen:

PCs on "g2" can not see PCs on "g3" (and the reverse), but they must talk out "g1" to get to the internet.

The doc just does not seem to indicate anything on using this feature.

Does PVE just not work on these boxes?

Hi David, PVE should not be set on the uplink port. Only the ports you want "isolated"

The PVE setting for port "g1" *is* blank. The only two ports with any value in the PVE setting are "g2" and "g3". Both of these have a PVE value selected as "g1" on the port management setting screen..

Hi David, I think I see the problem. It looks like your PVE groups are different.

On the Port Settings screen for "g2",  I set PVE to "g1".

On the Port Settings screen for "g3", I set PVE to "g2".

How the PVE works is it maps a source port to a destination port to over write the forwarding table. The uplink port "protects" the source port.

You need to set the PVE for g3 to g1 if g1 is your common uplink port.

Sorry,

Actually, the statement:

On the Port Settings screen for "g3" , I set PVE to "g2".

Is a TYPO.

It should say:

On the Port Settings screen for "g3" , I set PVE to "g1".

Both ports point to "g1".

I will try to get a picture and attach.

David, that configuration looks correct.

I don't have much more memory for this switch but the best memory I recall it used to work.

Then again, this model switch is considered pretty old. I don't have much more to add to the post unfortunately.

I can assure the 300 and 500 series is nothing like this device and works a lot differently and in most ways better.
