Hi again,

Unfortunately in this case the map is not completely in accordance with
the terrain. There is no PVE Mapping tab at the Switch config page for
my SRW2016. However the Interface settings (page 26-27 in the manual)
contains a PVE dropdown box listing: <none>, g1-g16 and LAG1-LAG8.

First I selected g16 in this PVE box (I hoped that this would be the
uplink port). However I received an error complaining that I could not
do this because the selected port I was editing (g1) also was a member
of the default VLAN ID 1.

I tried to create a second VLAN with ID 10 and assigned ports g1..g10 to
this VLAN. Then I was able to set g16 as PVE port for g1. However I
have no idea if this is the way it is supposed to be done. I haven't
found a way to assign <none> as VLAN ID for the ports g1 .. g10 so I
just have the PVE stuff enabled and no other 'normal' VLAN ID.

There is no indication in the manual (as far as I can see) that the PVE
mapping stuff only is available for the 48 port model. My SRW2016
switch has the latest firmware version according to the official Linksys
site.

Any suggestions or comments...?

regards

Since the thread ran out of juice, I have another question:

Does it exist other 16port gigabit switchec with the PVE (private VLAN
edge) feature in the same price segment as the SRW2016?

Thanks for hints on this

regards

Hi,

I take the chance of restarting this thread as I have still no working
solution. I tried with the PVE feature of the SRW2016 and I was able to
connect to the internet, but very intermittently. It seemed that the
workstation had trouble selecting which uplink port to select to get to
the internet and which one to use for getting to the domain controller.

But let me rephrase the question a bit:

Does it exist (a) more 'general' solution(s) for our problem..?

We have several classrooms which need continous access to the domain
controller subnet and in addition, internet access only when needed.

How can we avoid connecting ALL classrooms to the internet once the
gateway cable is connected to the domain controller net in one classroom?

The router / firewall IP is on the same subnet as the domain controller.
A small sketch of a similar system is available here (with separate
switches for internet and domain controller):

Connecting / disconnecting the internet is classrooms would be by
connect/disconnect the blue connection in the above sketch.

Thanks if someone have some bright ideas ;-)

Looking at the picture, I think your only option is to use a router.
You will need the router to the east of the switches.

I.e. one router in the domain controller cable for each classroom.
Gigabit router... sigh.

Though I have *no* other options...?
