Have a couple of the TL-SG108PE (PoE version) on the bench at the moment. 
Do you have a link to a good doc/book/pdf about vlan configuration and that sort of tech?

msssltd, not a straw man argument at all. He commented that smoking is a choice. How am i supposed to take that statement other than to say smoking deaths are more OK than shooting deaths?

If he is saying that, It's his argument to make, but for me, a life is a life.


A small change in the amount of smokers would result in a large amount of lives being saved
A large change in the amount of mass shooters would result in a small amount of lives being saved.


How is that "an intentionally misrepresented proposition that is set up because it is easier to defeat than an opponent's real argument."


A creaking creeping shadow
stiff against the freezing fog
glares at a tickless watch.

Time has failed him -- all things shall pass.

Moderator request:  Lets keep to the subject about latest purchases here.
Not about gun laws that are not Arduino related.

Do you have a link to a good doc/book/pdf about vlan configuration and that sort of tech?
1. Requirement - Why do I need a VLAN?
2. Specification - What sort of VLAN fits the requirement?
3. Procurement - What device provides the VLAN functionality which matches the specification?
4. Implementation - How do I configure a VLAN and that sort of tech, on the device I have procured?

Answers to Q1, as good as any, can be found in post 2, here  https://community.spiceworks.com/topic/85928-why-use-a-vlan

Basic knowledge of OSI (7 layer concept) is assumed.

Typically, a single 8 port switch provides no good reason and several reasons not, to implement a VLAN.

Thanks for the answer/link.

I need for a separate network for testing without other network traffic. I can create a standalone network, and the switch will do the job too. As needs grow/differ in near future I also want to learn about QOS and VLAN etc Therefor I bought the managed version of the switch to get some hands on experience.

Hi,
Before Christmas I was given a nice constructors pen by one of our suppliers who we have bought heavily off in 2017.
I believed it was this pen, available locally for about $15.00AUS.

It ran out of ink today, so I went looking for the ink cartridge, which is not a standard size.
My pen has TROIKA written on it, I noticed that the above pen actually had some subtle differences, and is actually a cheap copy.
This is a TROIKA. "Mine ! ! !  :) :) :) :)"

On ebay they sell for $50 to $70... :o :o :o :o
The Australian TROIKA shop sells them for $35.. hmmm might be some money to make... :) :) :)
Refils 5 for $12.
So, I will treat it with a bit of care from now on...

Tom.. :)
Everything runs on smoke, let the smoke out, it stops running....

That would be a port based VLAN. 

Port based VLANs partition the switch into mulitple 'virtual' switches.  Sometimes called a vertical partition - Imagine several switches in a stack with a line drawn vertically down the stack.  However, no one port can appear in more than one port group.  For a port group to reach the internet, you would need to assign one port  to the router uplink. 

An 8 port switch, partitioned into 2 port groups, with each group able to reach the internet, ends up having only 6 ports usable by devices - And you start to realise the limitation of a single 8 port managed switch.

I also want to learn about QOS and VLAN etc
QoS is a subject in it's own right but once again, brings little utility to a small network.  QoS (only) works on egress, when traffic leaves a port.  With a Gb of bandwidth, and the major bottleneck (typically) imposed by an asymmetric link to an ISP who is unlikely to respect your tags, once again the limits of having only 8 ports starts to bite.  You might find a reason (VOIP, CCTV) to use port based or DSCP QoS, at a push.

Shame they don't do SNMP as that is useful, even in a small network.

For training purposes, I recommend grabbing hold of a Ubiquiti ERX5.  For a little over 50 bucks you get a whole bunch of L2-L7 functionality in one box.  Not as fast as a Microtik but far more flexible.  It's a steal at the price.

.....
Did a few hours of youtube and reading about VLAN's and the SG108 also can assign one port as MTU port which is part of every VLAN of the switch so 1 only need one line to the router. That gives me 7 ports to divide over the different VLAN groups (e.g. one group of 2 and one group of 5 devices)

Thanks,

MTU is TP-Link's one-click version of a multi-tenancy configuration.  The switch is partitioned into 7 separate VLANs, all sharing the uplink (MTU) port.  When Port 1 is assigned to the MTU.  Port 1 can communicate with all ports.  Ports 2-8 can only communicate with Port 1.  The common use case is where each port is a downlink to an unmanaged switch.

It looks like you might be able to do what you want using 802.1Q.

Layer 3 could get  interesting though

Costco "Hackintosh" (Dell 8930), plus a 512G M2 PCIe SSD to go in it.  Finally getting around to replacing my 2008 Mac Pro (and I've given up the idea that Apple might give me what I want.  Sigh.)  (Got the 4k monitor for it a while ago.  No being able to connect that to the old Mac was the last nail in the coffin.)

The installation of MacOS High Sierra took a bit of fiddling, but it seems to be working well.   Transferring data is being "annoying" - copying data over the net is slow (I'm not sure why.)  And "Photos" just took several hours to process my old iPhoto library.

I have all my stuff on a USB drive only so transferring to another PC is just plug out and plug in.

Two or three hours spent thinking and reading documentation solves most programming problems.

I used to use one of those for inserting what i think were called bailles.

Basically tee shaped pins for through hole connections on double sided PCB's.

It would be easier if I just wanted to transfer everything.   I'm trying to take this opportunity to get rid of some of the cruft (like the PPC executables, the multiple copies of 20GB videos, the oldMac/oldMac/system and Downloads/oldDownloads/oldDownloads,  and the "kids laptop backup 2010"...   The old system has something like 4.3TB of disks, plus a 4TB time machine backup (4 drives total), and I want to consolidate.)
