It will work for other ISP where internet does not come with vlan, with some modifications:

1) the db switch sw2, port 2 egress (outgoing back to the ONT), has to be untagged. port 2 on sw1 is not used but should be untagged as well.
2) vlan 20 is not used if you don't have iptv so don't need to configure it
3) port 8 on both switches can join vlan 100 if you don't have iptv
So I still have to use smart switches and do configuring? I was thinking to just use dumb switches to link the ont to the router and ap in the living room.

Tks for the help.

Yes, smart switches are still needed because the trunk (port 1 of both switches) carries the 2 vlans for wan and lan.

I have a pair of microtik rb260gs (brand new)available for experiment.. the configuration should be more flexible than TPLINK easy manage switch. Any taker?

Tks very much for the advice. Will bookmark it.

And Tks as well to ts for sharing this. It really saves me a lot of headache in planning for my future bto networking.

Cheers

You need to buy the Switch back ,at least a pair to start exploring and also read the Switch Manual carefully, it is using concise English to describe rather than putting down illustrations to explain the case. It is more of testing of your understanding on the language than describing things in Engineering way.


A few points to take note
1) Each brand of Managed Switch used slightly different deployment topology on Trunking.
-Cisco is using a clearer way to manage the Trunk for multiple Vlan
-TP-Link, Multiple way depends on Managed Switch classes.
  • -For Easy Managed SG105/8E , it takes away most settings to make it EASY but more confusing.
  • -The Switches described in the Starhub threads are a better class of TPLink switch which give clear control on Multiple Vlan trunking

With reference to your drawing
Use case Assumptions
1.On Starhub Fibre with Multiple IPTV at remote locations
2. Use Single Cable Trunk to carry IPTV & After Router's LAN to multiple locations.
3. TP-link SG105/8E Easy Managed switches are used.
4. Just my assumptions, Not familiar with Starhub actual Vlan ID.
-IPTV Vlan ID:1091, Signal from ONT Port-2
-Internet -> No Vlan ID, Signal from ONT Port-1

My Proposal
1. Your Vlan Topology should be simplified to 2 types
  • -IPTV , use the exact Vlan ID:1091
  • - After Internet Gateway(Router) Internal network signal distribution for Access Point( AP) and Ethernet ports usage
    Use Vlan ID:100, avoid using Vlan ID:10 (this is known signal for Singtel Internet)

    The 3rd Vlan20 is redundant for your application with Wan directly connected to the ONT.


On DB SW1
-2 Trunking by Port 1 & 8 to carry all signals (IPTV and after gateway
Vlan 1091 : Tagged Port 1,2 & 8
Vlan 100: Tagged Port: 1,8, & Untagged: 3-7

Port PVID settings-Very Important , you must set correctly
Port 1,8 PVID=1
Port 2, PVID=1091
Port 3-7, PVID=100

On Living Room SW2 & SW3

Vlan Settings
Vlan ID :1091, Tagged Port 1, tagged: *Port 2

*Port 2: Tagged or Untagged ? is really dependent on IPTV Settings, if the IPTV Server is expecting tagged Frame on return , then Port 2 output should be tagged. Just experiment on this to find out.

*Singtel IPTV itself, Untagged Port settings is used, signal going back to server is without tagged frame.

Vlan ID:100, Tagged Port-1, Untag Port 3-5

Port PVID Settings
Port 1: PVID=1
Port 2: PVID=1091
Port 3-5, PVID=100

You need to set the 802.1P QoS Priority Settings, try using the auto configuration with 802.1P QoS setting

Notes on TP-Link switch FW bugs
1. Try applying Save configurations after completing the full setup.
-There are bugs in the FW that only save configurations once.
2. Clicking applying change of settings is only effective for current power cycle, you need to use the external Save Configurations to really write to Flash memory.
3. It is always good to use backup configuration to File to backup known good working configuration. Anything wrong you can restore to good working point.

4. Validate Switch retaining last settings after power cycling . I found the switch sometimes does not save your last applied settings..
-Wasting many hours to figure out this stupid bugs

I managed to find a network splitter , you will need a pair to work.

No need to use the managed switch or configure.

So far using it for a month, no issue.

If you are talking about the type of splitter that splits a 8-wire cable into two 4-wire cable, yes, it will work and costs only a few dollars for a pair.

However, the speed is only 100Mbps. But I think 100Mbps is more than enough for most people.

So if you are using splitter and your broadband plan is 1Gbps, you should change it to lower speed and save some money.

Reading posts here..mostly stuck with Single Lan point to living hall with no return line to loop back to DB for further distribution.


There is one solution that you dont need to lay extra cable yet able to loop back for further distribution without much suffer on bandwidth ( up to 1 GB Full duplex).


By using 2 managed switch, you can achieve this goal .

1. ONT -> Managed Switch 1(MS1) => Network truck with single LAN cable to link to Managed Switch 2 => Living Hall Router & its LAN Port loop back to MS2 switch to be routed back to MS1 LAN Port for other rooms distributions.



MS1 Setup
- 1 Trunk Port ( ONT -> MS1-Trunk Port -> MS2 -Trunk Port-> Router WAN Port
- VLan grouping based on ISP vlan settings

-Define Vlan Group for Other rooms distribution, Vlan-InterLAN


MS2-Setup
-Dedicted TrunkPort to route traffic from MS1 and To MS1
-Vlan group for Router WAN Port & Trunk
-Vlan group ports for Router's LANPORT to MS1 Lan Ports- Vlan -InterLAN


Since the only physical LAN has full duplex bandwidth of 1GBps Up and 1 GBps Down.

Since the internet application mostly download more than upload. With assumption of 9:1 Ratio of Download /Upload (Mainly for signal acknowledgement) .

You will have 900Mbps for download bandwidth and 100 Mbps for uplink acknowledgement.

Single Trunk have 2 lanes of Download link(DL) and 2 lanes of UpLink (UL)


Download Link Signal
1.Internet ->ONT ->Trunk MS1 (Trunk of 2 lanes download) -> MS2 ( 2 Lanes of receiving ) to Router WAN

2. LAN Ports from MS1 Network will use the same DL lanes to transfer signal back to Router's Lan Port.
*This uplink signal ration should be around 10% of Internet incoming traffic


Uplink Path
1) Wan Out from Router to ONT to Internet
10% of Downlink traffic
2) Network traffic From Router's LAN Port ( MS2 ) to MS1-LAN download traffics
Since this is internet download, you still have 90% bandwidth or 900 Mbps.

I have ordered 2 managed Switch from Amazon with trunk capability to experiment this concept. I should be able to share more after getting the switches from Amazon. $120 project...

This concept is not new, it is documented by many network switch makers.
One of the more easy to understand concept is found at Mikrotek wiki page.

Just get a tplinl tl-sg105e or tl-sg108e. Its only sgd$35 from cybermind sls (pc show).. Contrary to what others say, this switch can set vlan priority4 for iptv if u look at the settings properly. I can pm config, it works v well

Since IPTV STB is only 100Base-T, does it slow your other services on other vlan down to 100 or will you be able to run gigabit for the internet?

no, the rest can still run gigabit.

The IPTV STB only comsume about 6-10Mbps, so it has very little impact to the switch which is capable of Gbps.

Thanks!

Does most managed switch able to do QoS on the particular trunk?
I'm afraid if I do some heavy file transfer between my PC and my Server would saturate the gigabit connection thus leaving my TV skipping.
