working Singtel Vlan Settings with TPLink SG108E

Creating a new post to share with folks here.

Setup to get t Singtel Internet and IPTV working with 3rd Party Router (Without Vlan Support) with TP-Link SG108E Easy smart switch in Between ONT and Router .

Previous many have reported issues to work with the TPLink Easy Smart Switch.

Before this ,I have read many post here and many reported TP-link managed switch is not compatible with 802.1p priority setting and therefore cant get IPTV to work and Internet is also intermittent.

Below is setup I have done and initially also cant get it working with reference from many posts here but luck come in.

I did a reset to managed Switch and do a fresh setup and magically my notebook started to receive DHCP with IP address allocation on my ONT-> Switch-> Notebook LAN . Internet is working fine

Some tricks here
-Not setting it up to use 802.1p priority based using port base with modified Priority setting below ( The settings reference is based on UserGuide of TP-SG108E , which has a weird matching, 802.1p Priority 0 is not mapped to the lowest setting of Port-base Queue settings
After getting direct connection from ONT to Switch to untagged internet connection to work.. Switching it back to 802.1p does not impact the settings any more.

Hardware Smart Switch :TP-link, TL-SG108E , version 3 Hardware,

'->' Denotes LAN Connection
Network Flow

Switch Ports
Port 1- ONT
Port 2- Tagged Port to serve as backup, to allow use of Singtel router/routers with Singtel Vlan settings
Port 3- To Routers without Vlan settings
Port 4-7 - Setup as Lan group ports , treat it as unmanaged switch , for use to route to other rooms AP/Switch/Bridge

Port-8 - Singtel IPTV

Vlan Table

*Grouping of IPTV, can only select 2 ports, ONT and A single port, putting more than 2 ports slow down packet forwarding and resulted in stutter frames.

PVID Settings,
*actual setting, port 2 should have PVID 10

Prior to get 802.1P CoS to work, manual Port Base Priority was used.

Final 802.1p Settings

IGMP Snooping

Something to monitor with bad received packages

Next Step is to monitor Internet performance.
I am currently setup the network running at my home with Google On Hub x2 with MESH Setup.

Singtel 1G Fibre with MIO TV Package.

1.Singtel IPTV- Working
*The Vlan group for IPTV 20, can only have 2 ports ( 1,8 ONT +SIngle IPTV Output), grouping more than 2 will have pause video issue.

2. Internet - Working
-Video Streaming working fine
-Phone applications no abnormally

Internet Performance needs further validation

Internet connection with Wifi Mesh - 600 MBps up/download based on Google App transfer speed reporting

Internet Speed LAN-with Speedtest.net, misleading results

Speedtest.net ->
Download - 920 MBps ,
Upload ->500 Mbps with Singtel Server

-> Revert to ASUS AC 56S to ONT, got the same result range, Assuming server Busy or my LAN connection is having some problem. In the past , I would get 900/900 MBps range of LAN Connection.

SpeedTest.net Beta :> Downlaod speed < 200 MBps, Upload- 550 MBps with Singtel Server, other servers , no download speed.

Thanks for the hard work.

Any update or information on the 4655 received bad packets?

I did some further probing and change of network settings but doesnt seem to improve the case.

There is always 10% bad package received at ONT point and no bad packets after Router.
My Fibre Point 2-3 weeks back got a disconnection issue that NetLinkTrust needs to do a physical patching, that could be the issue. The Noise level is still high.

Internet speed test didnt get impacted much, i still get 930/900 (Download/Upload) speed .

I didnt do port swapping to validate is the ONT port is broken.

Look like SingTel update its IPTV settings, turning on IGMp snooping will cause freezing frames, video keep pausing issue.

No choice, have to update settings to get IPTV to work.
