ok im on xr500 and latest stable openwrt - never had any problems with my iptv stb on vlan6 , but that dsa upgrade is nighmare - ok ive got it somehow working with vlan filtering on br-lan but with some freezes etc, ok ive tried remove stb port from br-lan to separate bridge , lan port is dead if theres no interface , ok bringing up dummy iterface breaks my internet .how to get that thing going like it was before dsa ?
Let's see your conifg...
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button (red circle; this works best in the 'Markdown' composer view in the blue oval):
Remember to redact passwords, VPN keys, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/network
Question was more about how to get simple vlan6 pipe from wan to lan port1 get going. Stb expects untaged pockets .
Edit: vlan filtering on br-lan wotks, but with freezes
Use bridge VLANs. Add the wan port to the bridge (likely br-lan; don't forget to remove it from the wan/wan6 interfaces) and then setup 3 VLANs.
You can use other VLAN IDs, if you want, but...
- VLAN 1 will be your lan and likely serves ports lan2-lan4 (assuming 4 lan ports on your device), set as untagged +PVID on all 3 ports.
- VLAN 2 will be your wan, presumably untagged on the wan port.
- VLAN 6 will be IPTV, presumably tagged on the wan port and (assuming the untagged expectation is correct) untagged + PVID on port lan1.
Thats my current somehow working config with br-lan vlan filtering - vlan1 for lan, vlan6 for iptv and vlan10 for wan. Its working but with freezes on my stb. So idea was to remove lan port1 from br-lan and make separate iptv bridge if that helps. Problem is that port1 has no link if its removed from br- lan and has no interface even if its added to new iptv bridge
You need everything on the same bridge because you're passing VLAN 6 through from the wan to port lan1.
Let's see that config.
As i said its working with vlan filtering enabled on br-lan , but stb can play happy for hours then freeze , channel change , video is going for few seconds, freeze , ect… never had any problems with switch config so thats clearly dsa problems
Without seeing your config, I don't agree that this is a DSA problem.
I have helped people configure both DSA and swconfig and I have rarely seen any issues attributable to the switch configuration method itself (i.e. DSA vs swconfig) but I've seen lots of issues caused by configuration errors.
Ok, lets hope its config problem, ill post my network config later ( as im in bed now) but i cant see how its can be wrong if i can watch my iptv for hours and then its freezes
We'll wait to see your config... post it when you can.
The other thing you might check is to see if the STB actually might want VLAN 6 tagged and/or if there are any other things happening with the STB itself that could account for the problem.
It's not clear to me if you're using a new router or if you've just upgraded an existing one from a release that was swconfig based to DSA... if this is a replacement, maybe stick the old one in place for a long enough to verify that the STB doesn't have any other issues.
Router is netgear xr500 ( aka 7800) flashed from dumaos to openwrt latest stable. Never had any problems with vlan6 iptv before so its clearly dsa problem, ive used older openwrt with switch config and tplink 3600 router and had 0 problems with iptv too
Well, let's reserve judgement for "DSA" being the reason for the problem until we have evaluated the config to ensure that it is configured properly.
If stb can get ip and boot from isp vlan6 - network config is ok 100%, problem is in multicast querier, snooping ,.ageing or holy water lack maybe.
Assuming that you simply need to pass the VLAN through from the wan, there should be nothing more than a bridge-VLAN setup... but we need to see the config.
yep, simple wan.6 to lan port 1 untaged
Again... let's see the config... the description is not sufficient.
Note: I edited the thread topic. Even if facetious, references to self-harm are not appropriate for a community forum.
Install package ip-bridge to get the bridge command, then run bridge -d vlan show to see how the DSA bridge is actually set. Post the results. Properly working DSA should use hardware switching like swconfig does so there should be no difference in performance.
If you still have your 3600 you could configure it to be only a managed switch to split out the TV VLAN before your router. Or of course use any other managed switch.
Yep ive managed switch that could be used in this situation, but goal is to configure main router for that - do i still need querier if its just pipe for stb. ? Looks like its working now , got no freezes at the moment
I suggest using a separate switch as a test in case there may be some other problem with the TV box or service itself.
I think the default in a DSA bridge is to pass all multicast. That doesn't hurt anything here since there are only two ports and its confined to a separate VLAN.
