Tp-link t1700-28tq vlans and lag/lacp

[Drewy]

I'm having issues with vlans over aggregated links, both static lag and lacp.

Been trying to get some vlans out to my quanta lb6m from the tp-link without success. Initially thought it was my vlan configuration on the lb6m but as part of my debugging efforts I've tried a lag and vlan setup over ethernet to a dlink switch.
I can get the vlans to pass just fine over a single link but the second I turn that link into a lag I loose the vlans and haven't managed to get them back. Removing a link and dropping the lag returns the traffic.

Has anyone had similar issues with the tp-link switch?

This may or may not apply to the tp-link, but it sounds like it might. It would apply in Cisco land, and with other gear as well. Typically vlan configuration must made to a LAG interface, and not on the actual member interface. I usually mirror the same configuration on the member ports as well as the Port-channel interface.

If I remember correctly Juniper actually forces you to remove all configuration from the member interfaces, and only assign config to the new LAG interface (ae0.x).

Thanks for the reply, however I don't think that's the issue here. With both the tp-link and the dlink switches I have you still assign the vlan config to the member interfaces rather than the LAG. In fact there isn't the concept of a LAG while assigning vlans.
This worked fine dlink to dlink.

Hey Aero....

Turns out you are actually right!

The web gui is busted with the t1700-28tq. After much playing and testing I noticed that the default vlan 1 actually shows a port channel + the individual ports when added to a LAG. However adding any other vlans to that LAG only adds the ports and not the port channel.

But I could manually add the port-channel via cli. It then shows up via the web gui and traffic flows...

Apologies for doubting your wisdom

You're welcome, I'm glad the advice was helpful. I'm always a bit wary of the GUIs on consumer/pro-sumer gear. Lucky those tp-links have a real CLI!
