Hello Everyone,

 

We are really struggling with setting up a LAG between our 2 switches.

 

When setting the LAC up (static or LACP) the network goes down immediately (probably broadcast storm).

 

We have set the LAG up according to the TP-link instructions given in the manual and online forums.

 

In the MENU, we went to L2 features, LAG and have chosen LACP.

 

Group ID 1 - enable - 32768 - Active and have chosen ports 23 en 24

 

on the second witch we have done the same and chosen ports 1 and 2.

 

Immediatly after hitting save, the network goes down with the 2 links inserted...  configuring a static LAN gives the same result.

 

Has someone more experience with this setup ?

 

thanks,

David

You can check the LED to confirm whether it's a broadcast storm. If the LED did not flash quickly. I think your problem may be caused by the setting for LAGS. 

For tp-link switch, after you set up LAG, you need to re-configure layer 2 function for LAG group. The original configuratrion for the switch ports will out of action. So you lost network maybe because you haven't configured layer2 function for LAG group.

The following is the FAQ for configuration VLAN for LAG. Other layer2 function is similar.
