M4300-12X12F - LAG State Admin Mode D-Disable
Hi, I have 2 M4300-12X12F in stack.
After this error "Diagnostically disabling interface lag 8 as rate limit of 15 for 3 consecutive seconds has been exceeded"
I found both ports included in the LAG with admin mode disabled and the LAG State in D-Disabled mode.
I managed to re-enable Admin mode in switching -> ports -> admin mode but LAG State remains in D-Disable. In switching -> LAG i try to change LAG State in Admin Mode enabled but the change is not saved.
How can I reactivate the LAG without restarting the switch?

Hi xw32
Welcome to Community!
How about your network topology? Is there loop connect? D-disable status may be casued by spanning-tree detect there is a loop.

Hi, both ports number 3 of the netgear switch went into block were attached in lag towards an HP aruba switch, I am attaching a diagram of how the various switches are connected; the loop was probably generated by a switch3 reset procedure (HP).
thanks for the support
Yes, I see both port 1/0/3 and 2/0/3 connect to switch2, and it will cause loop, Loop Protection will D-disable some port when detect loop. Is it necessary to connect two ports(1/0/3, 2/0/3) to switch2? Is it possible binding two ports as a lag?
And what about other port connection? such as lag1..lag8?
Could you please command as 'show spanning-tree summary' and 'show spanning-tree mst port summary 0 active', and print the output info here? I want to check which ports is discarding status.
