hello,

i have 1930 switches connected to 6200 core SW redundant, 

the 1930 indicating loop that is happening somewhere, i have enabled loop protection, MSTP, BPDU Filter, and root guard on all switches, 

is there any other option to be enabled on the 1930 sw to avoid loop and network flapping?

thanks!!

Hi,

It sounds like you have, two or more ethernet connecting your 1930 to your 6200 switch, is that correct?

If so you might need to configure a lagg / lacp group to allow multiple links to act as a bond

Hello Travatine,

yes, i have already configured lags and lacp, and all configured correctly,

i just need to know if there is additional features that should be turned on 1930 SW to avoid such issues,
