Dear all,
3 switches SX500-XG are linked through a fiber optical modules without make a loop.
From many weeks a STP Warning (See bellow) comes. It doesn't matter for 90% of network device connected on 2 switches but for 5% of them, it makes some troubles that not appreciate that their network connection comes down and up in 3 seconds. I'm looking to on Internet and here if someone have the same issue but it's not clear for me but I think it should be a simpl issue to resolve. I'm a begineer and it's why I join to this message the 2 switches configurations and 2 diagnostics files get from the same devices.
Hoping it will talk to you better to me.
Thanks of lot for your support.
Kind regards,
Alain
