I have two cisco catalyst 9300 series switches which are connected to each other over te1/1/1.
The problem is that when I e.g. perform a reload on one switch (switch-01) I get an err-disable on (switch-02)
ERR_DISABLE udld error detected on Te1/1/1, putting Te1/1/1 in err-disable state
And this port stays in this state until I perform a shutdown and no shutdown.
Is there any comfiguration Point to blame this symptom?
