Hello Everyone,
I got many snmp alert from WS-C4500X-32, for example Te1/1/2 Optical RX is to low (-40).
Which is wired, I have never connected SFP modul at this port, and the ports config is empty.
But, if I checked the inventory the switch says the SFP moduls details, and the port phisicaly empty.
I attached some log.
