Hope someone can assist. Am having an issue with our 3650 connection. Have already replaced the SFP and still having connection issues. Am getting reliability of either 241/255 or 245/255. Am thinking it is possibly the fiber. Below is the result of sh interface 1/1/4
Gi1/1/4 connected trunk full 1000 1000BaseSX SFP
3650-48#sh int gi1/1/4
GigabitEthernet1/1/4 is up, line protocol is up (connected)

Also, under the setting for the GigabitEthernet1/1/4, if I remove speed nonegotiate, I will lose my connection. Below is the setting. None of the other 3650's have this setting :
interface GigabitEthernet1/1/4
description ** Verizon **
switchport trunk allowed vlan 74
switchport mode trunk
speed nonegotiate
Thanks for the assist.
