Cisco Switch SG550X Issue

Has anyone have experienced working with this Cisco switch?

I could not get the ssh working on this switch at all. The dedicated g1/0/1 for management access and made the interface layer3, but the uplink switch (Juniper) keeps disabling the edge port because it keeps receiving BPDU from the Cisco g1/0/1. As far as I know, once the switchport become layer3 (no switchport) it will no longer participate to STP.

interface gigabitethernet1/0/1 IP address 192.168.0.2 255.255.255.240 No switchport 

What is happening now is the port g1/0/1 is flapping.
