Hello. I have a problem with C2960 switches after upgrading the firmware on c2960-lanbasek9-mz.150-2.SE7.
1. On the switch WS-C2960-24PC-L lost all copper ports, optics works. after downgrading to the previous firmware versions (including c2960-lanbasek9-mz.122-50.SE5) the problem remained.

2. On all switches with 48 ports (in particular WS-C2960+48PST-L) is a critical memory load, as a result, they are not accessible via SSH and via console, 802.1x did not work. After downgrading firmware on the switches were observed cyclic reboot. Helped firmware c2960-lanbasek9-mz.122-50.SE5.
What could be the problem and how to solve it?
