Hello, I have a switch
Model: WS-C3750-48PS-S
IOS version: c3750-ipbasek9-mz.122-55.SE10.bin
It continuosly resets. I downgrade to c3750-ipbasek9-mz.122-35.SE5.bin and stops the reboot. The equipment works properly
Anyone have any idea why this happens ?
Sorry but my English ir very bad.
Thanks.
This is the log output
%Software-forced reload
