Our switch got reloaded once, after reload we found that "ip dhcp snooping trust" command disappeared from physical interfaces.
Tried to find a bug related to the same software but couldn't find.
IOS version: 15.2(3)E
HW model: 3560x
It could be that the configuration was not saved and after the reboot the switch went back to an older config that did not have "ip dhcp snooping trust" configuration.
Thanks Reza, the configurations were saved already, although configurations were disappeared from physical interfaces, it was still there on the PO level, but not working.
Did the switch reloaded on its own, or this was a manual reboot? If it reloaded on its own, is there crash file written on the flash? If it did than there maybe an IOS bug that is causing it to reboot. Anything in the logs?
