Port is down but its state changes through high traffic alert

There are disabled port down alerts except network ports with ifAlias included 'p_mon' tag ('Port down alert checker.PNG' image in attach)
There are few ports which are down for a long time and they are in this state (sfp module not inserted).
Also there is high traffic on interface alert checker ('High traffic alert checker.PNG' image in attach).
These ports alertsare suppressed by "Ignore untill ok".
So on some reason such port which is down for a long time gets alert about high traffic on interface (but port is down!), then port marked as up by this alert and then we have alert that port is down ('Alert log.PNG' in attach).
I checked counters just in case, but there are no counts (screen in attach 'Port data.PNG')
