Use the undo oam errored-frame-seconds period command to restore the default. 
By default, the errored frame seconds detection interval is 60 seconds. 
A errored frame seconds event occurs when a errored frame seconds detection interval expires and the 
number of the error seconds of an Ethernet port is larger than (or equal to) the errored frame seconds 
event triggering threshold. (A second is called an error second if error frames occur in the second.) 
The errored frame seconds detection interval configured applies to all the Ethernet ports on which 
Ethernet OAM connections are established.

2: System level 
Parameters 
threshold-value: Errored frame seconds event triggering threshold, ranging from 0 to 900.  
Description 
Use the oam errored-frame-seconds threshold command to set the errored frame seconds event 
triggering threshold. 
Use the undo oam errored-frame-seconds threshold command to restore the default. 
By default, the errored frame seconds event triggering threshold is 1.  
A errored frame seconds event occurs when a errored frame seconds detection interval expires and the 
number of the error seconds of an Ethernet port is larger than (or equal to) the errored frame seconds 
event triggering threshold. (A second is called an error second if error frames occur in the second.) 
The errored frame seconds event triggering threshold configured applies to all the Ethernet ports on 
which Ethernet OAM connections are established.
