Enable ethernet-oam of Ethernet 1/4.
Switch(config)#interface ethernet 1/4
Switch(Config-If-Ethernet1/4)#ethernet-oam
11.7 ethernet-oam errored-frame threshold high
Command:
ethernet-oam errored-frame threshold high {<high-frames> | none}
no ethernet-oam errored-frame threshold high
Function:
Configure the high threshold of errored frame event, no command restores the default value.
Parameters:
<high-frames>, the high detection threshold of errored frame event, ranging from 2 to 4294967295.
none, cancel the high threshold configuration.
Command Mode:
Port mode
Default:
none.
Usage Guide:
During the specific detection period, serious link event is induced if the number of errored frame is larger than or
equal to the high threshold and the device notifies the peer by sending Information OAMPDU of which the value of
Link Fault flag in Flags field is 1. Note that the high threshold can not be less than the low threshold.
Example:
Configure the high threshold of errored frame event on Ethernet 1/4 to be 3000.
Switch(Config-If-Ethernet1/4)#ethernet-oam errored-frame threshold high 3000
11.8 ethernet-oam errored-frame threshold low
Command:
ethernet-oam errored-frame threshold low <low-frames>
