* Note:  If you set the rising threshold value and the falling threshold 

value close together, events may be logged more often if the 
Notify option is selected.

* Note:  No configuration event is generated in the event log when you 

enable or disable NEDR. However, you can find out which 
ports have NEDR enabled by using show port network-error-
detection CLI command.

action {notify | disable-port 
| off}

Action that NEDR performs when the rate of 
errors exceeds the threshold. The options are:

• notify—Logs the event in the event log

• disable-port—Disables the port and logs 

the event in the event log. A port is 
disabled if the rate of errors equals or 
exceeds the threshold. Make sure a 
redundant protocol is configured.

• off—Disables NEDR on the port or ports 

that you specify. 

The default setting is notify.

The rising threshold. 

The number of CRC errors that triggers NEDR to 
log an event in the event log or disable the port. 
The default setting is 100 (minimum is 1; 
maximum is 65535).

The falling threshold. 

After exceeding the rising threshold, NEDR does 
not log another event in the event log until the 
rate of CRC errors falls below the falling 
threshold and then exceeds the rising threshold 
again. The default setting is half the rising 
threshold value (minimum is 0; maximum is 
65535).

How often NEDR checks the number of errors 
occurring against the thresholds. Enter a number 
of seconds. 

The default setting is 2 seconds (minimum is 1; 
maximum is 65535).
