The Network Error Detection and Recovery (NEDR) feature monitors Ethernet CRC errors on Ethernet data ports and compares the rate of errors that occurs to the threshold values that you set. This feature helps you find the source of the errors and take corrective action if necessary.
If the rate of CRC errors equals or exceeds the threshold value, the NEDR feature can:
Note: The Link LED on the 10-Gigabit module does not indicate a disabled status. The LED should flash green when you or the Network Error Detection and Recovery (NEDR) feature disable the port. However, the LED remains solid green.
If NEDR shuts down a port, the switch will forward traffic through a redundant port if you:
If you do not enable a protocol that supports redundancy on the port and provide an alternate path, you may lose traffic if the port shuts down.
If you replace a module that has a port that NEDR has disabled, the switch will load the startup configuration for the module and reenable the port. However, if you save the running configuration to the startup configuration while a port is shut down, you will have to manually reenable the port after you replace the module or reset the switch.
To reenable a turned off port, use the set port enable CLI command.
