Configuring Port Parameters
* Note: You can reenable the turned off port by entering
the following CLI command:
set port enable
NEDR does not check for an available redundant port
or for a redundant protocol running on the port. You
must create a redundant path. Traffic loss will occur if
a redundant path is not available.
■
Log the event in the Event Log
If you replace a module that has a port that has been disabled by
NEDR, 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.
Example
Figure 6-10. Example of How NEDR Works
In 6-10, the rising threshold is set to 1000, and the falling threshold
is set to 500. The first time that the rate of CRC errors exceeds the
rising threshold, NEDR logs the event in the event log or disables the
port. If you set the feature to notify, NEDR does not log another
event until the rate of CRC errors drops below the falling threshold
and then exceeds the rising threshold again. If you set NEDR to
disable-port, the feature disables the port the first time that the
rate of CRC errors exceeds the rising threshold. The port remains
disabled until you reenable it, or until you remove and replace/
reinsert a module of the exact type.
