Configuring Ports
Hardware Support
You can enable NEDR only for ports on gigabit and 10-gigabit Ethernet
modules and only by using CLI commands. You cannot enable the feature
on any other types of ports, for example, Ethernet 10/100, ATM Uplink, or
supervisor, and cannot enable the feature by using the Web Agent.
* Note: If the switch has an 80-series supervisor module installed,
monitoring begins as soon as you turn on the switch. If the
switch has a layer 3 supervisor module installed, monitoring
may not begin until approximately 35 seconds after you turn
on the switch.
Example
Figure 8-13. Example of How NEDR Works
In Figure 8-13 , 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.
Enabling NEDR
You can enable NEDR only for ports on gigabit and 10-gigabit Ethernet
modules and only by using CLI commands.
To enable NEDR:
1. Enter Global Configuration mode.
The CLI displays the
(configure)#
prompt.
2. Enter the following command:
set port network-error-detection {<mod-port-range> | all}
[action {notify | disable-port | off}] [rising-threshold <rising-
threshold-value>] [falling-threshold <falling-threshold-value>]
[interval <interval-seconds>]
