Parameters
high-threshold
high-value
: Specifies the upper threshold for CRC error packet alarms. If
you specify the
ratio
keyword, the value range is 1 to 100. If you do not specify the
ratio
keyword, the value range is 1 to 4294967295 packets.
low-threshold
low-value
: Specifies the lower threshold for CRC error packet alarms. If you
specify the
ratio
keyword, the value range is 1 to 100. If you do not specify the
ratio
keyword,
the value range is 1 to 4294967295 packets.
interval
interval
: Specifies the statistics collection and comparison interval for CRC error
packets, in the range of 1 to 65535 seconds.
shutdown
: Shuts down an interface when the number of incoming CRC error packets on the
interface exceeds the upper threshold. Then, the interface stops forwarding all packets. To recover
the interface, execute the
undo shutdown
command on the interface. If you do not specify this
keyword, an upper threshold exceeding alarm is generated and the interface enters the alarm state
when the number of incoming CRC error packets exceeds the upper threshold on the interface.
Usage guidelines
With the CRC error packet alarm function enabled, when the number of incoming CRC error packets
on an interface in normal state within the specified interval exceeds the upper threshold, the interface
generates an upper threshold exceeding alarm and enters the alarm state. When the number of
incoming CRC error packets on an interface in the alarm state within the specified interval drops
below the lower threshold, the interface generates a recovery alarm and restores to the normal state.
You can configure the CRC error packet alarm parameters in system view and interface view.
•
The configuration in system view takes effect on all interfaces of the specified slot. The
configuration in interface view takes effect only on the current interface.
•
For an interface, the configuration in interface view takes priority, and the configuration in
system view is used only when no configuration is made in interface view.
When you execute this command multiple times, the most recent configuration takes effect.
Examples
# Set the upper threshold to 5000, lower threshold to 400, and statistics collection and comparison
interval to 6 seconds for CRC error packet alarms on GigabitEthernet 1/0/1.
