set errordetection
Defaults The following are the default settings for set errordetection:
•Inband error detection is enabled.
•Memory error detection is enabled.
•Portcounters error detection is enabled.
•Packet-buffer error detection is errdisable.
•Link-error error detection is port-failover.
•The link-error interval is 30 seconds.
•The high value for the inerrors threshold is 1001 packets.
•The low value for the inerrors threshold is 1000 packets.
•The high value for the rxcrc threshold is 1001 packets.
•The low value for the rxcrc threshold is 1000 packets.
•The high value for the txcrc threshold is 1001 packets.
•The low value for the rxcrc threshold is 1000 packets.
•The link-error sampling is 3 times.
Command Types Switch command.
Command Modes Privileged.
Usage Guidelines The set errordetection command is useful for monitoring the switch. If an error is detec ted, a sysl og
message informs you that a problem exists before noticeable performance degradation occurs. For
example, entering these commands displays the following informa tio n:
•set errordetection inband—Displays the type of inband failure occurrence, such as inband stuck,
resource errors, and inband fail when you start the switch.
•set errordetection memory—Displays the address where the memory corruption occurred.
•set errordetection portcounters—Displays the module and port number and the counter that had
the problem between two consecutive polls.
Inband, memory, and portcounter error detection is enabled by default in release 8.4(2 ) and later releases.
The rapid boot feature minimizes the amount of downtime a module experiences if the module
encounters a packet-buffer error. You can enter one of the following commands to handle the error
condition:
•set errordetection packet-buffer errdisable—If you enter the errdisable keyword, only ports that
experience the packet-buffer error are put in errdisable state.
•set errordetection packet-buffer powercycle—If you enter the powercycle keyword, the module
is power cycled. When you choose this option, a ROMMON image is downlo ad ed on the m od ule,
and the normal bootup sequence is bypassed to reduce module downtime.
Caution Do not power cycle the module when the ROMMON image is downloading. Doing so might damage the
module.
