disable card-scan
Description
Disables the card-scan feature on MSM slots in the BlackDiamond switch.
Syntax Description
This command has no arguments or variables.
Default
By default, card-scan is enabled.
Usage Guidelines
On certain BlackDiamond switches running earlier releases of ExtremeWare, hot insertion of a slave
MSM causes one or more of the following conditions:
• Some or all of the I/O modules are reset.
• The front panel links go down on some or all of the I/O modules.
• The backplane links go down on some or all of the I/O modules.
The card-scan feature discovers and repairs this condition, thus preventing the need for a manual reset
of the switch. When card-scan is enabled, the system logs one of the following messages if a problem
occurs when the MSM is inserted:
Cardscan (msm insert) Attmpting to fix broken BP connection for slot x
Cardscan (msm insert) Attmpting to fix packet missed for slot x
Cardscan (msm insert) Attmpting to fix card x in reset (y)
Cardscan (timer) Attmpting to fix card x in reset (y)
In these messages, represents a slot number and represents debugging information.
x y

The following command disables card-scan:
