Per-Slot Packet Memory Scan on BlackDiamond
Switches
While the system health check auto-recovery mode is effective at recovering from suspected failures, it
does not provide the depth of control over recovery options that many network administrators require.
The per-slot packet memory scan capability on BlackDiamond switches gives administrators the ability
to set the recovery behavior for each module—an important distinction when only certain modules can
be taken offline, while others must remain online no matter what the error condition.
NOTE
This capability is available only on BlackDiamond switches.
You can scan and check the health of individual BlackDiamond modules rather than the entire system
by configuring packet memory scanning on a per slot basis. When you have the system health check
facility configured for auto-recovery and you configure packet memory scanning on a BlackDiamond
slot, you can define the behavior to be applied to the module in that slot when an error is detected. By
default, packet memory scanning on a per slot basis is disabled.

Configuring the Packet Memory Scan Recovery Mode
To configure packet memory scanning on a BlackDiamond module, use this command:
configure packet-mem-scan-recovery-mode [offline | online] slot [msm-a | msm-b | <slot number>]
where:
NOTE
The setting values for this command override the settings in the global system health check
auto-recovery configuration. If you have the system health check alarm-level option configured, the
per-slot packet memory scanning configuration is ignored. For more information about the system health
check facility, see
“System (CPU and Backplane) Health Check” on page 70 .
offline
Specifies that a module is to be taken offline and kept offline when one of these
conditions is true:
• More than eight defected are detected.
• No new defects were found by the memory scanning and mapping process.
• The same checksum errors are again detected by the system health checker.
online
Specifies that a faulty module is to be kept online regardless of any errors detected.
msm-a
Specifies the MSM installed in slot A.
msm-b
Specifies the MSM installed in slot B.
slot number
Specifies the module installed in a particular slot.
