Enabling Diagnostic Packets on the Switch--Modular Switches Only

Enable diagnostic packets with the command:
enable sys-health-check slot slot

For BlackDiamond 8800 and BlackDiamond X8 series switches, the system health checker tests the data link by default.

The 10 Gbps links (BlackDiamond 8000 a-, c-, e-, xl-, and xm-series modules)—the system health checker tests every five seconds for the specified slot.



Enabling backplane diagnostic packets increases CPU utilization and competes with network traffic for resources.
