disable sys-health-check

disable sys-health-check slot slot


Discontinues sending backplane diagnostic packets on modular switches.

Syntax Description

slot Specifies the slot to disable sending backplane diagnostic packets.


Polling is enabled, backplane diagnostic packets are disabled.

Depending upon your platform, when disabling backplane diagnostic packets, the following defaults apply:
  • BlackDiamond 8800 series switches—By default, the system health checker discontinues sending backplane diagnostic packets to the specified slot. Only polling is enabled.

Usage Guidelines

When you use this command, backplane diagnostic packets are disabled and no longer sent by the system health checker.

BlackDiamond 8800 Series Switches Only

If you modify the interval in the configure sys-health-check interval interval command and later disable backplane diagnostics, the configured interval for sending backplane diagnostic packets remains. The next time you enable backplane diagnostic packets, the health checker sends backplane diagnostics packets at the configured interval. For example, if you configure an interval of 8seconds, the system health checker sends backplane diagnostic packets every 8seconds.

To return to the "default" interval of 5seconds, configure the frequency of sending backplane diagnostic packets to 5 seconds using the following command:

configure sys-health-check interval 5


On the BlackDiamond 8800 series switches, the following example assumes that you did not modify the interval option in the configure sys-health-check interval interval command.

The following example disables backplane diagnostics on slot 3, polling is always enabled and occurs every 5 seconds.

disable sys-health-check slot 3


This command was first available in ExtremeXOS 10.1.
