configure sys-recovery-level switch

configure sys-recovery-level switch [none | reset | shutdown]

Description

Configures a recovery option for instances where a hardware exception occurs on ExtremeSwitching series switches.

Syntax Description


none	Configures the switch to maintain its current state regardless of the detected fault. The switch does not reboot or shutdown. ExtremeXOS logs fault and error messages to the syslog.
reset	Configures the switch to reboot upon detecting a hardware fault. ExtremeXOS logs fault, error, system reset, and system reboot messages to the syslog.
shutdown	Configures the switch to shut down upon detecting a hardware fault. All ports are taken offline in response to the reported errors; however, the management port remains operational for debugging purposes only. If the switch shuts down, it remains in this state across additional reboots or power cycles until you explicitly clear the shutdown state.

Default

The default setting is reset.

Usage Guidelines

Use this command for system auto-recovery upon detection of hardware problems. You can configure ExtremeSwitching series switches to take no action, automatically reboot, or shutdown if the switch detects a hardware fault. This enhanced level of recovery detects faults in the CPU.

You must specify one of the following parameters for the switch to respond to hardware failures:

none—Configures the switch to maintain its current state regardless of the detected fault. The switch does not reboot or shutdown.
reset—Configures the switch to reboot upon detecting a hardware fault.
shutdown—Configures the switch to shutdown upon fault detection. All ports are taken offline in response to the reported errors; however, the management port remains operational for debugging purposes only.

Messages Displayed

If you configure the hardware recovery setting to either none (ignore) or shutdown, the switch prompts you to confirm this action by displaying a message similar to the following:

Are you sure you want to shutdown on errors? (y/n)

Enter y to confirm this action and configure the hardware recovery level. Enter n or press [Enter] to cancel this action.

Displaying the Hardware Recovery Setting

To display the hardware recovery setting, use the following command:

show switch

If you change the hardware recovery setting from the default (reset) to either none (ignore) or shutdown, the Recovery Mode output is expanded to include a description of the hardware recovery mode. If you keep the default behavior or return to reset, the Recovery Mode output lists only the software recovery setting.

The following truncated output from a ExtremeSwitching series switch displays the software recovery and hardware recovery settings (displayed as Recovery Mode):

SysName:          TechPubs Lab
SysLocation:
SysContact:       support@extremenetworks.com, +1 888 257 3000
System MAC:       00:04:96:1F:A5:71
Recovery Mode:    All, Ignore
System Watchdog:  Enabled

If you configure the hardware recovery setting to none, the output displays “Ignore” to indicate that no corrective actions will occur on the switch. “Ignore” appears only if you configure the hardware recovery setting to none.

If you configure the hardware recovery setting to shutdown, the output displays “Shutdown” to indicate that the switch will shutdown if fault detection occurs. “Shutdown” appears only if you configure the hardware recovery setting to shutdown.

If you configure the hardware recovery setting to reset, the output displays only the software recovery mode.

Example

The following command configures the switch to not take an action if a hardware fault occurs:

# configure sys-recovery-level switch none
