configure sys-recovery-level

configure sys-recovery-level [all | none]

Description

Configures a recovery option for instances where a software exception occurs in ExtremeXOS.

Syntax Description

all	Configures ExtremeXOS to log an error into the syslog and reboot the system after any software task exception occurs.
none	Configures the recovery level to none. No action is taken when a software task exception occurs; there is no system reboot, which can cause unexpected switch behavior. Note: Use this parameter only under the guidance of Extreme Networks Technical Support personnel.

Default

The default setting is all.

Usage Guidelines

If the software fails, the switch automatically reboots or leaves the system in its current state. You must specify one of the following parameters for the system to respond to software failures:

all—The system will send error messages to the syslog and reboot if any software task exception occurs.

On modular switches, this command sets the recovery level only for the MSMs/MMs. The MSM/MM should reboot only if there is a software exception that occurs on the MSM/MM. The MSM/MM should not reboot if a software exception occurs on an I/O module.

To set the recovery level for all slots (MSM/MM and I/O) use the configure sys-recovery-level slot command.
none—No action is taken when a software task exception occurs. The system does not reboot, which can cause unexpected switch behavior.
Note

Use the none parameter only under the guidance of Extreme Networks Technical Support personnel.

The default setting and behavior is all. Extreme Networks strongly recommends using the default setting.

Displaying the System Recovery Setting

To display the software recovery setting on the switch, use the following command:

show switch

This command displays general switch information, including the software recovery level. The following truncated output from a Summit switch displays the software recovery setting (displayed as Recovery Mode):

SysName:          TechPubs Lab
SysLocation:
SysContact:       support@extremenetworks.com, +1 888 257 3000
System MAC:       00:04:96:20:B4:13
SysHealth check:  Enabled (Normal)
Recovery Mode:    All
System Watchdog:  Enabled

Note

All platforms display the software recovery setting as Recovery Mode.

Example

The following command configures a switch to not take an action when any software task exception occurs:

configure sys-recovery-level none
