Netgear XCM8806 - 8800 SERIES 6-SLOT CHASSIS SWITCH ユーザーズマニュアル

NETGEAR does not recommend configuring an interval of less than 

5 seconds. Doing this can cause excessive CPU utilization.

Building upon the previous example, the following example disables backplane diagnostics 
on slot 3:

disable sys-health-check slot 3

Backplane diagnostic packets are no longer sent, but the configured interval for sending 
backplane diagnostic packets remains at 7 seconds. The next time you enable backplane 
diagnostic packets, the health checker sends the backplane diagnostics packets every 
7 seconds. 

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

configure sys-health-check interval 5

Setting the System Recovery Level

Depending on your switch model, you can configure the switch, MSM/MM, or I/O module to 
take action if a fault detection exception occurs. The following sections describe how to set 
the software and hardware recovery levels on the switch, MSM/MM, and I/O modules.

This section describes the following topics: 

•     Configuring Software Recovery 

•     Configuring Module Recovery 

Configuring Software Recovery

You can configure the system to either take no action or to automatically reboot the switch 
after a software task exception, using the following command:

configure sys-recovery-level [all | none]

Where the following is true: 

all

—Configures XCM8800 to log an error to the syslog and automatically reboot the 

system after any software task exception.

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. 

none

—Configures the system to take no action if a software task exception occurs. The 

system does not reboot, which can cause unexpected switch behavior.
