NETGEAR 8800 Chassis Switch CLI Manual Default Depending upon your platform, the following defaults apply: • If backplane diagnostics are enabled on a particular slot, the default for sending packets is 5 seconds on that slot. • The polling interval is always 5 seconds (this is a not a user-configured parameter). Usage Guidelines Use this command with the guidance of NETGEAR Technical Support personnel. The system health checker tests I/O modules and the backplane by forwarding backplane diagnostic packets. Use this command to configure the amount of time it takes for the packets to be forwarded and returned to the MSM. To enable backplane diagnostic packets, use the enable sys-health-check slot command. With backplane diagnostic packets enabled on a specific slot, the interval option of the configure sys-health-check interval command specifies the frequency of sending backplane diagnostic packets. For example, if you specify an interval of 9, backplane diagnostic packets are sent every 9 seconds on only the enabled slot. Note: NETGEAR does not recommend configuring an interval of less than the default interval. Doing this can cause excessive CPU utilization. By default, the system health checker always polls the control plane health between MSMs and I/O modules, monitors memory levels on the I/O module, monitors the health of the I/O module, and checks the health of applications and processes running on the I/O module. If the system health checker detects an error, the health checker notifies the MSM. You must enable the backplane diagnostic packets feature to send backplane diagnostic packets. If you enable this feature, the system health checker tests the data link for a specific I/O module every 5 seconds by default. The MSM sends and receives diagnostic packets from the I/O module to determine the state and connectivity. If you disable backplane diagnostics, the system health checker stops sending backplane diagnostic packets. Example The following examples assume that you enabled backplane diagnostic packets on a specific I/O slot. On the NETGEAR 8800 series switches, the following command configures the backplane diagnostic packet interval to 8 seconds: configure sys-health-check interval 8 configure sys-recovery-level configure sys-recovery-level [all | none] Chapter 8.

Commands for Status Monitoring and Statistics

NETGEAR 8800 Chassis Switch CLI Manual

Default

Depending upon your platform, the following defaults apply:

•

If backplane diagnostics are enabled on a particular slot, the default for sending

packets is 5 seconds on that slot.

•

The polling interval is always 5 seconds (this is a not a user-configured parameter).

Usage Guidelines

Use this command with the guidance of NETGEAR Technical Support personnel.

The system health checker tests I/O modules and the backplane by forwarding backplane

diagnostic packets. Use this command to configure the amount of time it takes for the

packets to be forwarded and returned to the MSM.

To enable backplane diagnostic packets, use the

enable sys-health-check slot <slot>

command. With backplane diagnostic packets enabled on a specific slot, the

interval

option

of the

configure sys-health-check interval

command specifies the frequency of sending

backplane diagnostic packets. For example, if you specify an interval of 9, backplane

diagnostic packets are sent every 9 seconds on only the enabled slot.

Note:

NETGEAR does not recommend configuring an interval of less than

the default interval. Doing this can cause excessive CPU utilization.

By default, the system health checker always polls the control plane health between MSMs

and I/O modules, monitors memory levels on the I/O module, monitors the health of the I/O

module, and checks the health of applications and processes running on the I/O module. If

the system health checker detects an error, the health checker notifies the MSM.

You must enable the backplane diagnostic packets feature to send backplane diagnostic

packets. If you enable this feature, the system health checker tests the data link for a specific

I/O module every 5 seconds by default. The MSM sends and receives diagnostic packets

from the I/O module to determine the state and connectivity. If you disable backplane

diagnostics, the system health checker stops sending backplane diagnostic packets.

Example

The following examples assume that you enabled backplane diagnostic packets on a specific

I/O slot.

On the NETGEAR 8800 series switches, the following command configures the backplane

diagnostic packet interval to 8 seconds:

configure sys-health-check interval 8

configure sys-recovery-level

configure sys-recovery-level [all | none]
