NETGEAR 8800 Chassis Switch CLI Manual Usage Guidelines This command enables sFlow on a particular list of ports. You also need to enable sFlow globally in order to gather statistics and send the data to the collector. Once sFlow is enabled globally, and on the ports of interest, sampling and polling begins. Use the following command to enable sFlow globally: enable sflow Example The following command enables sFlow sampling on the port 3:1: enable sflow ports 3:1 enable sys-health-check enable sys-health-check slot Description Enables backplane diagnostic packets on the specified slot. Syntax Description slot Specifies the slot to participate in sending backplane diagnostic packets. Default Polling is enabled, backplane diagnostic packets are disabled. Depending upon your platform, when you enable diagnostic packets, the system health checker tests the data link every 5 seconds for the specified slot. Usage Guidelines Configure the system health checker with guidance from NETGEAR Technical Support personnel. The system health checker tests I/O modules and the backplane by sending diagnostic packets. By isolating faults to a specific module or backplane connection, the system health checker notifies you of a possible hardware failure. System health check errors are reported to the syslog. Syslog output includes the slot number where the problem occurred, the loopback packet ID number, and a notification that the MSM/MM did not receive the last packet. If you see an error, please contact NETGEAR Technical Support. 384 | Chapter 8. Commands for Status Monitoring and Statistics

Commands for Status Monitoring and Statistics

NETGEAR 8800 Chassis Switch CLI Manual

Usage Guidelines

This command enables sFlow on a particular list of ports. You also need to enable sFlow

globally in order to gather statistics and send the data to the collector. Once sFlow is enabled

globally, and on the ports of interest, sampling and polling begins.

Use the following command to enable sFlow globally:

enable sflow

Example

The following command enables sFlow sampling on the port 3:1:

enable sflow ports 3:1

enable sys-health-check

enable sys-health-check slot <slot>

Description

Enables backplane diagnostic packets on the specified slot.

Syntax Description

Default

Polling is enabled, backplane diagnostic packets are disabled.

Depending upon your platform, when you enable diagnostic packets, the system health

checker tests the data link every 5 seconds for the specified slot.

Usage Guidelines

Configure the system health checker with guidance from NETGEAR Technical Support

personnel.

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

packets. By isolating faults to a specific module or backplane connection, the system health

checker notifies you of a possible hardware failure.

System health check errors are reported to the syslog. Syslog output includes the slot

number where the problem occurred, the loopback packet ID number, and a notification that

the MSM/MM did not receive the last packet. If you see an error, please contact NETGEAR

Technical Support.

slot

Specifies the slot to participate in sending backplane diagnostic packets.
