SNMP configuration overview

Simple Network Management Protocol (SNMP) is an industry-standard protocol that enables you to use a standard SNMP management system to remotely manage network devices.

rSeries

systems support SNMPv1, SNMPv2c, and SNMPv3. You can configure the system from both the CLI and webUI.

SNMP software support

SNMP support is available in different ways, depending on which F5OS software version you are using. On F5 rSeries systems, SNMP is available from both the CLI and webUI.

F5 recommends using the newer

system snmp

commands, which include support for SNMP versions 1, 2c, and 3. For more information on the older commands, see:

F5 rSeries CLI Reference

F5 rSeries Planning Guide

F5OS-A software version	Older CLI (v1/v2c only)	Newer CLI (v1/v2c/v3)
1.2.0	SNMP-COMMUNITY-MIB SNMP-NOTIFICATION-MIB SNMP-TARGET-MIB SNMP-VIEW-BASED-ACM-MIB SNMPv2-MIB	system snmp communities system snmp engine-id system snmp targets system snmp users

Prerequisites for SNMP configuration

Before you configure SNMP access for F5 rSeries systems:

Add the SNMP manager IP address to the system allow list. For more information, see Configure the system allow list from the webUI.

Add descriptions to front-panel interfaces. For more information, see Configure an interface from the CLI.

Add descriptions to management interfaces. For more information, see Configure the management interface from the CLI.

Add descriptions to LAGs, if needed. For more information, see Configure a static LAG interface from the CLI.

Download the F5 MIB files from

File Utilities

in the webUI (on the left, click

SYSTEM SETTINGS

File Utilities

, and then from

Base Directory

, select

mibs

, select a

.tar.gz

file, and click

Download

Configure a DNS name server if you would like to use a fully-qualified domain name (FQDN) instead of an IP address for the SNMP trap destination. For more information, see Configure DNS from the webUI.

SNMP log overview

You can view SNMP information in the

/log/system/snmp.log

file. You can download the log file to your local workstation from the File Utilities screen in the webUI (on the left, click

SYSTEM SETTINGS

File Utilities

, and then from

Base Directory

, select

log/system

, select

snmp.log

, and click

Download

). For more information about managing files from the webUI or CLI, see File utilities overview.

SNMPWALK overview

SNMPWALK is an application on an SNMP management system that performs SNMP GETNEXT requests to query a network device for information. You can provide an object identifier (OID) to specify which portion of the object identifier space to search using GETNEXT requests. The SNMP management system queries all variables in the subtree below the specified OID, displays these values to the user, and stops when it returns results that are no longer inside the range of the specified OID.

These SNMP system object IDs (OIDs) are defined for each

rSeries

system type:

1.3.6.1.4.1.12276.1.3.1.1 (f5OsAppR5x00)

1.3.6.1.4.1.12276.1.3.1.2 (f5OsAppR10x00)

1.3.6.1.4.1.12276.1.3.1.3 (f5OsAppR2x00)

1.3.6.1.4.1.12276.1.3.1.4 (f5OsAppR4x00)

The IDs display in text format when the corresponding MIB is loaded in your SNMP management system. If the MIB is not loaded, the walk displays in OID format.

To more accurately map these system OIDs, you must download the F5-OS-SYSTEM-MIB.mib file and load it into your SNMP management system. To download the F5 MIB files, use File Utilities in the webUI (on the left, click

SYSTEM SETTINGS

System licensing overview

You can activate a license for the

rSeries

system from either the CLI or webUI. There is one license per

rSeries

system, which is also used by any tenants.

There are two ways to license the system:

Automatically: If your system is connected to the internet, use the Automatic method to prompt the system to contact the F5 license server and activate the license.
Manually: If your system is not connected to the internet, use a management workstation that is connected to the internet to retrieve an activation key from
F5
and then transfer it to the system.

Adding or reactivating a license on an active

rSeries

system might impact traffic on tenants. Traffic processing will stop briefly on the tenants, and then restart automatically. This occurs when the tenant receives a new or reactivated license causing a configuration reload on the tenants. For more information, see these other references:

System reboot overview

If you are having an issue with the system (such as unusually high CPU or memory usage or lockup), it is possible that rebooting might help to resolve the issue.

When there is a problem, the system sends alerts that you would see on the dashboard or on the Alarms & Events screen. You should rarely have to reboot the system, however, because typically if the system needs to reboot, it will do so automatically without administrator intervention. F5 recommends working with customer support if you think a system reboot is necessary.

Reboot the system from the CLI

You can manually reboot the system from the CLI.

Connect using SSH to the management IP address.

When you log in to the system, you are in user (operational) mode.

Reboot the system.

system reboot

In this example, you reboot the system:

appliance-1# system reboot
The reboot of the system results in data plane and management connectivity 
to be disrupted. Proceed? [no,yes]

It takes a few minutes for the system to reboot, and you will be logged out from the SSH session.

Reboot the system from the webUI

You can reboot the system from the webUI.

On the left, click

SYSTEM SETTINGS

General

Review the system status.

The

Reboot

button will not be available if the system is currently being rebooted.

If you decide that a reboot is necessary, in the System Operations & Status area, click

Reboot

A popup displays asking you to confirm the reboot operation.

It takes a few minutes for the system to reboot, and you will be logged out from the webUI.

OpenTelemetry Overview

OpenTelemetry streamlines observability in distributed systems through standardized APIs, libraries, and tools for collecting telemetry data, including traces, metrics, and logs.

F5OS OpenTelemetry enables the efficient collection of streaming metrics and logs in a structured format from the F5OS product to display in your observability platform. All the metrics and logs will be exported through a gRPC connection. The F5OS supports gRPC endpoints and each OpenTelemetry Line Protocol (OTLP) endpoint is provided with the ability to toggle instrument based filtering.

OpenTelemetry Metrics Overview

Telemetry subsystem within the F5OS platform layer generates common attributes and different metrics to display in your observability platform.

Instrument Overview

An instrument is an area of metrics, which contain multiple metrics and can be enabled selectively. F5OS Resource includes instruments.

Instument name	Description
platform	Standard platform stats such as memory, disk, CPU, and interface
tenant	Tenant-initiated stats such as memory, disk, CPU, and interface
optics	The front-panel optic DDM metrics
hardware	The low-level platform hardware sensors
container	Docker container stats for F5OS services
logs	Export the VELOS platform log file

Support for the intrument "tenant" is provided only for BIG-IP tenants.

This image provides a representation how the F5OS Resource includes instruments with multiple metrics:
