Appliance mode overview

You can run the system in
appliance mode
. Appliance mode adds a layer of security removing user access to Root and Bash. Enabling appliance mode disables all Root and Bash shell access for the system.
You can enable appliance mode at each of these levels:
  • System
  • Tenant
Appliance mode is disabled at all levels, by default. You can enable it from the webUI or the CLI. The appliance mode option for the system is available to users with admin access under
SYSTEM SETTINGS
General
in the webUI. For tenants, it is available in the webUI under
TENANT MANAGEMENT
Tenant Deployments
.
These are the effects of enabling appliance mode at each of the different levels.
System-level appliance mode
  • Root or Bash access is disabled on the system.
  • Console access: Root or Bash access is disabled on the system. Users can log in to the system CLI from the console using an admin account.
Tenant appliance mode
  • Root access to the tenant is disabled by all means. Bash access is disabled for users (with a terminal shell flag enabled) inside the tenant.
  • Users can access the tenant only through the webUI or the CLI.
  • Tenant console access: Users can log in to the CLI from the virtual console using an admin account (with a terminal shell flag enabled).

CLI idle timeout overview

For security purposes, you can configure how long management sessions can remain idle before you are logged out of the system. If you are connected using an SSH connection, the system closes the SSH connection after this time expires.

Configure the CLI timeout from the webUI

You can configure how long management sessions can remain idle before you are logged out of the system from the webUI. If you are connected using an SSH connection, the system closes the SSH connection after this time expires.
  1. Log in to the webUI using an account with admin access.
  2. On the left, click
    SYSTEM SETTINGS
    System Security
    .
  3. In the Services area, for
    CLI Idle Timeout
    , enter a time, in seconds, for how long management sessions can remain idle before they time out.
    A value of 0 (zero) sets the time to infinity, so the user is never logged out. The timeout can be a value from 0 through 8192 seconds. The default value is 1800 seconds (30 minutes).
  4. Click
    Save
    .

Configure system idle timeout from the CLI

You can configure how long management sessions can remain idle before you are logged out of the system from the CLI. If you are connected using an SSH connection, the system closes the SSH connection after this time expires. You can also configure how long the system is inactive for a root user connected to the system or via SSH or console before the user is logged out of the system.
  1. Log in to the command line interface (CLI) of the system using an account with admin access.
    When you log in to the system, you are in user (operational) mode.
  2. Change to config mode.
    config
    The CLI prompt changes to include
    (config)
    .
  3. Configure the CLI session idle timeout setting for an admin user connected to the system.
    system settings config idle-timeout <
    time-in-seconds
    >
    A value of 0 (zero) sets the time to infinity, so the user is never logged out. The timeout can be a value from 0 through 8192 seconds. The default value is 1800 seconds (30 minutes).
    This example sets an idle timeout of 3600 seconds (one hour):
    appliance-1(config)# system settings config idle-timeout 3600
  4. Configure the CLI session idle timeout setting for an admin or a root user connected via either SSH or console.
    system settings config sshd-idle-timeout <
    time-in-seconds
    >
    A value of 0 (zero) sets the time to infinity, so the user is never logged out. The timeout can be a value from 0 through 8192 seconds. The default value is 0 (zero).
    This example sets an SSH system idle timeout of 3600 seconds (one hour):
    appliance-1(config)# system settings config sshd-idle-timeout 3600

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.
F5
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:
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:

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
F5
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
File Utilities
, and then from
Base Directory
, select
mibs
, select a
.tar.gz
file, and click
Download
).

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:

OpenTelemetry configuration from the CLI

Display instruments from the CLI

An instrument is an area of metrics, which contain multiple metrics and can be enabled selectively.
Before configuring an exporter, you can display supported instruments from the CLI.
  1. Connect using SSH to the management IP address.
  2. Log in to the command line interface (CLI) of the system using an account with admin access.
    When you log in to the system, you are in user (operational) mode.
  3. Show the total and available instruments:
    show system telemetry instruments
    This example displays the available instruments:
    appliance-1# show system telemetry instruments NAME DESCRIPTION ------------------------------------------------------------------------------------- all Report all logs and metrics produced by the F5OS platform layer logs F5OS platform log file through the OpenTelemetry 'log' API platform F5OS platform metrics such as: memory, disk, cpu, interface stats hardware F5OS hardware sensors such as: voltage, current, temperature, power, fan-speeds optics F5OS front-panel Optic DDM metrics tenant Low level tenant reported metrics such as: memory, disk, cpu interface stats container F5os Per-Container metrics such as: cpu, block-io, network, memory

Configure an exporter from the CLI

An exporter defines an OpenTelemetry gRPC endpoint to which the F5OS Platform will push metrics/logs.
You can configure the exporter from the CLI.
  1. Connect using SSH to the management IP address.
  2. Log in to the command line interface (CLI) of the system using an account with admin access.
    When you log in to the system, you are in user (operational) mode.
  3. Change to config mode.
    config
    The CLI prompt changes to include
    (config)
    .
  4. Configure the exporter.
    You must specify the IPv4 address or DNS name of the server and the port number of the server on which OpenTelemetry (OTEL) is running
    system telemetry exporters exporter <
    server name
    > config endpoint address <
    address
    > port <
    port number
    > instruments <
    instrument name
