Allowed SSL cipher suites for httpd service

When you configure ciphers for httpd, you can use multiple formats. You can specify a single cipher suite, such as RC4-SHA. You can also represent a list of cipher suites containing a certain algorithm or cipher suites of a certain type using a shortened name. For example, SHA1 represents all cipher suites using the digest algorithm SHA1, and SSLv3 represents all SSLv3 algorithms. You can combine lists of cipher suites into a single cipher string using the + character as a logical AND operation. For example, SHA1+DES represents all cipher suites containing the SHA1 and DES algorithms.

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 an 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 management IP addresses 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

File Utilities

Certificate management overview

Before

rSeries

systems can exchange data with one another, they must exchange device certificates, that is, digital certificates and keys used for secure communication.

If you are using LDAP with transport layer security (TLS) for user authentication, you can choose to require TLS Certificate Validation in the authentication settings. You can add a certificate and key into the system, and when you create a certificate signing request (CSR), it saves the generated key and certificate to these directories:

system/aaa/tls/config/key

system/aaa/tls/config/certificate

When you install an SSL certificate, you also install a certificate authority (CA) bundle, which is a file that contains root and intermediate certificates. The CA bundle and server certificate complete the SSL chain of trust.

You can also configure a Certificate Revocation List (CRL) entry for the system to use to check revocation status of a certificate prior to authenticating a client. Note that once you have configured a CRL, there must be a CRL certificate for each CA. If there are two CAs configured and one CRL is been added for one of the CAs, you need to provide a CRL for the other CA even if it is not revoked.

As an alternative to CRLs, you can also use Online Certificate Status Protocol (OCSP). You can configure the system to use both at the same time. For more information about OCSP, see OCSP configuration overview.

Client certificate authentication overview

For enhanced security, users with admin access can configure the system so that webUI users use a client certificate to provide a username and authenticate before granting access to the

rSeries

system. The system verifies a user's identity by validating the client certificate against a list of trusted Certificate Authority (CA) certificates, and optionally checks the certificate status against a configured Certificate Revocation List (CRL) or Online Certificate Status Protocol (OCSP) responder. The system extracts the user name from the certificate and uses it to query an external server for group membership information for the user, which is used to determine what features they can access on the system. You can also configure client certificate authentication to work with an LDAP authentication provider.

Configure client certificate verification from the webUI

You can enable verification of httpd client certificates from the webUI.

On the left, click

SYSTEM SETTINGS

Certificate Management

In the Client Certificate Verification area, click

Settings

The Client Certificate Verification screen displays.

For

Verify Client

, select whether to enable client certificate verification.

The default value is false (verification is disabled).

For

Client Depth

, select the client certificate verification depth.

The default value is 1, which indicates that the client certificate can be self-signed or must be signed by a Certificate Authority (CA) that is known to the server. A depth of 0 indicates that only self-signed client certificates are accepted. The range is from 0 to 100. The value you provide for depth indicates the maximum number of CA certificates allowed to be followed while verifying the client certificate. You might need to raise the default depth if you received more than one chained root certificate in addition to a client certificate from your CA.

Log in to the system webUI using a client certificate

Before you can log in to the webUI using client certificate authentication, you must import the certificate to your browser. This procedure varies depending on operating system and browser.

You can log in to the system webUI using a client certificate for authentication.

Connect to the webUI by entering the management IP address in your browser.

On the login screen, review the client certificate authentication agreement, if available, and then click

When prompted to select a certificate, select the certificate from the list and click

When authentication completes, the Dashboard displays. If you did not import a certificate to your browser, the authentication fails and displays an error message.

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:

F5 rSeries Systems: Installation and Upgrade

at Documentation - F5OS-A and F5 rSeries

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:
