High Availability (HA) configuration overview
You can configure system controller high availability (HA)
from Controller Management screen on the system controller webUI. The system controllers work together as a
redundant pair. The default mode for system controller HA is Auto, which
automatically selects the system controller that is best suited at the time as
the active controller and fails over only as needed.
The High Availability screen on the chassis partition webUI includes options
for configuring chassis partition HA. High availability is already implemented for
chassis partitions on the
VELOS
system.
Configure high availability for the system controllers
from the webUI
You should not need to change system
controller high availability (HA) to something other than the default
configuration (Auto), but you can opt to change the configuration or initiate
a failover from the active controller to the standby from the system
controller webUI.
Log in to the VELOS system controller
webUI using an account with admin access.
On the left, click
SYSTEM
SETTINGS
Controller
Management
.
For the
Preferred Node
field, select
System
Controller 1
or
System Controller 2
to act as an active system controller, or choose
Auto
(recommended).
Changing the Preferred Node
configuration creates a failover event and ends the session if you
select the system controller that is currently acting as the
standby. Wait 30 seconds and then start a new session with either
the floating IP address or the active system controller IP address
after the change has completed.
Hardware health conditions of
the system controllers always take precedence. If one of the system
controllers is not healthy, the chassis partition will ignore the
preference and synchronize with the healthy system controller.
To force a failover to occur
immediately, click
Failover
.
The
Failover
button
is available only when
Preferred Node
field is set to

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.

options for configuring remote log servers and the log severity level
for individual software components and services.
From the
webUIs
you can generate a system report,
or QKView file, to collect configuration and diagnostic information from the
VELOS
system if you have any concerns about
your system operation. The QKView file contains machine-readable (JSON) diagnostic data
and combines the data into a single compressed tar.gz format file. You can upload the
QKView file to F5 iHealth where you can get help to
verify proper operation of the system and get help with troubleshooting and
understanding any issues you might be having and ensure that the system is operating at
its maximum efficiency.
You can view event logs and configure secure remote logging from the CLI.
You can also send host log files, which are in the
/var/log
directory, as well as
audit.log files to the remote server from the CLI.

Time settings overview
You can configure Network Time Protocol (NTP) for the
VELOS
system. An NTP server ensures that the
system clock is synchronized with Coordinated Universal Time (UTC). The system also
provides authentication support for NTP, which can enhance security by ensuring that the
system sends time-of-day requests only to trusted NTP servers. You can also configure
the time zone and set the time and date manually, if NTP is disabled. You can use either
the
system controller
CLI or webUI to configure time
settings.
Configure time settings from the webUI
After the
VELOS
system license is activated, you can configure
Network Time Protocol (NTP) servers, including authentication support for NTP,
time zone, and manual configuration of date and time, if NTP is disabled. The
NTP server ensures that the system clock is synchronized with Coordinated
Universal Time (UTC). You can specify a list of servers that you want the
system to use when updating the time on network systems. You can configure
time settings for the system from the system controller webUI.

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.
VELOS
systems support SNMPv1,
SNMPv2c, and SNMPv3. You can configure the system from both the CLI and
webUI.
You can use SNMP to monitor VELOS systems at
both the system controller and chassis partition levels. For more
comprehensive monitoring, configure your system at both levels from the CLI or
webUI. SNMP traps always send from the active system controller’s fixed
management IP address as the source IP address.
SNMP software support
SNMP support is available in different ways,
depending on which F5OS software version you are using. On VELOS
systems, SNMP is available from both the system controller and chassis
partition CLIs and webUIs.
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:
in the system
controller or chassis partition 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 or Configure DNS from the CLI.
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 system controller or chassis partition 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 system
controller or chassis partition 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.
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
system controller or chassis partition
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
VELOS
system from either the system
controller CLI or webUI. There is one license per
VELOS
system, which is used by the chassis partitions and
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
VELOS
system might impact traffic on tenants
running on chassis
partitions
. 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:
The system is now licensed. If a base
registration key or add-on key fails to activate, try re-activating the
license or contact support.f5.com.
View the license from the webUI
You can view information about the
software license activated on your system, including license activation and
expiration dates, service check date, and licensed modules, from either the
system controller or chassis partition webUIs.
Log in to the VELOS system controller
webUI or the chassis partition webUI using an account with admin
access.
On the left, click
SYSTEM
SETTINGS
Licensing
.
View the license information for the
system.
System licensing from the CLI
License the system automatically from the CLI
For automatic
VELOS
system licensing,
the system needs to be able to connect to the F5 licensing server either
through the internet or another means of networking. You need to have the Base
Registration Key (five sets of characters separated by hyphens) provided by
F5, and any add-on keys (two sets of 7 characters separated by a hyphen) that
you have purchased. The Base Registration Key with associated add-on keys are
pre-installed on a new
VELOS
system.
You can activate the
VELOS
system license automatically
from the system controller CLI.
Connect using SSH to the system
controller floating management IP address.
Log in to the command line interface
(CLI) of the system controller using an account with admin
access.

If you are having an issue with a chassis partition (such as unusually high CPU or
memory usage or lockup), it is possible that rebooting a blade in the chassis partition 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. A blade status of
Not ready
for a prolonged time on the
General screen can also indicate the need to reboot the blade. You should rarely have to
reboot a blade, however, because typically if the
VELOS
system needs to reboot a blade, it will do so automatically
without administrator intervention. F5 recommends working with customer support if you
think a blade reboot is necessary.
