Configuring AAA
Authentication determines who the user is and whether that user should be allowed access to the network
or a particular device. It allows network administrators to bar intruders from their networks. It may use
a simple database of users and passwords. It can also use one-time passwords.
Authorization determines what the user is allowed to do. It allows network managers to limit which
network services are available to different users.
Accounting tracks what users did and when they did it. It can be used for an audit trail or for billing for
connection time or resources used (bytes transferred).
Collectively, authentication, authorization, and accounting are sometimes referred to as AAA. Central
management of AAA means the information is in a single, centralized, secure database, which is much
easier to administer than information distributed across numerous devices.
In the VDS-OS network, login authentication and authorization are used to control user access and
configuration rights to the SEs, SRs, and VOSM. There are two levels of login authentication and
authorization:
•
Device
•
VOSM
In a VDS-OS network, user accounts can be created for access to the VOSM and, independently, for
access to the SEs and SRs that are registered to the VOSM.

Configuring AAA
This section covers login authentication and authorization for the VOSM. For information about device
login authentication and authorization, see the “Login Access Control” section on page 1-19 and the
“Authentication” section on page 1-27.
Login authentication is the process by which VOSM verifies whether the person who is attempting to
log in has a valid username and password. The person logging in must have a user account registered
with the device. User account information serves to authorize the user for login and configuration
privileges. The user account information is stored in the AAA database. When the user attempts to log
in, the VOSM compares the person’s username, password, and privilege level to the user account
information that is stored in the database.
Each user account can be assigned to a role and a domain. A role defines which VOSM configuration
pages the user can access and which services the user has authority to configure or modify. A domain
defines which entities in the network the user can access and configure or modify. You can assign a user
account to zero or more roles, and to zero or more domains.
Creating, Editing, and Deleting Users
Note
This section is addressed to users with administrator-level privileges (admin users) only.
Two default user accounts are preconfigured in the VOSM. The first account, called admin, is assigned
the administrator role that allows access to all services and access to all entities in the system. This
account cannot be deleted from the system, but it can be modified. Only the username and the role for
this account are unchangeable. To change the password for this account, use the username admin
password password command through the CLI.
The second preconfigured user account is called default. Any user account that is authenticated but has
not been registered in the VOSM gets the access rights (role and domains) assigned to the default
account. This account is configurable, but it cannot be deleted nor can its username be changed.
When you create a new user account in the VOSM, you have the option to create the user account in the
CLI for the VOSM device at the same time. Using this option to create the new account in the CLI
provides the following benefits:
•
User account is created in the primary and standby VOSM management databases and in the VOSM
CLI from one central point.
•
Users can change their passwords, and the password changes are propagated to a standby VOSM.
If you choose to create the user account from the VOSM without creating the user account in the VOSM
CLI at the same time, the following results apply:
•
User account is created in the primary and standby VOSM management databases.
•
No user account is created in the VOSM CLI, and the user cannot log in to the VOSM until an
account is created from the CLI.
•
Local users cannot change their passwords using the VOSM.
•
Local users can change their passwords using the CLI; however, the password changes are not
propagated from the CLI to the VOSM databases when the CLI user option is enabled in the VOSM.
If a user account has been created from the CLI only, when you log in to the VOSM for the first time,
the Centralized Management System (CMS) database automatically creates a user account (with the
same username as configured in the CLI) with default authorization and access control. However, to
change the password in this scenario, the user account must be explicitly configured from the VOSM
with the CLI user option enabled.

User accounts created in the VOSM should always be deleted from within the VOSM.
Creating, Editing, and Deleting Roles
Although the VOSM provides many types of services, not all users have access to all services. Users are
assigned a role, which indicates the services to which they have access. A role is a set of enabled
services.
Each user account can be assigned zero or more roles. Roles are not inherited or embedded. The VOSM
provides one predefined role, known as the admin role. The admin role has access to all services and all
VDS-OS network entities.
Note
The admin user account, by default, is assigned to the role that allows access to all domains and all
entities in the system. It is not possible to change the role for this user account.

Creating, Editing, and Deleting Domains
A domain is a set of VDS-OS network entities or objects that make up the VDS-OS network. Whereas
a role defines which services a user can perform in the VDS-OS network, a domain defines the entities
to which the user has access. An entity can be a Service Engine, a device group, or an origin service.
These predefined entities are treated like services and can be enabled or disabled when you set up user
roles.
When you configure a domain, you can choose to include Service Engines, device groups, or origin
services in the domain.

Changing a Password
If you are a user without admin privileges and you are logged in to the VOSM, you can change your own
VOSM and CLI user password if you meet the following requirements:
Caution
•
Your CLI user account and password were created in the VOSM and not in the CLI.
•
You are authorized to access the Password page.
We do not recommend changing the CLI user password from the CLI. Any changes to CLI user
passwords from the CLI are not updated in the management database and are not propagated to the
standby VOSM. Therefore, passwords in the management database do not match a new password
configured in the CLI.
The advantage of initially setting passwords from the VOSM is that both the primary and the standby
VOSMs are synchronized, and VOSM users do not have to access the CLI to change their passwords.
To change the VOSM and CLI user password for the user account that is currently logged in to the
VOSM, do the following:
Step 1
Choose System > Password. The Password page is displayed.
Step 2
In the New Password field, enter the changed password.

Configuring Device Offline Detection
Communication between all devices and the VOSM use User Datagram Protocol (UDP), which allows
for fast detection of devices that have gone offline. UDP heartbeat packets are sent at a specified interval
from each SE to the primary VOSM in a VDS-OS network. The primary VOSM tracks the last time it
received a UDP heartbeat packet from each SE. If the VOSM has not received the specified number of
UDP packets, it displays the status of the nonresponsive SEs as offline.
Note
In VDS-OS networks with heavy traffic, dropped UDP packets can cause the VOSM to incorrectly report
the status of SEs as offline. To avoid this problem, configure a higher value for dropped UDP heartbeat
packets.
To configure Device Offline Detection, do the following:
Step 1
Choose System > Configuration > Device Offline Detection. The Configure Device Offline Detection
page is displayed.
Note
The Device Offline Detection feature is in effect only when the VOSM receives the first UDP
heartbeat packet from an SE. UDP port of the heartbeat on the VOSM must be reachable for all
devices; otherwise, the device shows as offline.

Step 2
In the Heartbeat Rate field, specify how often, in seconds, the SEs should transmit a UDP heartbeat
packet to the VOSM. The default is 10. The range is from 5 to 3600.
Step 3
In the Heartbeat Fail Count field, specify the number of UDP heartbeat packets that can be dropped
during transmission from SEs to the VOSM before an SE is declared offline. The default is 3. The range
is from 1 to 100.
Note
Step 4
Decreasing the heartbeat interval (Heartbeat Rate * Heartbeat Fail Count) may take twice the
original configured time to take effect. During this time, the online device status is not changed
to “Offline” or “Online [Waiting for datafeed].”
In the Heartbeat UDP Port field, specify the VOSM port number that the SEs use to send UDP heartbeat
packets. The default is 2000. The range is from 1000 to 10000.

Configuring Global Routing
Coverage Zone File Registration
See Appendix 1, “Creating Coverage Zone Files,” for information about creating a Coverage Zone file.
The system administrator places a Coverage Zone file where the VOSM or individual devices can access
the URL. The administrator then registers the Coverage Zone file URL in the VOSM. Coverage Zone
files can be applied globally to the entire VDS-OS network, or locally to a specific SR. If a Coverage
Zone file is made global, then it is read and parsed by each SR that does not have a Coverage Zone file
assigned. If the coverage zone is specified in an individual SR configuration, it is only applied to that
particular SR.
You have the choice of using two types of coverage zones:
•
Default coverage zones
•
User-defined coverage zones
A default coverage zone consists of all the SEs that reside in the same local network segment, or subnet.
The VOSM provides a check box to specify whether the default coverage zone is to be used.
A user-defined coverage zone consists of all the SEs that are specified in a Coverage Zone file. This file
defines the network segments to be covered in the routing process. The Coverage Zone file is registered
with the VOSM and then applied to an SR for routing definitions.

file to use for that purpose.
The following XML schema files are available:
•
VOSCoverageZone.xsd—Coverage Zone file is used to customize the networks and geographic
regions each SE services.
VDS-OS uses the VOSCoverageZone.xsd XML schema file to customize the networks and
geographic regions that are serviced by each SE.
•
VOSCaptureSchedule.xsd—Capture Schedule file used to convert live content to VOD content
(such as catch-up-to-live and start over)
To open or save an XML schema file, do the following:
Step 1
Choose System > Files > XML Schema Files. The VOS-IS XML Schema page is displayed with a link
to each XSD (schema) file.
Step 2
