Engineering Access Level Pages
This appendix describes the VVIM or CDSM pages available through the Engineering access level. The Engineering access level provides the following pages:
•CDSM or VVIM Diagnostics
•CDSM or VVIM Setup
The Engineering access level is primarily used for initializing the CDS at the time of installation and for system diagnostics. Once your system has been configured, you should not require an engineering access level user for day-to-day operations.
When you log in to the CDSM with a user account that has Engineering access level, the first page that is displayed is the CDSM Setup page. All the other CDSM pages that are available with the Master access level are still available with the Engineering access level.
In an RTSP environment, the Configure > Server Level > RTSP Setup page displays four additional fields:
•Database Connect Size
•UDP Packet Size
These fields are only for diagnostic purposes, and their values should not be changed.
Note When you configure the CDSM for Virtual Video Infrastructure (VVI), all references to CDSM are changed to Virtual Video Infrastructure Manager (VVIM) for the Vault and Caching Node manager. For example, the CDSM Audit Logs available through the Report > System Level left-panel menu is changed to the VVIM Audit Logs when VVI is configured on the CDSM Setup page, which changes to the VVIM Setup page.
CDSM or VVIM Diagnostics
To access the CDSM or VVIM Diagnostics page, choose Maintain > Software > CDSM Diagnostics or VVIM Diagnostics. The first section of this page provides configuration information that is useful in diagnosing a problem. The following remaining sections of the CDSM or VVIM Diagnostic page are:
•Stream Trickmode Debugger
•Unix Timestamp Tool
By entering an IP address and network mask, and clicking Submit, the Classless Inter-Domain Routing (CIDR) Calculator provides the following TCP/IP network information:
•Number of hosts
•Range of IP addresses for the hosts
Stream Trick-Mode Debugger
To view the trick-mode data for a Session ID enter the Session ID and click Submit. The CDSM or VVIM Diagnostic page refreshes and a View Data button is displayed next to the Submit button. Click View Data to see the raw trick-mode data. A new window displays the data. Right-click in that window and choose View Source in the pop-up menu. A formatted version of the raw data is displayed.
Unix Timestamp Tool
Clicking on a day in the calendar displays the Unix start time and end time. The time is represented in seconds since the start of Unix epoch time, which is 1970-01-01T00:00:00.
Choose a server from the Server Diagrams drop-down list and a graphic of the server is displayed.
CDSM or VVIM Setup
The CDSM or VVIM Setup page is used to initially configure the CDS. After you have set the CDSM or VVIM Setup fields for your system, click Submit. Configuration and start up messages are displayed in the left panel.
Deployed CServer Version
For Release 2.1, this field is always set to 2.1.x.
Stream Failover Support
Stream failover support is available for both the ISA and RTSP environments. If a Streamer fails, another Streamer in the same Stream Group takes over any active stream sessions without loss of state and backoffice independence.
Stream Steering Mode
Stream steering determines which Streamers serve streams to a QAM device. There are two types of stream steering:
•Single site (Silo site steering)
Single-site steering uses only one Stream Group to serve streams to all QAM devices. Multi-site steering can use more than one Stream Group to serve streams to the QAM devices. The QAM Gateway page reflects whether single-site or multi-site steering is enabled, by the number of preference levels available. Multi-site steering offers four preference levels (high, medium, low, and none). Single-site steering offers two preference levels (high and none).
Note Multi-site steering is only available with ASI streaming in an ISA environment.
Deployment Network Config
Specify whether your CDS network topology is a Layer 2 or Layer 3 network.
The only options for Release 2.1 are ISA 2.1 and RTSP 2.1.
The possible settings for Stream Destination are Cable and IPTV.
The cable setting is the existing configuration with the QAM Gateway page and Headend Setup page, which allows you to map Stream Groups to QAM devices and service groups if applicable.
The IPTV setting provides the Stream Destination page in place of the QAM Gateway page and Headend Setup page. The Stream Destination page allows you to map the Stream Groups to specified subnets, which is useful in IPTV networks where each end-user has an IP address.
An option for ISA environments using the IPTV setting for the Stream Destination is the NAT option. The NAT Traversal feature allows streaming to client devices that are behind a NAT device.
Note The Stream Destination feature is only available for single-site steering.
When Vault Redundancy is enabled and at least two Vault Groups are configured and mapped to each other, at least one copy of each content within a group is mirrored to the configured peer group. The Vault Redundancy adds the Vault Groups and Vault Redundancy Mapping configuration pages to the Array Level.
Note In Release 2.1, the maximum number of Vault Groups is two.
This feature is not activated in this release.
Thin Pipe Management
Thin Pipe Management allows you to configure low-bandwidth connections between local and remote groups. A local group consists of servers in the same group (Stream Group, Cache Group, Vault Group). A remote group consists of servers in other Stream Groups, Cache Groups, and Vault Groups. Use the Thin Pipe Map page to configure this feature.
Shared Content Store
Shared Content Store is an optional feature for the ISA environment. The Shared Content Store allows one instance of a Content Store to be shared with many instances of Stream Services, each located in its own video hub office (VHO) with its own video backoffice (VBO).
Virtual Video Infrastructure
The Virtual Video Infrastructure (VVI) provides management of the Caching Nodes in a central management configuration or a split-domain management configuration.
When you enable VVI, you need to choose the Management System Role of the CDSM. The Management System Role has the following options:
•VVI and Stream Manager—Central management of all Vaults, Caching Nodes, and Streamers
•VVI (Vault/Cache) Manager—Management of only the Vaults and Caching Nodes
•Stream Manager—Management of only the Streamers
The Cache Fill Protocol options are for selecting the type of data communication that is used between Caching Nodes and Streamers. Cache Control Protocol (CCP) is used for communication among the Vaults, Caching Nodes, and Streamers. If you are using HTTP to communicate between the Caching Nodes and Streamers, please content Cisco Technical Support for instructions on enabling it. For more information about CCP Streamers and HTTP Streamers, see the "Caching Node Workflow" section on page 2-9.
Note HTTP Streamers are supported in an ISA environment and an RTSP environment. However, HTTP Streamers are not supported in an ISA environment using the Shared Content Store feature.
The split-domain management is made up of the VVI (Vault/Cache) Manager and the Stream Manager. In order for the Stream Manager to be able to communicate with the VVI Manager, you need to enter the IP address of the VVI Manager in the VVI (Vault/Cache) Manager VVIM IP field.
If you choose CCP as the cache-fill protocol, you also need to provide a name for the Stream Manager in the Stream Domain Name field. Communication between the VVI Manager and the Stream Manager uses port 80. If port 80 is not open for communication, you can enter the data manually, or upload an XML file, depending on the information required. All pages requiring communication to the VVI Manager offer both an import (over port 80) and an upload option (XML file), or manual configuration.
Note When you configure the CDSM for Virtual Video Infrastructure (VVI), all references to CDSM are changed to Virtual Video Infrastructure Manager (VVIM) for the Vault and Caching Node manager.
The VVIM and Stream Managers display different configuration, monitoring, reports, and maintenance pages based on the servers they manage. For example, when CCP is the cache-fill protocol, the VVIM displays the Configuration Generator page in the Maintenance > Software left-panel menu. The Configuration Generator page is used to generate the group IDs and server IDs for the Stream Managers to use in their domains.
Configuring Split-Domain Management
To configure a VVIM that uses split-domain management, set the VVI fields as follows:
•Management System Role—VVI (Vault/Cache) Manager
•Cache Fill Protocol—HTTP
Note Shared Content Store must be enabled in order to use VVI.
To configure a Stream Manager that uses split-domain management, set the VVI fields as follows:
•Management System Role—Stream Manager
•Cache Fill Protocol—HTTP
•VVI (Vault/Cache) Manager VVIM IP—IP address of the VVIM
•Stream Domain Name—Domain name for the Stream Domain
The Media Scheduler is an optional feature and requires a software activation key to enable it. For more information about activating the Media Scheduler, see the "Initializing the CDS and Activating the Optional Features" section on page 3-3. The Media Scheduler allows live ingests from multicast IP addresses and uses the Input Channels page to map multicast IP addresses to channels. You can enable either Media Scheduler or Real-Time Capture Type, but not both.
Real-Time Capture Type
Real-Time Capture allows live ingests from multicast IP addresses and uses the CallSign Setup page to map the multicast IP addresses to call signs. You can enable either Media Scheduler or Real-Time Capture Type, but not both.
The Bandwidth Manager is an optional feature and is only for RTSP environments. The Bandwidth Manager keeps track of allocated streams and VOD network resources.
The Ingest Manager is an optional feature and requires a software activation key to enable it. For more information about activating the Ingest Manager, see "Initializing the CDS and Activating the Optional Features" section on page 3-3. The Ingest Manager takes care of provisioned content objects by collecting the metadata, sending messages to the appropriate subsystem to ingest the content, and sending messages to expire the content when the expiration period has passed.
RTSP Deployment Type
The RTSP Deployment type is only applicable to RTSP environments. The options are the following:
•EventIS (on vpath and off vpath)
The deployment configuration differs depending on the type of headend.
The Authentication Manager is an optional feature and is only for specific RTSP environments (EventIS or Telenet). The Authentication Manager communicates with the backoffice to validate a request received from a set-top box before setting up a session.
Service Group Steering
Service Group Steering is an optional feature and is only for RTSP environments. When the Service Group Steering option is turned on, the Configure > System Level > Headend Setup page is available to steer Stream Groups to specific service groups.
CDSM or VVIM NAV Setup
The CDSM NAV Setup changes what displays in the CDSM GUI.
CDSM or VVIM Health Monitoring
The CDSM Health Monitoring is not supported in Release 2.0.
The System Configs page contains critical CDS parameters that are set at the time of the initial installation of the CDS. Generally, the default settings are appropriate for all environments.
If these parameters are changed once the CDS is in service, your CDS may not function properly.
Group Map 0
Specifies whether the Group Map 0 parameter is for an ISA or RTSP environment.
Servers Group Map
Specifies whether the Servers Map 0 parameter is for an ISA or RTSP environment.
This is the CDS license, and is set at the time of installation.
Control IP Map
The Control IP Map is always set to one.
Add New Server
Should you experience problems adding a new server into the CDS, and you have tried the solutions covered in the "CDSM GUI Does Not Register the Vaults and Streamers" section on page A-22, you can use the Add New Server section.
