UCView Simple Network Management Protocol (SNMP) Integration.
It’s no secret that managing digital signage networks and applications are complex tasks. Multiple Technologies are in use today, often by the same organization. This article presents an overview of one technology: the UCView SNMP (Simple Network Management Protocol). UCView SNMP offers a method to monitor and manage digital signage player. This Document offers a simplified view of UCView SNMP fundamentals and explains how the Fundamental components work together. Prior to UCView SNMP, users can only control the functionality of their players and ads through the online content management system. Using UCView SNMP allow you to control some functionality of the player like activating interactive ads place text on the screen, close and open the screen etc. Implementation Now that we’ve looked at definitions, it’s easier to see how UCView SNMP operates in a network. In its simplest form, UCView SNMP agent is loaded on a player with the Appropriate command components. command components include. The player is configured to communicate with one or more NMS using specific UCView SNMP community strings. The NMS IP address is also configured to enable the players to send Notifications. The Player contains the UCView SNMP commands. The NMS is configured with the same community strings as the player it manages. The players is also configured with the appropriate combination of the UCView SNMP Commands, username, and password that’s required to manage the player for which it is responsible. The NMS is also configured, either manually or through automatic discovery, with the IP addresses of the players it is to manage. Note that SNMP communication requires network player to open UDP Ports 161 and 162 for polling and Traps/commands
Configuring UCView SNMP Access The UCView SNMP helper, require SNMP or Telnet access to devices in order to perform their function. This section describes how to configure inserts into the device access databases. Any Precision IP components that require SNMP or Telnet access use the settings from these databases. In this section, the UCView SNMP helpers are used as representative examples of these processes.
UCView SNMP helpers that require SNMP access use two SNMP user access and password configuration files to gain access to player on the network: Synopsis
snmpcommand [-V] [-O] [-C] [-R] [-T] [-A] [-i ad_id] [-I Textmesg] [-P PARSEROPTS] [-m mibs] [-M mibdirs] [-d] [-D TOKEN[,TOKEN,...]]
[-H Horizontal_pixels] [-V Vertical_pixels] [-b boxsize] [-u username] [-p password] [-H Horizontal_pixels] [-V Vertical_pixels] [-b boxsize] [-u username] [-p password]
Description
The following are the common arguments for UCView SNMP commands. Applications may provide
additional parameters (commandparams) that are specified after the player and authentication
controls specified here.
| -V | Prints the version string for the application. |
| -C | Turn off player command. |
| O | Turn on player command. |
| -i AdID | Activate immediate ad on the player. |
| -R | Specifies command to Restart player. |
| -T | context Sets the content context used for UCView SNMPv3 messages. Default contextName is the empty string “”. |
| -A | Alert Activate Alert on screen (Combine with alert Text message) |
| -H Horizontal | Specifies horizontal pixel location |
| -V Vertical | Specifies vertical pixel location |
| -B Boxsize | Specifies pixel text box size. |
| -u username | Sets the user name used for authenticated UCView SNMP |
| -p authpasswd | Sets the authentication pass phrase used for authenticated UCView SNMP. |
Conclusion
Through the use of UCView SNMP players, information technology digital signage
has grown dramatically and has drastically reduced the requirement for administrators to
manually monitor individual player’s components. The ability to have systems informs an
NMS, control playlist and operation of digital signage players. While not perfect,
SNMP provides many of the tools necessary to control player within local network, to display
alert activate ads and announce messages on the screen and more.
