User Guide

iControl SNMP management functions are implemented by SNMP drivers. Once installed and
configured, they allow iControl to communicate with the corresponding SNMP agents
running on the devices being monitored. For example, if you install the driver for an
integrated receiver/decoder (IRD), and then enable the SNMP agent on the IRD itself, iControl
will be able to get status information on the device by polling or querying the IRD’s agent, and
to issue controls (such as restart), if they are supported.
A generic SNMP manager is also available that allows you to write your own SNMP drivers.
iControl SNMP Agents
iControl SNMP agents allow third party SNMP managers, such as Spectrum, to monitor an
iControl configuration.
There are two types of iControl SNMP agents:
• the GSM SNMP Agent, which is an iControl plug-in
• the Net-SNMP agent, part of a popular open-source package (www.net-snmp.org)
GSM SNMP Agent
The GSM SNMP agent is an iControl plug-in that allows reporting statuses and alarms for all
managed devices over SNMP. It reports the status and alarms of cards in the form of an SNMP
table that can be queried or polled by a third party SNMP manager. The GSM SNMP agent also
enables iControl to send traps to a third party SNMP manager.
Note: The generic SNMP manager and third party SNMP drivers are not included in
the basic iControl package. They must be purchased separately. Contact your Grass
Valley sales representative for details.
IMPORTANT: If you choose to take advantage of iControl’s support for the SNMP version 3
protocol for its added security, and your Application Server is an SNMP agent,
you must first create default user templates and then create user profiles with
the desired privilege levels. For more information, see
"Preparing an Application
Server (as SNMP Agent) to use SNMPv3" , on page 380.
