SnmpNetwork
SnmpNetwork represents a network of manageable Snmp devices. Can also be configured to handle sending and receiving Snmp
trap messages, as well as respond to Snmp requests from outside managers. The SnmpNetwork is available in the nSnmp module.

In addition to the standard properties (Status, Enabled and Fault Cause), these properties are unique to this component.
| Property | Value | Description |
|---|---|---|
| Health | read-only | Reports the status of the network, device or component. This advisory information, including a time stamp, can help you recognize and troubleshoot problems but it provides no direct management controls. |
| Alarm Source Info | additional properties | Contains a set of properties for configuring and routing alarms when this component is the alarm source. |
| Monitor | additional properties | Configures a network's ping mechanism, which verifies network health. This includes verifying the health of all connected objects (typically, devices) by pinging each device at a repeated interval. |
| Tuning Policies | additional properties |
Selects a network tuning policy by name. This policy defines stale time and minimum and maximum update times. During polling, the system uses the tuning policy to evaluate both write requests and the acceptability (freshness) of read requests. |
| Poll Scheduler | additional properties | Configures the frequency with which the driver polls points and devices. |
| Enterprise | numeric | Configures the enterprise OID (Object Identifier)1.3.6.1.4.1.4131 information for the station. |
| Contact | text | Configures the system contact information for the station. This contact information is stored for the station and is read/write accessible via Snmp requests made to the station for OID 1.3.6.1.2.1.1.4.0. |
| System Name | text | Configures the system name information for the station. This name information is stored for the station and is read/write accessible via Snmp requests made to the station for OID 1.3.6.1.2.1.1.5.0. |
| Location | text | Configures the system location information for the station. This location information is stored for the station and is read/write accessible via Snmp requests made to the station for OID 1.3.6.1.2.1.1.6.0 |
| Snmp Received Requests | drop-down list | Configures the ability for Snmp request messages to be received by the station (only supports receiving GET, GETNEXT, or SET Snmp V1 or Snmp V2 messages) is enabled or disabled. When enabled, reception of Snmp request messages from external Snmp sources is possible (subject to the constraints placed on the reception of Snmp requests by the next six property fields). When disabled, reception of Snmp requests is not possible and any requests sent to it will be dropped. |
| Recieve Config | additional properties | Configures additional parameters to receive Snmp requests from external Snmp sources. |
| Send Config | additional properties | Configures additional parameters to send Snmp requests from external Snmp sources. |
| Ignore Requests From Unrecognized Sources | true or false (default)
|
Configures whether to enable or disable the ability for Snmp request messages to be received from only recognized sources
(specified in the 'Recognized Sources' property). When set to true, a received Snmp request message is first checked for its source Ip, and if this source Ip matches any one of the source
Ip addresses specified in the 'Recognized Sources' field, the request is processed. If the source Ip does not match, then
the request is disregarded. When set to false, Snmp requests from any source Ip will be processed.
|
| Recognized Sources | additional properties | Configures source Ip addresses to specify a list of recognized network managers. This list is used if the 'Snmp Receive Requests' and 'Only Accept Requests From Recognized Sources' properties are both enabled. It contains a list of source Ip addresses that are searched whenever an incoming Snmp request is received, and if the source of that request matches a source Ip in this list, then the request will be processed. Otherwise, the request will be dropped. Useful for security purposes to ensure that the station only responds to known sources. |
| Check Community of Request | true (default) or false
|
Configures the community string field on a received Snmp request message before processing the request. When set to true, a received Snmp request message is first checked for its community string, and if this community string matches the community
string specified in the 'Read Only Community' field (for GET or GETNEXT requests) or the 'Read Write Community' field (for
GET, GETNEXT, or SET requests), the request is processed. If the community string does not match for the appropriate read/write
access, then the request is disregarded. When set to false, Snmp requests with any community string field will be processed.
|
| Read only Community | public (default) | Configures the community string field that incoming Snmp request messages must contain in order to process a read-only request (GET or GETNEXT request). The default value is public. |
| Read Write Community | public (default) | Configures the community string field that incoming Snmp request messages must contain in order to process a read-write request
(GET, GETNEXT, or SET request). The default value is “public”.
NOTE: This is valid if the 'Check Community On Requests' property is enabled.
|
| Snmp Receive Traps | true or false (default)
|
the ability for Snmp trap messages to be received by the station. When set to true, reception of Snmp trap messages from external Snmp devices is enabled, and any received trap messages will be routed to
the Alarm Class specified by the 'Alarm Class For Received Traps' property, subject to the constraints of the 'Only Process
Recognized Traps' property.
|
| Trap Config | additional properties | Configures additional parameters for Trap configuration. |
| Default Network Manager IP Address | Ip Address | Configures the default Ip address of the network manager to use for reporting information. |
| Default Network Manager Traps Port | numeric (defaults to 162) | Configures the port to use for outgoing Snmp trap messages sent to the default network manager (i.e. the port on the default network manager where Snmp trap messages are received). |
| Default Network Manager Snmp Version | numeric | Configures the Snmp version whether it is Snmp V1 or Snmp V2. |
| Default Network Manager Traps Community | text (defaults to public) | Configures the community string field to use for outgoing Snmp trap messages (sent to the default network manager). |
| Snmp Alarm table Capacity | numeric | Configures the maximum size of the Snmp Alarm Table. The default size is 500 records. Using this property, you can disable the Snmp Alarm Table by setting the value to zero. The purpose of limiting the table size is to conserve memory. You can also choose to disable Snmp alarm storage by choosing to set the SnmpRecipient’s Snmp Alarm Table property to Do not Store Received. |
| Local Device | container | Added by default with Snmp network. |
