Maintaining SNMP computer system templates and configuration files

You can use the Computer Systems view to maintain a list of templates that can be used to discover network devices.

You can partially define a device, link this definition to a template and then use the template to discover more information about the device.

An OID is assigned to a device by the manufacturer and is unique to the make and model of the device. Similar devices of the same model have the same OID. You can typically determine the type of device you have found by searching the Web. This value can also be obtained for the device by querying the SNMPv2-MIB tables for values under the sysObjectID 1.3.6.1.2.1.1.2.

The SNMP templates and their configuration files are loaded dynamically during each discovery. It is not necessary to restart the TADDM server after modifying the SNMP templates and their configuration files. It is important to use the correct syntax and enter the correct values when editing templates and configuration files.

If your devices are not correctly classified after a discovery, review the SnmpMib2Sensor log or the DiscoveryManager log file.

The following results show different OIDs discovered through SNMP scans of four Foundry devices. In scanning a test environment, the OIDs outlined in Table 1 were discovered. You can perform an Internet search to determine the type of devices. Alternatively, you can ask your network team to identify the specific device types.

Table 1. Foundry OID mapping example
Foundry device OID Description
Foundry FESX448-PREM .1.3.6.1.4.1.1991.1.3.34.2.1.1.2 Router
Foundry FastIron SX .1.3.6.1.4.1.1991.1.3.36.6.2 Unknown (classified as a switch for our testing)
Foundry BigIron RX .1.3.6.1.4.1.1991.1.3.40.1.2 Unknown (classified as a switch for our testing)
Foundry NetIron MLX .1.3.6.1.4.1.1991.1.3.44.2.2 Unknown (classified as a router for our testing)

You can create templates to classify discovered Foundry devices.
