Resolution

Spectrum does not have any options to discover a device in SNMPv3 that is dependent upon an SNMP context, but if the device is setup for SNMPv1 or SNMPv2, we can model it as SNMPv1/SNMPv2 and then change the device to SNMPv3 with SNMP Context by following this procedure.

Add Context Name Information

You can add the SNMPv3 context name value to be sent with SNMPv3 messages for a particular device.

Follow these steps:

1. Select the model that you want to modify, and click the Information tab in the Component Detail panel.

2. Expand the CA Spectrum Modeling Information subview, and click set in the SNMP Community String field.

3. Add the context name value to the SNMP Community String field. For example, if the current SNMP community string is:

    #v3/P:authPass:privPass/myuserid

    or 

    #v3/A:authPass/myuserid

 

4. To insert a context name value of ‘quark,’ add ‘quark’ to the SNMP community string as follows:

   #v3/P:authPass:privPass/quark/myuserid 

   or

   #v3/A:authPass/quark/myuserid
