What is a SNMP Mask?
As defined in RFC2575 (http://www.ietf.org/rfc/rfc2575.txt), an SNMP mask is an optional parameter of the set snmp view command. You can use a mask to modify a view inclusion, designating certain octets of an OID string as wildcard don't care values. Once defined, you can view within a MIB branch only those leaves associated with specific items, such as designated port numbers, MAC addresses, and IP addresses. This is done using a MIB browser such as that offered within the NetSight suite of products.
SNMP Mask Management
Mask management consists in selecting the OIDs to recover from the SNMP agents. Using the SNMP poller, there are three different ways of collecting them.
Watch4net APG only supports numeric values as data. String values that have no numeric equivalent must be collected as properties. There is no history on properties and they are modified only once per day (this may be changed in APG s main configuration).
SNMP/OIDs Masks Configuration
The OIDs Masks Configuration refers to the snmp-masks.xml file. You can import and merge (or overwrite) the SNMP Masks configuration. You have a view of all installed SNMP Masks. In this section, you can either add or delete a mask. Keep in mind that a mask is a group of OIDs definition.
Installing a new SNMP ReportPack
Installing a new SNMP ReportPack was made easy in APG. Just upload your SNMP mask and translation file. You can update several snmp-masks (include them in the same file). You can then push the configuration to the poller.
