Configuring Protocols and Maps for Inspection
Configuring SNMP Maps
Use the Add and Edit SNMP Map dialog boxes to define maps for SNMP inspection. An SNMP policy
map lets you change the default configuration values used for SNMP application inspection.
SNMP application inspection lets you restrict SNMP traffic to a specific version of SNMP. Earlier
versions of SNMP are less secure; therefore, denying certain SNMP versions may be required by your
security policy. The security appliance can deny SNMP versions 1, 2, 2c, or 3. You control the versions
permitted by creating an SNMP map. You then apply the SNMP map when you enable SNMP inspection.
Navigation Path
Select Manage > Policy Objects, then select Maps > Policy Maps > Inspect > SNMP from the Object
Type selector. Right-click inside the work area, then select New Object, or right-click a row and select
Edit Object.
