SNMP Inspection Overview

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 ASA 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 according to the “Configuring Application Layer Protocol Inspection” section on page 10-7.

Select SNMP Map

Add/Edit Service Policy Rule Wizard > Rule Actions > Protocol Inspection Tab >

Select SNMP Map

The Select SNMP Map dialog box lets you select or create a new SNMP map. An SNMP map lets you change the configuration values used for SNMP application inspection. The Select SNMP Map table provides a list of previously configured maps that you can select for application inspection.

Fields

•Use the default SNMP inspection map—Specifies to use the default SNMP map.

•Select an SNMP map for fine control over inspection—Lets you select a defined application inspection map or add a new one.

•Add—Opens the Add Policy Map dialog box for the inspection.

SNMP Inspect Map

Configuration > Global Objects > Inspect Maps > SNMP

The SNMP pane lets you view previously configured SNMP application inspection maps. An SNMP map lets you change the default configuration values used for SNMP application inspection.

Fields

•Map Name—Lists previously configured application inspection maps. Select a map and click Edit to view or change an existing map.

•Add—Configures a new SNMP inspect map.

•Edit—Edits the selected SNMP entry in the SNMP Inspect Maps table.

•Delete—Deletes the inspect map selected in the SNMP Inspect Maps table.

Add/Edit SNMP Map

Configuration > Global Objects > Inspect Maps > SNMP > Add/Edit SNMP Map (You can get to this dialog box through various paths.)
