Chapter 50 Configuring Inspection for Management Application Protocols
SNMP Inspection
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 46-6.
