Information About SNMP
SNMP is an application-layer protocol that facilitates the exchange of management information between
network devices and is part of the TCP/IP protocol suite. This section describes SNMP and includes the
following topics:
• Information About SNMP Terminology, page 79-2
• Information About MIBs and Traps, page 79-2
• SNMP Object Identifiers, page 79-3
• SNMP Physical Vendor Type Values, page 79-5
• Supported Tables in MIBs, page 79-11
• Supported Traps (Notifications), page 79-12
• SNMP Version 3, page 79-15
The ASA provides support for network monitoring using SNMP Versions 1, 2c, and 3, and supports the
use of all three versions simultaneously. The SNMP agent running on the ASA interface lets you monitor
the ASA and through network management systems (NMSs), such as HP OpenView. The ASA supports
SNMP read-only access through issuance of a GET request. SNMP write access is not allowed, so you
cannot make changes with SNMP. In addition, the SNMP SET request is not supported.
