This document describes which Simple Network Management Protocol (SNMP) traps are supported by AsyncOS.
Does AsyncOS support SNMP monitoring?
The Cisco AsyncOS operating system supports system status monitoring via SNMP. AsyncOS supports SNMPv1, v2, and v3.
This includes Cisco's Enterprise Management Information Base (MIB), ASYNCOS-MAIL-MIB. The ASYNCOS-MAIL-MIB helps administrators better monitor system health. In addition, this release implements a read-only subset of MIB-II as defined in RFCs 1213 and 1907. (For more information on SNMP, see RFCs 1065, 1066, and 1067.)
Use the snmpconfig command in order to configure SNMP system status for the appliance. After you choose and configure values for an interface, the appliance responds to SNMPv3 GET requests. These Version 3 requests must include a matching password. By default, Version 1 and 2 requests are rejected. If enabled, Version 1 and 2 requests must have a matching community string.
Cisco Systems provides an enterprise MIB as well as a Structure of Management Information (SMI) file:
- ASYNCOS-MAIL-MIB.txt - an SNMPv2 compatible description of the Enterprise MIB for Cisco appliances.
- IRONPORT-SMI.txt - defines the role of the ASYNCOS-MAIL-MIB in IronPort?s SNMP managed products.
Both MIB files can be located from the Cisco Email Security Appliance Product Support page.
Please refer to the Managing and Monitoring via the CLI chapter of the Email User Guide for full details regarding SNMP monitoring.
