Monitoring System Health Using SNMP

AsyncOS supports system status monitoring via Simple Network Management Protocol (SNMP) versions v1, v2, and v3.

• To enable and configure SNMP, use the snmpconfig command in the command-line interface.

• MIBs are available from http://www.cisco.com/c/en/us/support/security/content-security-management-appliance/tsd-products-support-series-home.html use the latest available files.

• The use of SNMPv3 with passphrase authentication and DES Encryption is mandatory to enable this service. (For more information on SNMPv3, see RFCs 2571-2575.) You are required to set a SNMPv3 passphrase of at least 8 characters to enable SNMP system status monitoring. The first time you enter a SNMPv3 passphrase, you must re-enter it to confirm. The snmpconfig command “remembers” this phrase the next time you run the command.

• When setting up SNMP to monitor connectivity:

  When entering the url-attribute while configuring a connectivityFailure SNMP trap, determine whether the URL is pointing at a directory or a file.

  • If it is a directory, add a trailing slash (/)

  • If it is a file, do not add a trailing slash

• Additional information about using SNMP with AsyncOS is available in the online help for your web or email security appliance.
