SNMP is off by default.
SNMP SET operations (configuration) are not implemented.
AsyncOS supports SNMPv1, v2, and v3.
The use of SNMPv3 with password 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

command 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

version 1 and 2 requests must have a matching community string.
Cisco IronPort 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 IronPort appliances.
IRONPORT-SMI.txt — defines the role of the ASYNCOS-MAIL-MIB in
IronPort’s SNMP managed products.
