Configuring SNMP Engine ID

The [SNMPEngineIDString] ini file parameter configures the SNMP engine ID. The ID can be a string of up to 36 characters. Once defined, the device must be restarted for the parameter to take effect.

The default value is 00:00:00:00:00:00:00:00:00:00:00:00 (12 Hex characters). The provided key must be set with 12 Hex values delimited by ‘:’.

If the supplied key does not pass validation of the 12 Hex values input or it is set with the default value, the engine ID is then generated, according to RFC 3411.

Before setting this parameter, all SNMPv3 users must be deleted, otherwise the configuration is ignored.

When the device operates in HA mode, the SNMPEngineIDString parameter has the same value for both active and redundant devices (i.e., system identifier). If the devices return to Standalone mode (i.e., non-HA mode), you must configure the parameter to a NULL value (i.e., no value) on both devices. When the devices restart to the standalone mode, each device automatically sets this parameter to a unique value based on its serial number (S/N).
