Add an SNMP Notification User
The Add Notification User dialog lets you add a security user authorized to receive notifications. For
SNMPv3 notifications, a security user is required. When you add a notification agent, you select a security
user from the list of notification users that have been added.
Notification users aren’t needed or used for SNMPv2c.
To add a notification user
1 Go to Admin > Local Cluster > SNMP Settings.
2 Click Add User.
3 Configure the following settings in the Add Notification User dialog box.
Community For SNMPv2c, specifies the context for the information, which is the SNMP
group to which the devices and management stations running SNMP belong.
The RealPresence DMA system has only one valid context—by default,
public—which is identified by this Community name. The RealPresence
DMA system will not respond to requests from management systems that do
not belong to its community.
V3 Local Engine Id For SNMPv3 only.
Displays the RealPresence DMA system contextEngineID for SNMPv3.
Security User For SNMPv3 only.
Specifies the security name required to access a monitored MIB object.
This name cannot be snmpuser.
Field Description
Security user The user name of the security user authorized to actively retrieve SNMP data.
Authentication type The authentication protocol used to create unique fixed-sized message digests of a
variable length message.
The RealPresence DMA system implements communication with authentication and
privacy (the authPriv security level, as defined in the USM MIB).
Authentication type options:
• MD5–Creates a digest of 128 bits (16 bytes)
• SHA–Creates a digest of 160 bits (20 bytes)
Both methods include the authentication key with the SNMPv3 packet and then
generate a digest of the entire SNMPv3 packet.
Authentication password
Confirm password
The authentication password that’s used, together with the local engine ID, to create
the authentication key included in the MD5 or SHA message digest.
