Security 87
Changing the value of engineID may have important side-effects, altering both the acceptable
SNMP community string and command line password for a device. If this occurs, re-configure the
device’s authorized users.
CAUTION:
When creating the SNMPv3 user account for OpenManage Network Manager ensure that all MIBs are
included in that user’s view. If you discover a device using SNMPv3 but do not expose, for example, the
RFC1213 system MIB to the user account initiating this discovery OpenManage Network Manager looks
like it cannot communicate using SNMPv3.
This screen has the following fields:
General Parameters
- ID — (Required) This entry must be unique; it identifies the authentication object. The ID is
only a label name under which you store the authentication and has no effect on the SNMPv3
Authentication itself.
-
Use for EMS —Disregard. This entity does not support SNMP v3.
-
Select SNMP v3 Parameters —From the pick list.
-
Security Level —Defines the three security levels that can be used. They are:
No Authentication–Sends SNMP messages without authentication and without privacy.
This requires only a valid User ID, known by the device's SNMP agent.
Authentication (No Privacy)—Sends SNMP messages with authentication but without pri-
vacy. Requires only a valid User ID and a password.
Authentication with Privacy—Sends SNMP messages with authentication and privacy. This
requires a valid User ID, password, authentication Protocol and Privacy Key.
NOTE:
Supported authentications include: No authentication No privacy, MD5 or SHA Authentication with No
privacy*, and MD5 Authentication with DES. Privacy encryption 3DES and AES are not currently
supported.
- User ID —Specifies the User Name for this object. The Security user name represents the user in
a format that is Security Model-independent.
-
Password — Specify the password for this user.
-
Confirm Password — Confirm the password.
-
Authentication Protocol — Select the protocol from the pick list ( MD5 or SHA ). Used with the
Privacy Key to produce a secret key in which to validate the connection.
