Specifying a Remote Engine ID

To send inform messages to an SNMPv3 user on a remote device, you must first
specify the engine identifier for the SNMP agent on the remote device where the
user resides. The remote engine ID is used to compute the security digest for
authenticating and encrypting packets sent to a user on the remote host.
SNMP passwords are localized using the engine ID of the authoritative agent. For
informs, the authoritative SNMP agent is the remote agent. You therefore need to
configure the remote agent's SNMP engine ID before you can send proxy requests
or informs to it.
The engine ID can be specified by entering 9 to 64 hexadecimal characters (5 to 32
octets in hexadecimal format). If an odd number of characters are specified, a
trailing zero is added to the value to fill in the last octet. For example, entering the
value "123456789" sets the engine ID as "1234567890".

Configuring SNMPv3 Users

Each SNMPv3 user is defined by a unique name. Users must be configured with a
specific security level and assigned to a group. The SNMPv3 group restricts users to
a specific read, write, and notify view.
Command Attributes
• User Name – The name of user connecting to the SNMP agent.
(Range: 1-32 characters)
• Group Name – The name of the SNMP group to which the user is assigned.
(Range: 1-32 characters)
• Model – The user security model; SNMP v1, v2c or v3.
• Level – The security level used for the user:
- noAuthNoPriv – There is no authentication or encryption used in SNMP
communications. (This is the default for SNMPv3.)
- AuthNoPriv – SNMP communications use authentication, but the data is not
encrypted (only available for the SNMPv3 security model).
- AuthPriv – SNMP communications use both authentication and encryption (only
available for the SNMPv3 security model).
• Authentication – The method used for user authentication.
(Options: MD5, SHA; Default: MD5)
