Local engine ID When SNMP monitoring is enabled, displays the
administratively unique identifier for the default context
of the system’s SNMP protocol engine.
For SNMPv3, the local engine ID is used in generating
the authentication and encryption keys.
Security user For SNMPv3, specify the user name of the read-only
SNMP access user (that is, the security user authorized
to actively retrieve SNMP data).
Authentication type For SNMPv3, specify the authentication protocol. These
protocols are used to create unique fixed-size message
digests of a variable length message.
Possible values for authentication protocol are:
•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
For SNMPv3, specify the authentication password that’s
used (along with the local engine ID) to create the
authentication key used by the MD5 or SHA message
digest.
Encryption type For SNMPv3, specify the privacy protocol for the
connection between the management system and the
SNMP agent:
•DES—Uses a 56-bit key with a 56-bit salt to encrypt
the SNMPv3 packet.
•AES—Uses a 128-bit key with a 128-bit salt to
encrypt the SNMPv3 packet.
Encryption password
Confirm password
For SNMPv3, specify the password that’s used (along
with the local engine ID) to create the encryption key
used by the privacy protocol.
Notification Users
(USM) Lists the notification users that have been created.
For SNMPv3, these are security users authorized to
receive notifications (Traps or Informs), but not to
actively retrieve SNMP data. Notification agents can
send notifications to users in this list.
Notification Agents Lists the notification agents that have been created. The
system supports up to eight notification agents.
The icon to the left of each entry indicates whether that
agent is enabled.
Address The IP address, port number, and transport protocol
used for this agent.
