Table 15-2Information on the SNMP Settings page (continued)

	Setting	Description
	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	For SNMPv3, specify the authentication password that’s
	password	used (along with the local engine ID) to create the
	Confirm password	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	For SNMPv3, specify the password that’s used (along
	Confirm password	with the local engine ID) to create the encryption key
		used by the privacy protocol.
	Notification Users	Lists the notification users that have been created.
	(USM)	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.
