browse the MIB, and receive traps.
To use SNMPv3, you must have a MIB program that supports SNMPv3.
The
NMC supports SHA or MD5 authentication and AES or DES encryption.
Enable SNMPv3 access under access enables SNMP version 3 as a method of communication with this device.
Option Description
user
profiles
By default, lists the settings of four user profiles, configured with the user names apc snmp profile1
through apc snmp profile4, and no authentication and no privacy (no encryption). To edit the following
settings for a user profile, click a user name in the list.
User Name: The identifier of the user profile. SNMP version 3 maps GETs, SETs, and traps to a user
profile by matching the user name of the profile to the user name in the data packet being transmitted. A
user name can have up to 32 ASCII characters.
Authentication Passphrase: A phrase of 15 to 32 ASCII characters (apc auth passphrase, by
default) that verifies that the NMS communicating with this device through SNMPv3 is the NMS it
claims to be, that the message has not been changed during transmission, and that the message was
communicated in a timely manner, indicating that it was not delayed and that it was not copied and sent
again later at an inappropriate time.
Privacy Passphrase: A phrase of 15 to 32 ASCII characters (apc crypt passphrase, by default)
that ensures the privacy of the data (by means of encryption) that an NMS is sending to this device or
receiving from this device through SNMPv3.
Authentication Protocol: The implementation of SNMPv3 supports SHA and MD5 authentication.
Authentication will not occur unless an authentication protocol is selected.
Privacy Protocol: The implementation of SNMPv3 supports AES and DES as the protocols for
encrypting and decrypting data. Privacy of transmitted data requires that a privacy protocol is selected
and that a privacy passphrase is provided in the request from the NMS. When a privacy protocol is
enabled but the NMS does not provide a privacy passphrase, the SNMP request is not encrypted.
Note:You cannot select the privacy protocol if no authentication protocol is selected.
