47InRow RC/RD/RP (600 mm) User’s Guide
SNMPv3. For SNMP GETs, SETs, and trap receivers, SNMPv3 uses a system of user profiles to identify
users. An SNMPv3 user must have a user profile assigned in the MIB software program to perform GETs
and SETs, browse the MIB, and receive traps.
Note: To use SNMPv3, you must have a MIB program that supports SNMPv3.
Note: The cooling unit supports only MD5 authentication and DES encryption.
Option Description
access SNMPv3 Access: Enables SNMPv3 as a method of communication with this device.
user
profiles
By default, lists the settings of four user profiles, configured with the user names "apc snmp
profile1" through "apc snmp profile 4", and no authentication and no privacy (no encryption of
data). 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 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 that ensures the privacy of the data
(by means of encryption) that a NMS is sending to this device or receiving from this device
through SNMP v3.
Authentication Protocol: The APC implementation of SNMPv3 supports MD5 authentication.
Authentication will not occur unless MD5 is selected here.
Privacy Protocol: The APC implementation of SNMPv3 supports DES as the protocol for
encrypting and decrypting data. Privacy of transmitted data requires that DES is selected here.
Note: You cannot select the privacy protocol if no authentication protocol is selected.
