USER’S GUIDE

Switched Rack PDU

SNMPv3 (Administration>Network>SNMPv3>options)

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.

To use SNMPv3, you must have a MIB program that supports SNMPv3.

The Switched Rack PDU 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.
