NMS IP/Host Name: The IPv4 or IPv6 address, IP address mask, or host name that controls access by NMSs.
A host name or a specific IP address (for example, 149.225.12.1) allows access only by the NMS at that
location. IP addresses that contain 255 restrict access as follows:
• 149.225.12.255: Access only by an NMS on the 149.225.12 segment.
• 149.225.255.255: Access only by an NMS on the 149.225 segment.
• 149.255.255.255: Access only by an NMS on the 149 segment.
• 0.0.0.0 (the default setting) which can also be expressed as 255.255.255.255: Access by any NMS on
any segment.
Access Type: The actions an NMS can perform through the community.
• Read: GETS only, at any time
• Write: GETS at any time, and SETS when no user is logged onto the UI or command line interface.
• Write+: GETS and SETS at any time.
• Disable: No GETS or SETS at any time.
SNMPv3.
Path: Configuration > Network > SNMPv3 > Access, User Profiles , and Access Control
For 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, to browse the MIB,
and to 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 this 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 profile4, with 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.
It also verifies that the message has not been changed during transmission, and that the message was
communicated in a timely manner. This indicates 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 that an NMS is sending to or receiving from this device through
SNMPv3, by using encryption.
• Authentication Protocol: The implementation of SNMPv3 supports SHA and MD5 authentication.
One of these must be selected.
• Privacy Protocol: The implementation of SNMPv3 supports AES and DES as the protocols for
encrypting and decrypting data. You must use both a privacy protocol and a privacy password,
otherwise the SNMP request is not encrypted.
In turn, you cannot select the privacy protocol if no authentication protocol is selected.
