User Manual

56UPS Network Management Card 3 User Guide
When using StruxureWare Data Center Expert to manage a UPS on the public network of an StruxureWare
system, you must have SNMPv1 or SNMPv3 enabled in the NMC interface. Read access will allow the
StruxureWare device
to receive traps from the NMC, but Write access is required while you use the NMC
user interface to set the StruxureWare device as a trap receiver.
For detailed information on enhancing and managing the security of your system, see the Security
Handbook, available on the APC website.
SNMPv1.
Path: Configuration > Network > SNMPv1 > Access and Access control
Use Access to enable or disable SNMP version 1 as a method of communication with the NMC.
Use of SNMPv2c is supported by the SNMPv1 options.
Access Control. You can configure up to four access control entries to specify which Network Management
Systems (NMSs) have access to the NMC. To edit, click a community name.
By default one entry is assigned to each of the four available SNMPv1 communities. You can edit these
settings to apply more than one entry to any one community to grant access by several specific IPv4 and IPv6
addresses, host names, or IP address masks.
• By default, a community has access to the NMC from any location on the network.
• If you configure multiple access control entries for any one community name, it means that one or more
of the other communities have no access to the device.
Community Name: The name that a Network Management Station (NMS) must use to access the community.
The maximum length is 15 ASCII characters.
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.
SNMPv1 is disabled by default. The Community Name must be set before SNMPv1 communications
can be established.
