SNMP
SNMPv1.
Path: Administration > Network > SNMPv1 > options
All user names, passwords, and community names for SNMP are transferred over the network as plain
text. If your network requires the high security of encryption, disable SNMP access or set the access for
each community to Read. (A community with Read access can receive status information and use SNMP
traps.)
When using StruxureWare to manage the PDU on the public network of an StruxureWare system, you
must have SNMP enabled in the PDU interface. Read access will allow StruxureWare to receive traps
from the PDU , but Write access is required while you use the interface of the PDU to set StruxureWare
as a trap receiver.
For detailed information on enhancing and managing the security of your system, see the Security
Handbook, available from the APC Web site, www.apc.com.
Option Description
access Enable SNMPv1 Access: Enables SNMP version 1 as a method of communication with this
device.
access
control
You can configure up to four access control entries to specify which NMSs have access to this
device. The opening page for access control, by default, assigns one entry to each of the four
available SNMPv1 communities, but you can edit these settings to apply more than one entry to any
community to grant access by several specific IP addresses, host names, or IP address masks. To
edit the access control settings for a community, click its community name.
• If you leave the default access control entry unchanged for a community, that community has
access to this device from any location on the network.
• If you configure multiple access control entries for one community name, the limit of four entries
requires that one or more of the other communities must have no access control entry. If no access
control entry is listed for a community, that community has no access to this device.
Community Name: The name that a Network Management System (NMS) must use to access the
community. The maximum length is 15 ASCII characters, and the default community names for the
four communities are public, private, public2, and private2.
NMS IP/Host Name: The IP address, IP address mask, or host name that controls access by NMSs.
A host name or a specific IP address (such as 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 Web interface or command
line interface.
• Write+: GETS and SETS at any time.
• Disabled: No GETS or SETS at any time.
