SNMP

SNMPv1. 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 InfraStruXure Central to manage a cooling unit on the public network of a system, you must have SNMP enabled in the cooling unit. Read access will allow InfraStruXure Central to receive traps from the cooling unit, but Write access is required while you use the interface of the cooling unit to set InfraStruXure Central as a trap receiver.

For detailed information on enhancing and managing the security of your system, see the Security Handbook, available on the Utility CD or from the APC Web site, www.apc.com.

Use the options under SNMP on the left navigation menu to configure the following:

Option

Description

 

 

access

Enable SNMPv1 Access: Enables SNMP version 1 as a method of communication with this

 

device.

 

 

access

You can configure up to four access control entries to specify which Network Management

control

Systems (NMS) 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 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 a NMS on the 149.225.12 segment.

149.225.255.255: Access only by a NMS on the 149.225 segment.

149.255.255.255: Access only by a 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 a 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 control console.

Write+: GETS and SETS at any time.

Disabled: No GETS or SETS at any time.
