access

You can configure up to four access control entries to specify which NMSs have access to this

control

device. The opening page for access control, by default, assigns one entry to each of the four user

 

profiles, but you can edit these settings to apply more than one entry to any user profile to grant

 

access by several specific IP addresses, host names, or IP address masks.

 

• If you leave the default access control entry unchanged for a user profile, all NMSs that use that

 

profile have access to this device.

 

• If you configure multiple access entries for one user profile, the limit of four entries requires that

 

one or more of the other user profiles must have no access control entry. If no access control

 

entry is listed for a user profile, no NMS that uses that profile has any access to this device.

 

To edit the access control settings for a user profile, click its user name.

 

Access: Mark the Enable checkbox to activate the access control specified by the parameters in

 

this access control entry.

 

User Name: From the drop-down list, select the user profile to which this access control entry

 

will apply. The choices available are the four user names that you configure through the user

 

profiles option on the left navigation menu.

NMS IP/Host Name: The IP address, IP address mask, or host name that controls access by the NMS. A host name or a specific IP address (such as 149.225.12.1) allows access only by the NMS at that location. An IP address mask that contains 255 restricts 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.

FTP Server

Path: Administration > Network > FTP Server

The FTP Server settings enable (by default) or disable access to the FTP server and specify the TCP/IP port (21 by default) that the FTP server uses to communicate with the Rack PDU. The FTP server uses both the specified port and the port one number lower than the specified port.

You can change the Port setting to the number of any unused port from 5001 to 32768 for added security. Users must then use a colon (:) to specify the non-default port number. For example, for port 5001 and IP address 152.214.12.114, the command would be ftp 152.214.12.114:5001.

Note: FTP transfers files without encryption. For higher security, disable the FTP server, and transfer files with SCP. Selecting and configuring Secure SHell (SSH) enables SCP automatically.

At any time that you want a Rack PDU to be accessible for management by StruxureWare Dat Center Expert, FTP Server must be enabled in the Rack PDU interface.
