access | You can configure up to four access control entries to specify which NMSs have access to this device. |
control | 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 check box to activate the access control specified by the parameters in this |
| access control entry. |
| User Name: From the |
| 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 contain 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.
Modbus
Path: Administration > Network > Modbus > serial (or TCP)
Enable or disable access to the Modbus serial or TCP interface by selecting or clearing the Enable check box.
Set the connection parameters for the Modbus connection - a port number for the TCP connection, or the parameters for the serial connection. The default serial connection settings are 19200 baud, 1 start bit, 8 data bits, even parity, and 1 stop bit.
Note: If you select None, the Modbus master should be set to use 2 stop bits. For Even or Odd, use 1 stop bit.
Set the unique ID for the device by providing a value in the Target Unique ID field. The value must be between 1 and 247 (inclusive).
When you are finished making your selections, click Apply to save your changes.
