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 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.
