access
control
You can configure up to four access control entries to specify which Network
Management Systems (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 IPv4 and IPv6 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 an 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 IPv4 or IPv6 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.
• Disable: No GETS or SETS at any time.
