This table contains objects which control access to the agent over IP. Access is restricted to only the hosts listed in this table. If a station does not have read-write-allow-telnet(4) access to a unit, then this table is not accessible, e.g. GET or SET messages accessing this table from stations will have an authentication error returned. GET NEXTs on this MIB from such stations will simply skip over this table. Care must be taken when modifying this table. A network management station can inadvertently modify this table so that it no longer has read-write-allow-telnet(4) access. If this occurs, then this table can only be modified from another network management station with write access, via telnet, or via a direct connection to the unit's primary serial port. Access to this unit via SNMP and Telnet can also be blocked if all the entries in this table and the cpqnCommunityAccessIPXTable are deleted. In this case, this table can only be modified via a direct connection via the primary serial port using the unit's user interface. This table can be set to factory values using the user interface accessed by Telnet or a direct connection to the unit's primary serial port. This table will also be set to factory values when cpqnUnitReset is set to reset-to-factory-values(4).
