        MIBII interfaces table. The table is indexed on ifIndex, but note that 
        there need not be an instance of a row in this table for each row in 
        the interfaces tabe. In practice this table can be considered to be an 
        augmentation of the ifTable, leading to a sparse table. Network 
        management applications must be aware of this distinction."

        disables the BootP mechanism for obtaining a bootP configuration. The 
        default value for this object for a specific interface depends on the

extIfIPAddress OBJECT-TYPE

      DESCRIPTION "The IP address hat this unit should use. This parameter can 
        be changed to indicate that a new IP config should be used. Note 
        however that changing this parameter by itself has no effect on the IP 
        stack configuration and the value written to this parameter will not 
        automatically be stored ready for the next restart. Instead the correct 
        sequence here is to write this value and any other IP stack parameter 
        changes and then write to the extIfIPApplyChanges object. When the 
        extIfIPApplyChanges object is set to 'apply' the IP stack will then 
        store the changes permanently and will restart the stack.

        The other changeable parameters are the sub-net mask and the default 
        router."

extIfNetMask OBJECT-TYPE

      DESCRIPTION "The sub-net mask for this interface. This parameter can be 
        set to indicate a requested change to the IP stack configuration. Such 
        a set operation does not take effect immediately. Read the description 
        of extIfIPAddress for a full description."

extIfDefaultRouter OBJECT-TYPE

      DESCRIPTION "This is the IP address of the default router to be used by 
        this interface.Changing this parameter has no effect until 
        extIfIPApplyChanges object is set. See extIfIPAddress for a full 
        description."

extIfIPApplyChanges OBJECT-TYPE

                  notApplicable (1),
                  storeAndApply (2)
      }
      ACCESS      read-write
      STATUS      mandatory
      DESCRIPTION "This parameter instructs the agent to make changes to the IP 
        configuration written to the device to be made permanent and to 
        reconfigure the stack to use the parameters and to optionally restart 
        the stack using these parameters. Note that if the device resets before 
        writing to this parameter the device will loose the configuration 
        changes.

        The correct procedure when changing the IP configuration is to write to 
        the individual parameters and then write to extIfIPApplyChnages.

        Writing 'storeAndApply (2)' will cause the parameters to be stored in 
        non-volatile storage and the stack then to be re-configured to use 
        those parameters. Note that applying the parameters to the stack may 
        cause the device containing the interface to reset. In this case there 
        will be a delay of a few seconds before the new configuration is 
        adopted which will allow the SNMP response to the set request to be 
        returned."

      DESCRIPTION "This is a string parameter allowing a short text name to be 
        associated with an interface. Note that not all interface types can be 
        named. If an instance of this object does not exist for a particular 
        interface then that interface cannot be named. Note that it is a 
        product specific decision to allow certain interfaces to be named. For 
        example it may be reasonable to name individual VLAN interfaces, but 
        not port interfaces."
