Object

column Bits

This object describes 2 attributes of this protocol
directory entry.
              
The presence or absence of the 'extensible' bit describes
whether this protocol directory entry can be extended
by the user by creating protocol directory entries that are
children of this protocol.
              
An example of an entry that will often allow extensibility is
              
'ip.udp'.  The probe may automatically populate some children
of this node, such as 'ip.udp.snmp' and 'ip.udp.dns'.
A probe administrator or user may also populate additional
children via remote SNMP requests that create entries in this
table.  When a child node is added for a protocol for which the
probe has no built-in support extending a parent node (for
which the probe does have built-in support),
that child node is not extendable.  This is termed 'limited
extensibility'.
              
When a child node is added through this extensibility
mechanism, the values of protocolDirLocalIndex and
protocolDirType shall be assigned by the agent.
              
The other objects in the entry will be assigned by the
manager who is creating the new entry.
              
This object also describes whether this agent can
recognize addresses for this protocol, should it be a
network-level protocol.  That is, while a probe may be able
to recognize packets of a particular network-layer protocol
and count them, it takes additional logic to be able to
recognize the addresses in this protocol and to populate
network-layer or application-layer tables with the addresses
in this protocol.  If this bit is set, the agent will
recognize network-layer addresses for this protocol and
populate the network- and application-layer host and matrix
tables with these protocols.
              
Note that when an entry is created, the agent will supply
values for the bits that match the capabilities of the agent
with respect to this protocol.  Note that since row creations
usually exercise the limited extensibility feature, these
bits will usually be set to zero.
