Description
The link table is intended to organize and communicate any
Link Table
information the agent which would assist a management application
to discover the CONNECTIVITY UNITS in the framework and the
TOPOLOGY of their interconnect. That is, the goal is to assist the
management application not only to LIST the elements of the
framework, but to MAP them.
With this goal, the agent SHOULD include as much as it possesses
about any links from its own connectivity units to others, including
links among its own units.
An agent SHOULD include partial information about links if it is not
able to fully define them. For an entry to be considered to be valid,
both the X (local) and the Y (remote) need to have one valid value.
If the agent is able to discover links which do not directly attach to
members of its agency and its discovery algorithm gives some
assurance the links are recently valid, it MAY include these links.
Link information entered by administrative action MAY be included
even if not validated directly if the link has at least one endpoint in
this agency, but SHOULD NOT be included otherwise.
A connectivity unit can fill the table in as best it can. One of the
methods to fill this in would be to use the RNID ELS (ANSI
document 99-422v0). This allows one to query a port for the
information needed for the link table.
This table is accessed either directly if the management software has
an index value or via GetNexts. The value of the indexes are not
required to be contiguous. Each entry created in this table will be
assigned an index. This relationship is kept persistent until the entry
is removed from the table or the system is reset. The total number of
entries are defined by the size of the table.
