The link table is intended to organize and communicate any
information the agent possesses 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 a management application to both LIST
and MAP the elements of the framework. With this goal in mind, the
agent SHOULD include as much information 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 in accord with the following structure;
however, the information MUST include either a nonzero
fcConnUnitNodeId OR a nonzero fcConnUnitPortWwn for each end
of the link.
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 should 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.
