Fibre Alliance MIB A Status Description Sequence current This is used with the fcConnUnitEventType to identify which object the event refers to. It can be the OID of a connectivity unit or of another object like fcConnUnitPortStatus[...] ::= { fcConnUnitEventEntry 6 } fcConnUnitEventDescr Syntax Max-Access Status Description Sequence SnmpAdminString read-only current The description of the event. ::= { fcConnUnitEventEntry 7 } 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. A-38 E/OS SNMP Support Manual
