OSI object classes

The VTAM® topology agent provides topology data for the network resources that VTAM manages. To do this the VTAM resources must first be viewed in the object-oriented context of the OSI object definitions. The following list shows the OSI object classes supported by the VTAM topology agent:

crossDomainResource
crossDomainResourceManager (valid only in replies, not requests)
definitionGroup
appnEN
interchangeNode
lenNode
logicalLink
logicalUnit
luCollection
luGroup
logicalUnitIndex
migrationDataHost
appnNN
port
appnRegisteredLu
snaLocalTopo
snaNetwork
appnTransmissionGroup (valid only in replies, not requests)
subareaTransmissionGroup (valid only in replies, not requests)
t2-1Node
t4Node
t5Node
virtualRoute (valid only in replies, not requests)
virtualRoutingNode (valid only in replies, not requests)

Each object class definition contains a list of attributes for that class. The attributes supported by VTAM are listed by object class in VTAM topology agent object and attribute tables. Only the object classes that are valid in requests are listed.

Although some of the object classes have obvious meanings, some represent resources in VTAM that are known by different names. The next sections address the mapping of VTAM resources back to these OSI object classes. Note that some of the OSI classes do not represent existing VTAM objects; these OSI objects generally represent a group of VTAM resources. These object types are described more fully in VTAM topology monitoring.
