This security object is set by the network manager
to configure what type of device is permitted to
connect to the port. One of the following values:
allowEndNodesOnly - only non-promiscuous
end nodes permitted.
allowPromiscuousEndNodes - promiscuous or non-
promiscuous end nodes
permitted
allowEndNodesOrRepeaters - repeaters or non-
promiscuous end nodes
permitted
allowAnything - repeaters, promiscuous
or non-promiscuous end
nodes permitted
For a port for which icfVgPortType is equal to
'cascadeInternal' or 'cascadeExternal', the
corresponding instance of this object may not be set
to 'allowEndNodesOnly' or 'allowPromiscuousEndNodes'.
The agent must reject a SET of this object if the
value includes no capabilities that are supported by
this port's hardware, as defined by the values of the
corresponding instances of
icfVgPortSupportedPromiscMode and
icfVgPortSupportedCascadeMode.
