ority has no effect on traffic exiting a node.)
A priority is also configured in Node Defaults, as well as for each logical port, SNA
PU, Bridge port/LLC2 Interface, IP interface, IPX interface, SVC subscriber, and
PVC connection. The device processor in the node uses these priorities to help
determine the order in which it will process protocols.
When configuring priorities, be careful to consider the types of
traffic being routed on other connections in the node.
