Explanation
 VTAM® issues
this message as part of a group of messages in response to the  following
commands:   DISPLAY TRACES,TYPE=ROUTE 
MODIFY TRACE,TYPE=ROUTE 
MODIFY TRACE,TYPE=ROUTE,BFRNUM=number_of_buffers

A complete description of the message group follows the example. 
  [IST350I DISPLAY TYPE = TRACES,TYPE=ROUTE]
 IST2154I ROUTE SELECTION TRACE IS ACTIVE - BFRNUM = number_of_buffers
 IST2156I STORAGE ALLOCATED TO ROUTE SELECTION TRACE = storage_amount
 IST314I END  

 IST350I  This message is issued in response to a DISPLAY TRACES,TYPE=ROUTE
command.  It  identifies the type of information in the display and
is always  TRACES,TYPE=ROUTE for this message group. 

 IST2154I  This message is issued to indicate that the APPN route selection
trace is  active.
In the message text: number_of_buffers
The maximum number of 40 KB buffers to be allocated for the  APPN
route selection trace table.

See the MODIFY TRACE command information
in z/OS Communications Server: SNA Operation and the APPN route
selection trace information in z/OS Communications Server: SNA Diagnosis Vol
1, Techniques and Procedures for more information about the APPN route
selection  trace.

 IST2156I  In the message text: storage_amount
The total number of bytes that is currently allocated to  the
APPN route selection trace table. This value is in the form xxxxxK,
where K is a  unit of measure in units of 1024 bytes. Storage
for the APPN route selection  trace is not all allocated when the
trace is activated, but is allocated in 40 K buffers as it is needed.
 If all of the storage allowed for the APPN route  selection trace
is not yet allocated, then the storage_amount value
is less than  40 K multiplied by the number_of_buffers value
displayed in message IST2154I.  For example, if the number_of_buffers value
in message IST2154I is 100 and only 50 buffers are currently  allocated,
then the storage_amount value is 2000 K.
