|

|
|
<p>Isolating a routing problem in an Advanced Peer-to-Peer
|
||
|
|
Networking® (APPN) network can be challenging. You can view the APPN information
|
||
|
|
to assist you in understanding the topology of network nodes and some of their
|
||
|
|
locations.</p>
|
||
|
|
<p>To display APPN Information, type the command DSPAPPNINF on a command line
|
||
|
|
and press F4. You can also select option 6 (Display APPN information) on the
|
||
|
|
Network Management menu.</p>
|
||
|
|
<p>The information the system displays, prints, or stores depends on the options
|
||
|
|
you select. The system displays additional options that are based on previous
|
||
|
|
options that are selected.</p>
|
||
|
|
<p>See the following scenario for help in using the DSPAPPNINF command:</p>
|
||
|
|
<p></p>
|
||
|
|
<ul>
|
||
|
|
<li>Type DSPAPPNINF *TOPOLOGY on System A.
|
||
|
|
<ul>
|
||
|
|
<li>Type 5 next to System A to display the Display Link Destination Nodes
|
||
|
|
display.
|
||
|
|
<p>The Display Link Destination Nodes display identifies how this
|
||
|
|
node's topology database looks. The link Active Column identifies whether
|
||
|
|
APPN will consider the link in route computation. If a link Active column
|
||
|
|
value is No, this indicates the link will not be included in APPN route selection.</p></li>
|
||
|
|
<li>Next type a 5 to Display Link Characteristics. This information along
|
||
|
|
with the information from the Display Network Attributes (DSPNETA) command
|
||
|
|
identifies the transmission group (TG) values and node values.
|
||
|
|
<p>With this
|
||
|
|
information, you can determine why a path is taken or why one is not being
|
||
|
|
taken for the class of service (COS).</p></li></ul></li>
|
||
|
|
<li>If you type, DSPAPPNINF *LCLNODE on System A,
|
||
|
|
<p>This allows you to determine
|
||
|
|
what locations are known by the local node. It shows locations that are configured
|
||
|
|
on the local node and locations that are found by previous searches.</p></li>
|
||
|
|
<li>If you type, DSPAPPNINF *SSN on System A,
|
||
|
|
<p>This allows you to look at
|
||
|
|
up to 200 endpoint sessions that were successfully established since the last
|
||
|
|
IPL. You can also see the route that was taken by that session, error data,
|
||
|
|
session start BIND, end time, pacing that is used, and others.</p></li>
|
||
|
|
<li>If you type, DSPAPPNINF *SSN SSNTYPE(*INMSSN) on System A,
|
||
|
|
<p>This allows
|
||
|
|
you to determine whether active sessions are routed through the local system.
|
||
|
|
You may, for example, want to vary off a controller, but need to know whether
|
||
|
|
it is being used for intermediate sessions. You can also see which controller
|
||
|
|
descriptions are associated with an intermediate sessions.</p></li></ul>
