<div><p>This is not an all-inclusive discussion of how to read your trace
|
|
output. However, it does highlight the key events to look for in the trace
|
|
information.</p>
|
|
<p>In an <em>integrated services policy</em>, the most important event to pay
|
|
attention to is whether the ReSerVation Protocol (RSVP) connection was rejected
|
|
because a policy for that connection was not found. Here is an example of
|
|
a successful message:</p>
|
|
<p><samp class="codeph">12/15 11:36:14 [336,80] TRCE :.......rpapi_getPolicyData: Found
|
|
action name vreStnl_kraMoNlCvreStnl for flow[sess=x.x.x.x:y:z:s, source=x.x.x.x:y]</samp></p>
|
|
<p>Here is an example of an unsuccessful integrated services connection message:</p>
|
|
<p><samp class="codeph">12/15 11:36:14 [336,80] TRCE :.......rpapi_getPolicyData: Unable
|
|
to find action name for flow [sess=x.x.x.x:y]</samp></p>
|
|
<p>For a <em>differentiated services policy</em>, the most important messages
|
|
show if the server loaded a policy rule or if an error occurred
|
|
in the policy configuration file.</p>
|
|
<pre>Example:
|
|
01/11 14:07:52 [376,57] TRCE :......KernelAddPolicyRule: Installing rule = timed_42ring.
|
|
01/11 14:07:52 [376,57] EVNT :.......create_tcp_resv: No value in config file for
|
|
DiffServInProfilePeakRate, defaulted to 100000 00.
|
|
01/11 14:07:52 [376,57] TRCE :.......create_tcp_resv: Create resv - bRate: 537395 5722SS1 V5R1M0

|
|
<p>You can also have messages showing that the tags in the policy configuration
|
|
file were incorrect. Here are some sample messages:</p>
|
|
<pre>12/15 11:36:14 [336,80] TRCE :.......rpapi_getPolicyData: Unknown attribute %s in ServicePolicy-Ignoring.
|
|
12/15 11:36:14 [336,80] TRCE :.......rpapi_getPolicyData: Unknown attribute %s in Priority
|
|
Mapping-Ignoring.</pre>
