Cisco IOS-XE router high memory utilization - Connect IT Community | Kaseya
<main> <article class="userContent"> <p><strong>PROBLEM:</strong></p> <p>I am observing incorrect memory utilization within Traverse for my Cisco IOS-XE router.</p> <p> </p> <p><strong>CAUSE:</strong></p> <p>It is observed that Cisco IOS-XE routers may be reporting incorrect memory utilization on OID '.1.3.6.1.4.1.9.9.109.1.1.1.1.12' (cpmCPUMemoryUsed) due to Cisco bug #CSCuc40262.</p> <p> </p> <p><strong>WORKAROUND:</strong></p> <p> It is recommended that if high memory utilization is observed when it should not, to update the OID to use '.1.3.6.1.4.1.9.9.109.1.1.1.1.27' (cpmCPUMemoryCommitted) instead.</p> <p>To update the OID to use cpmCPUMemoryCommitted, please review the following steps:</p> <ol><ol><li> Copy and paste the OID property from the test configuration page into a text editor, it should look something like:<br>.1.3.6.1.4.1.9.9.109.1.1.1.1.12.7, where the last digit ('7' in this case) is the index of the entity.<br><img src="https://us.v-cdn.net/6032361/uploads/migrated/Q59A5NA2YD5F/oid.png" alt="oid.png" class="embedImage-img importedEmbed-img"></img><br><br></li> <li>Validate the device reports/exposes a value for cpmCPUMemoryCommitted and that it corresponds to the same entity (index):<br>- Open a command prompt on the DGE(or -X) directly monitoring the device<br>- Run (assumes SNMPv2):<br>snmpwalk -Oefqnt -v 2c -c <em><strong>XYZ n.n.n.n</strong></em> .1.3.6.1.4.1.9.9.109.1.1.1.1.27<br>where <strong><em>XYZ</em> </strong>is the community string and <strong><em>n.n.n.n</em></strong> is the IP/host address<br><br></li> <li> You should get an output like:<br>.1.3.6.1.4.1.9.9.109.1.1.1.1.27.7 1741532, where the first column is the exact OID path and the second column being the value of cpmCPUMemoryCommitted for index '7'.<br><img src="https://us.v-cdn.net/6032361/uploads/migrated/NTTDOKRY6IZ1/walk.png" alt="walk.png" class="embedImage-img importedEmbed-img"></img></li> </ol></ol><p>Note: We are reviewing the information further to determine if a separate signature or test should be included specifically for this case.</p> <p><strong>APPLIES TO:</strong></p> <p>All versions of Traverse </p> <p> </p> <p><strong>REFERENCE:</strong></p> <p>This issue is discussed in the following thread:<br><a href="/home/leaving?allowTrusted=1&target=https%3A%2F%2Fsupportforums.cisco.com%2Fdiscussion%2F12604766%2Flsmpiio-pool-low-memory-cisco-isr-4321">https://supportforums.cisco.com/discussion/12604766/lsmpiio-pool-low-memory-cisco-isr-4321</a></p> <p> </p> </article> </main>
