After doing some studies, I came to the conclusion that a number of mac addresses were being removed from the mac address database at an excessively rapid rate: mac address table location: 00:26:9e:3c:7e:6a c3750g-48t-st#show mac-address-table address \u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014- types of ports for vlan mac addresses The address is 1 0026.9e3c.7e6a. \u2014\u2014\u2014\u2014\u2014\u2014 \u2014\u2014\u2014\u2014 \u2014\u2014- Mac addresses that are dynamic and total for this requirement are as follows: 1 and after about ten to twenty seconds have passed: mac address table location: 00:26:9e:3c:7e:6a c3750g-48t-st#show mac-address-table address \u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014- types of ports for vlan mac addresses \u2014\u2014\u2014\u2014\u2014\u2014 \u2014\u2014\u2014\u2014 \u2014\u2014\u2014\u2014 In the past, The aging time is the one that is set by default for c3750g-48t-st#: c3750g-48t-st#show mac-address-table aging-time vlan to display data The global aging time is equal to 300 vlan aging time. I am \u2014\u2014\u2014\u2014\u2014\u2014\u2014- 1 300 Considering that the topology does not change all that often, it does not seem to be an issue of spanning tree complexity: c3750g-48t-st#show spanning-tree vlan was specified. 1 particulars include the fact that the topological change flag was not set, the detected flag was not set, and the total number of topology changes was 313; the most recent change came from port-channel at 13:42:30. This is the first time: hold 1, topology change 35, notification 2 timers: hello 0, topology change 0, notification 0, aging 300 ws-c3750v2-48ps-s","og_url":"https:\/\/myblogd.com\/index.php\/2024\/10\/01\/there-was-a-problem-with-flooding-on-the-3750g\/","og_site_name":"myBlogd - Free Publishing and Advertising","article_published_time":"2024-10-01T22:04:00+00:00","author":"Unic0rn","twitter_card":"summary_large_image","twitter_misc":{"Written by":"Unic0rn","Est. reading time":"2 minutes"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"Article","@id":"https:\/\/myblogd.com\/index.php\/2024\/10\/01\/there-was-a-problem-with-flooding-on-the-3750g\/#article","isPartOf":{"@id":"https:\/\/myblogd.com\/index.php\/2024\/10\/01\/there-was-a-problem-with-flooding-on-the-3750g\/"},"author":{"name":"Unic0rn","@id":"https:\/\/myblogd.com\/#\/schema\/person\/96c9aef261d552382f4f8f437710eb86"},"headline":"THERE WAS A PROBLEM WITH FLOODING ON THE 3750G.","datePublished":"2024-10-01T22:04:00+00:00","mainEntityOfPage":{"@id":"https:\/\/myblogd.com\/index.php\/2024\/10\/01\/there-was-a-problem-with-flooding-on-the-3750g\/"},"wordCount":339,"commentCount":0,"keywords":["Camping"],"articleSection":["Camping"],"inLanguage":"en-US","potentialAction":[{"@type":"CommentAction","name":"Comment","target":["https:\/\/myblogd.com\/index.php\/2024\/10\/01\/there-was-a-problem-with-flooding-on-the-3750g\/#respond"]}]},{"@type":"WebPage","@id":"https:\/\/myblogd.com\/index.php\/2024\/10\/01\/there-was-a-problem-with-flooding-on-the-3750g\/","url":"https:\/\/myblogd.com\/index.php\/2024\/10\/01\/there-was-a-problem-with-flooding-on-the-3750g\/","name":"THERE WAS A PROBLEM WITH FLOODING ON THE 3750G. - myBlogd - Free Publishing and Advertising","isPartOf":{"@id":"https:\/\/myblogd.com\/#website"},"datePublished":"2024-10-01T22:04:00+00:00","author":{"@id":"https:\/\/myblogd.com\/#\/schema\/person\/96c9aef261d552382f4f8f437710eb86"},"breadcrumb":{"@id":"https:\/\/myblogd.com\/index.php\/2024\/10\/01\/there-was-a-problem-with-flooding-on-the-3750g\/#breadcrumb"},"inLanguage":"en-US","potentialAction":[{"@type":"ReadAction","target":["https:\/\/myblogd.com\/index.php\/2024\/10\/01\/there-was-a-problem-with-flooding-on-the-3750g\/"]}]},{"@type":"BreadcrumbList","@id":"https:\/\/myblogd.com\/index.php\/2024\/10\/01\/there-was-a-problem-with-flooding-on-the-3750g\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https:\/\/myblogd.com\/"},{"@type":"ListItem","position":2,"name":"THERE WAS A PROBLEM WITH FLOODING ON THE 3750G."}]},{"@type":"WebSite","@id":"https:\/\/myblogd.com\/#website","url":"https:\/\/myblogd.com\/","name":"myBlogd - Free Publishing and Advertising","description":"Free Publishing and Advertising","potentialAction":[{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https:\/\/myblogd.com\/?s={search_term_string}"},"query-input":{"@type":"PropertyValueSpecification","valueRequired":true,"valueName":"search_term_string"}}],"inLanguage":"en-US"},{"@type":"Person","@id":"https:\/\/myblogd.com\/#\/schema\/person\/96c9aef261d552382f4f8f437710eb86","name":"Unic0rn","image":{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/secure.gravatar.com\/avatar\/d44be44ba494c1405c9fa916c96bedf5aba1ff6c125ad64d9261ab4d60ba9aed?s=96&d=wavatar&r=g","url":"https:\/\/secure.gravatar.com\/avatar\/d44be44ba494c1405c9fa916c96bedf5aba1ff6c125ad64d9261ab4d60ba9aed?s=96&d=wavatar&r=g","contentUrl":"https:\/\/secure.gravatar.com\/avatar\/d44be44ba494c1405c9fa916c96bedf5aba1ff6c125ad64d9261ab4d60ba9aed?s=96&d=wavatar&r=g","caption":"Unic0rn"},"sameAs":["https:\/\/myblogd.com"],"url":"https:\/\/myblogd.com\/index.php\/author\/unic0rn\/"}]}},"_links":{"self":[{"href":"https:\/\/myblogd.com\/index.php\/wp-json\/wp\/v2\/posts\/11169","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/myblogd.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/myblogd.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/myblogd.com\/index.php\/wp-json\/wp\/v2\/users\/23"}],"replies":[{"embeddable":true,"href":"https:\/\/myblogd.com\/index.php\/wp-json\/wp\/v2\/comments?post=11169"}],"version-history":[{"count":1,"href":"https:\/\/myblogd.com\/index.php\/wp-json\/wp\/v2\/posts\/11169\/revisions"}],"predecessor-version":[{"id":33151,"href":"https:\/\/myblogd.com\/index.php\/wp-json\/wp\/v2\/posts\/11169\/revisions\/33151"}],"wp:attachment":[{"href":"https:\/\/myblogd.com\/index.php\/wp-json\/wp\/v2\/media?parent=11169"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/myblogd.com\/index.php\/wp-json\/wp\/v2\/categories?post=11169"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/myblogd.com\/index.php\/wp-json\/wp\/v2\/tags?post=11169"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
