I&rsquo;ve got <em>debug spanning-tree uplinkfast</em> on to help out.</p> <blockquote> <div class="highlight"><pre tabindex="0" style="color:#f8f8f2;background-color:#282a36;-moz-tab-size:4;-o-tab-size:4;tab-size:4;-webkit-text-size-adjust:none;"><code class="language-fallback" data-lang="fallback"><span style="display:flex;"><span>SW3#sh span | incl 0/2[34] </span></span><span style="display:flex;"><span>Fa0/23 Altn BLK 3019 128.23 P2p </span></span><span style="display:flex;"><span>Fa0/24 Root FWD 3019 128.24 P2p </span></span></code></pre></div></blockquote> <p>Now let&rsquo;s unplug F0/24 and see what happens.</p> https://efb97021.aww-3cz.pages.dev/posts/2010/04/stubby-post-path-cost-of-etherchannels/ Tue, 27 Apr 2010 00:00:00 +0000 https://efb97021.aww-3cz.pages.dev/posts/2010/04/stubby-post-path-cost-of-etherchannels/ <p>I was doing some STP labs tonight and found something that caught me off guard a bit.  I had been meddling with some EtherChannels between a pair of 3750s earlier today, and I forgot to reset the configs before starting on the STP stuff.  One my secondary root switch, I ran a <em>show spanning-tree vlan 1</em> to see what status the ports were in, and I noticed the root path cost.</p>
