<p class="MsoNormal">Hi I am trying to document the spanning tree domain on a brocade environment that has both TurboIron-X24’s and FCX-48G’s<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m traditionally a cisco guy so need some help in figuring out the show output of show span.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Right now we have a mix of rapid spanning tree and classic, I need help in understand which is the mac address of the root bridge, the root ports and the terminology used in the output.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For example – is the root ID a mac address and the vlan ID added in Hex? What is the designated bridge ? is this is the downstream switches bridge ID?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I can’t seem to match the bridge ID and the Root ID to mac address tables on the switch – is anyone able to shed light on these relationships and describe what each of the terms means below?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m guessing the first 4 digits of the DES root and DES Bridge are the priorities in HEX<o:p></o:p></p>
