Multiple domains fully illustrate that Cat-3 is the root bridge:
The root ports are port 1/0. Note that the catalyst 4000s,5000s,6000s is not labeled as a 1/0 physical port, and the NPM software uses a reference to the logical control port, SC0, as a "logical root port".
Local bid and Root bridge bid match.
Root Path Cost is 0.
Timer value matches.
All ports are in the forwarding state.
Look for the end--the root br

Method Two, under Windows to build a bat file, the contents and you telnet to the switch to modify the command used when the same, but the
Using the DEBUG command can help us ts, but using the DEBUG command will usually output a lot of information, many of which are unnecessary and cause high CPU load, in this case, we can limit the debug output.You can apply the ACL to debug to limit that only the required debug information is output.For example, to view only ICMP packets from 1.1.1.1 to 1.1.1.2:Router (config) # access-list 100 permit ICMP H
