CLIguru-S2 root bridge durumdadır , interface durumlarını da bu cihaz belirler.

 

  1. Root bridge kontrol edelim.

 

Primary root bridge  olarak CLIguru-S1 yapılandıralım , secondary  root bridge olarakda CLIguru-S2 cihazını yapılandıralım.

  1. root bridge olarak CLIguru-S1 yapılandıralım , 2. root bridge olarakda CLIguru-S2 cihazını yapılandıralım.

 

Priority değeri küçük  olanın degeri daha iyidir.
CLIguru-S1 cihazının priority degerini 8192 olarak , CLIguru-S2 cihazının priority degerini ise 4096 olarak değiştirelim.
