Ho una struttura con diversi 2960 sparsi per l'azienda e sul 4510 li ho tutti configurati in 2 modi ed ho provato su tutti e due le configurazioni.
Alcuni sono configurati in PortChannel (sono switch singoli con 2 porte in fibra) e altri sono configurati con un signolo canale in fibra ridondato però un secondo switch ricollegato al 4510 attraverso un altro canale (mi appoggio perciò allo spanning-tree).
Codice: Seleziona tutto
