I decided to use the port of the Catalyst 6509 module 3 and use a Type 5 adapter cable to connect the fast Ethernet ports, namely the 3/15 port of the Catalyst 6509 and the 0/1 port of the Catalyst 3524. Ao mesmo tempo, set the two ports to 100Mbps, full duplex, the same VLAN1 administrative domain and the same VTP domain and the same VTP mode (server mode).
