Right now we are using Cisco 4507R as a core switch and Cisco 3560 using as an access switch in other floor. We configured inter Vlan routing, VTP, port security, Qos, STP, Trunk and Ether channel. Now we perched a Dell6248 switch for redundant of Cisco 4507R switch. Can any one let us know is it possible to connect Dell 6248 with all other Cisco 3560.Can we configure all of thing (inter Vlan routing, VTP, port security, Qos, STP, Trunk and Ether channel) which we configured in Cisco 4507 switch. Would be appreciated if any let us your views. Please have a look attachment for our diagram.
one clarification, I said you need to convert the switches. That's not really what I meant. You need to be aware of the difference between PVST and a single spanning tree. If you have multiple connections to the switches it could cause issues. The safest way would be to run Multiple spanning tree on the Cisco switch. But, there are other options.
