I have an issue on my network.Find attached the network diagram.
Three different providers are connected to a plain switch.The three different providers in turn provide point to point connectivity to all the terminals in different locations.
The issue at hand now,is that the if one Provider is up the other providers will be down,as all the terminals and providers are on the same LAN,i.e the same network.
I got to know HWIC-4ESW or HWIC-D-9ESW ,but i dont know if it is going to solve my problem and i dont know how to configure it.And if am going to configure should i create a VLAN or should i just put all the different providers on different ports.
What is the advanatge and disadvantage of VLAN.
What do is tand to gain if i onfigure HWIC-4ESW or HWIC-D-9ESW and put the different providers on differnt ports.
What is the advantage of configuring HWIC-4ESW or HWIC-D-9ESW on a router over using a layer 3 switch like 3560
I WILL BE EXPECTING YOUR DETAILED REPLY
