I am wondering how to achieve switch redundancy. I have a pair of Cat3550 switches and 15 cat 2950T switches. I wanted to setup a cluster where two Cat3550 are primary switches and two cat 2950T are backup switches. I wanted to know, how to setup redundancy so that when the 3550 switches fail the 2950 can take over.
You would have to elaborate more on your setup , 3550's are a layer2/3 switch where a 2950 is layer 2 only . Your best bet would be to make the 3550's the core switches and then connect your 2950's between each and use HSRP as your backup . Very unlikely you would ever lose both 3550's at the same time .
Agreed on Glen that you can connect two 3550 together as core. Each 2950 use dual uplinks to the 3550. Connect the shared device and servers to 3550 or one of the 2950, it depends on the available port and location. Users connect to 2950.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
