I have customer that requires that we keep their current 2950 series switches in place in their network and still maintain a vlan in a box design similar to a switch stack. Basically what they want to do is configure 5x2950s per stack and lace them up using 10/100 ports on the last 2 ports of the switch.
The connectivity would look like the following:
sw5 would connect back to sw1 to complete the loop
RSTP would handle the loop control for each stack.
We are proposing running a common VLAN across the 5 switch stack and then uplink the sw1 and sw5 switches into a pair of 3750 switches running HSRP on the VLAN and L3 to the core.
We would also be using an RPS to protect each switch from power supply failure. That RPS would be wired into a seperate power system from the switch stack themselves.
This is an old school design but it should still work.
Any thoughts or concerns? I would like some feedback.
