I've been recently working on installing some 10 gigabit networking in my home using two MikroTik switches, and I'm wondering if I can get these to use the pre-existing 1 Gbps Cat5e lines for failover purposes in case the 10 gigabit fiber link goes down.
The original backbone of my home LAN is a series of unmanaged gigabit switches connected with Cat5e. The internet router connects to Unmanaged C. Unmanaged B is where my FreeNAS and unRAID servers are.
My 10 gigabit upgrade consists of:
1) Replacing Unmanaged C with a MikroTik CSS326-24G-2S+RM.
2) Adding a MikroTik CRS305-1G-4S+in to the server closet, with its one RJ45 port connected to Unmanaged B.
3) A new fiber optic cable between the two new MikroTik switches.
Obviously this creates a loop. I am thinking about disabling via the web GUI the port on MikroTik CSS326-24G-2S+RM that connects to Unmanaged A. I can log in remotely to re-enable this port if I notice the 10G fiber connection go down. The question is, can the switch automate this failover process, and enable a specific RJ45 port if one of the SFP+ ports goes down, then bring down the RJ45 port if the SFP+ comes back?
