Connecting several SG300 for failsafe

[sorensteinmetz]

Not quite sure what will be best practise for me here:

3 x SG300-28

1 x SG300-10MP

Placed in 3 locations

1:

1 x SG300-28

2:

2 x SG300-28

3:

1 x SG300-10MP

I have 4 lines between locations 1 and 2, and 2 lines between locations 2 and 3

My idear was to use the 4 lines from location 1 and split them 2 and 2 on the switches in location 2

Between the two switches on location two I plan on have a 4 port LAG.

The 2 lines from location 3 I planned on split between the two switches on location 2

What I am uncertain about is STP, LAG's  and how to get the best failsafe setup.

Any help would be appreciated greatly.

Looks like I managed to get it working my self.

Used the idear I mentioned and here's the setup:

Location 1:

1xSG300-28

Switch setup with 2 LAG's each including 2 ports

Location 2:

2xSG300-28

Each Switch set up with a 4-port LAG as "stack" between the two.

Each Switch set up with a 2-port LAG connected to the Switch on Location 1

Location 3:

1xSG300-10MP

Switch connected with one line to each of the Switches on location 2

So far the setup is working as a charm.
