I have network design like at above picture. There are 3 floors and each one is stapled by one switch. All 3 floors are connected to the MAIN Switch which is connected to the Edge router`s interrior switch only by one cat. 5e cable. That means that 3 floors use only one 1GB Ethernet connection.
I have 2 spare cables which I would like to use to provide better communication accross my network. The plan is to connect each floor by separate cable (3 x 1 GB) within one address network range - 192.168.1.0/24 because there are no VLAN`s.
I can`t connect all 3 cables just like that because of Spanning Tree and frame storm when multiple connections between single switch.
CloudCore has interior switch stapled into one bridge. HP switches has one single switch with default VLAN.
What would be the best practice and how can I force MikroTik CloudCore and HP MAIN Switch to use all 3 cables (one cable should carry all traffic from single floor) ad the same time ?
