Utilizing two physical stacking ports on the back of each switch, a stack can provide for gateway redundancy at Layer 3 and dual-homing redundancy at Layer 2. Only a single uplink is required to provide connectivity to the stack once all stacking cables are installed. Switch stacking allows several switches to be managed as a single, larger switch which can forward traffic over dedicated stack links rather than front-side network links. In some cases, power redundancy. Yes. Now you wonder what are these access layer switches? thatActually, there are three types of switches in a LAN. Any suggestions? Perhaps break it up into. When people search for stackable UniFi switches, what they often want is the simplicity and efficiency of managing multiple switches as one. UniFi gear doesn't support that yet.
