Many switches are PHY independent, meaning that a switch could have a mixture of copper, SX, LX, LX10 or other GBIC/SFP modular transceivers. While maintaining the same PHY is the usual approach, it is possible to aggregate a 1000BASE-SX fiber for one link and a 1000BASE-LX (longer, diverse path) for the second link.
Stacking resiliency. Multiple switches can have ways to bypass a “down” switch in a stack, thus allowing the remaining units to function as a stack even with a failed or removed unit. Layer 3 redundancy. Some stackable architectures allow for continued Layer 3 routing if there is a “down” switch in a stack.
The switch forwards all frames received from a private port to the uplink port, regardless of VLAN ID or destination MAC address. Frames received from an uplink port are forwarded in the normal way (i.e. to the port hosting the destination MAC address, or to all ports of the VLAN for broadcast frames or for unknown destination MAC addresses).

In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location.A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room.

A multilayer switch (MLS) is a computer networking device that switches on OSI layer 2 like an ordinary network switch and provides extra functions on higher OSI layers. The MLS was invented [ 1 ] by engineers at Digital Equipment Corporation .
The probability that the path connecting an ingress switch to an egress switch via a particular middle stage switch is free is the probability that both links are free, (1−p) 2. Hence the probability of it being unavailable is 1−(1− p ) 2 = 2 p − p 2 .
