SWITCH interface
Three LAN ports of SWITCH interface intended for v3 routers (RJ-45 connectors for con-
necting ethernet devices) act as it is a typical switch device. This means that the router with
internal switch desk reads ethernet frames (a data packets on an ethernet link) from any port
and transmits them on other ports of the switch board. Each port on the switch can transmit
frames independently on every other port.
