When Cisco switch or router port is "connected", it has status "line protocol is up". As far as I know, this applies to all interface types(10BASE-T, 100BASE-TX, 1000BASE-T, 1000BASE-LX10, 1000BASE-SX etc with different transceivers). What is this "line protocol"? I always thought "line protocol" is up once any electrical pulses are detected by Rx. Or is "line protocol" strictly "link integrity test"(LIT) pulses(100-200ns of electrical pulses with 16ms+/-8ms interval)? Any clarification would be much appreciated.
