Notes:
Ethernet up means that layer 1 is hearing carrier
detect on the interface. Line protocol is up
means that the interface is hearing keepalives every 10
seconds ( line 10). Obviously if layer 1 is down then laer 2 will
be down as well..
Layer 1 down - no physical connection or connectied to a dead
circuit; or the interface on the other end is in a shutdown state
Layer 1 shutdown locally = administratively down
Layer 2 down because of layer 1 down; no DCE on a serial
link, 2 DCE’s; clockrate not set, or incompatible
