ATM 0 is down, line protocol is down • The ATM interface has been disabled with the shutdown command. or • The ATM line is down, possibly because the ADSL cable is disconnected or because the wrong type of cable is connected to the ATM port. ATM 0.n is up, line protocol is up The specified ATM subinterface is up and operating correctly. ATM 0.n is administratively down, line protocol The specified ATM subinterface has been disabled is down with the shutdown command. ATM 0.n is down, line protocol is down The specified ATM subinterface is down, possibly because the ATM line has been disconnected (by the service provider). For Fast Ethernet Interfaces Fast Ethernet n is up, line protocol is up The specified Fast Ethernet interface is connected to the network and operating correctly. Fast Ethernet n is up, line protocol is down The specified Fast Ethernet interface has been correctly configured and enabled, but the Ethernet cable might be disconnected from the LAN. 14-4 Cisco 850 Series and Cisco 870 Series Access Routers Software Configuration Guide OL-5332-01

Output
Cause
For ATM Interfaces
ATM 0 is up, line protocol is up
The ATM line is up and operating correctly.
ATM 0 is down, line protocol is down
•
The ATM interface has been disabled with the
shutdown
command.
or
•
The ATM line is down, possibly because the
ADSL cable is disconnected or because the
wrong type of cable is connected to the ATM
port.
ATM 0.
n
is up, line protocol is up
The specified ATM subinterface is up and operating
correctly.
ATM 0.
n
is administratively down, line protocol
is down
The specified ATM subinterface has been disabled
with the
shutdown
command.
ATM 0.
n
is down, line protocol is down
The specified ATM subinterface is down, possibly
because the ATM line has been disconnected (by the
service provider).
For Fast Ethernet Interfaces
Fast Ethernet
n
is up, line protocol is up
The specified Fast Ethernet interface is connected to
the network and operating correctly.
Fast Ethernet
n
is up, line protocol is down
The specified Fast Ethernet interface has been
correctly configured and enabled, but the Ethernet
cable might be disconnected from the LAN.
