问题
An administrator issues the show ip interface s0/0 command and the output displays that interface Serial0/0 is up, line protocol is up.
What does "line protocol is up" specifically indicate about the interface?
选项
A、The cable is attached properly.
B、CDP has discovered the connected device.
C、Keepalives are being received on the interface.
D、A carrier detect signal has been received from the connected device.
E、IP is correctly configured on the interface.
答案
C
解析
Explanation:
Serial 0/0 is up, line protocol is up is the proper status line condition.
Line serial0/0 is up: This statement represents that the physical connection is good.
Line protocol is up: This represents that the data link layer is OK, meaning that layer 2 keepalives are being received on the interface.
When the line protocol goes down, a possible problem is keep-alives not being sent by remote router.
