What is the most likely cause for the line protocol being down?
The most likely cause for any type of line protocol being down is that a network administrator used the shutdown command on these lines to prohibit access to telnet, ssh and connection to the line con 0.
Which command output would you most likely see if you had a problem at the physical layer?
Ethernet 0/0 is down, line protocol is down
How do you change line protocol from down to up?
To change the line protocol from down to up, first ensure that the physical connection is intact and that the interface is enabled. You can do this by accessing the device's configuration mode (e.g., using a command-line interface) and issuing the command to enable the interface, such as no shutdown on Cisco devices. Additionally, check for any misconfigurations, link issues, or hardware failures that may be affecting the connection. Once these issues are resolved, the line protocol should come up.
What is line protocol is administratively down on a cisco router?
The message is something like "Serial 0/0 is up, line protocol is down". The first part refers to the physical connection (layer 1 of the OSI model), which works in this case; the second part refers to layer 2 of the OSI model (the serial networking protocol, like HDLC or PPP), which in this example doesn't work for some reason.
What is Serial line interface protocol?
It is a very simple protocol used for transmission of IP datagrams across a serial line.
If you encounter a line protocol down message on a router interface what is is an indication of?
There is a problem with the interface at the data-link layer that prevents it from functioning properly
Which command output would you most likely see if you had a problem at the data link layer?
Serial 0/1 is up, line protocol is down
Full form of SLIP in computers?
Serial link internet protocol..............
Which problem is evident if the show ip interface command shows that the interface is down and the line protocol is down?
If the show ip interface command indicates that the interface is down and the line protocol is down, it typically suggests a physical layer issue. This could be due to a disconnected cable, a malfunctioning network interface card, or a disabled interface. Additionally, it may indicate that the interface has not been administratively enabled using the no shutdown command. Troubleshooting should focus on checking physical connections and the interface configuration.
What is line protocol?
The rules for exchanging data between computers
How data travel through telephone line connection?
DATA Transmission is done through SLIP (Serial Line Internet Protocol) & PPP (Point to Point Protocol) Protocols to enable computers to interact with Internet over Telephone Line.
What are the Network operating system covered?
IP, Enhanced Interior Gateway Routing Protocol (EIGRP), Serial Line Interface Protocol Frame Relay, Routing Information Protocol Version 2 (RIPv2),VLANs, Ethernet, access control lists (ACLs).
