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.

On a Cisco router what does it mean when the status is administratively up but protocol is down?
Ports on Cisco routers can be enabled or disabled by the router OS. "Administratively Up" simply means that the port has been enabled by the router's OS. If a port is enabled (Administratively Up) and the protocol is down, then there is a problem with communications over that port. Problems could one of many including; bad cable on the port, the far end device is down, the protocol configurations on the two connected device ports are not configured correctly to enable communications.
HSRP Configuration Cisco?
Hot standby router protocol. 2 different routers will have 2 different physical addresses, but you can give both of them a shared virtual address. only 1 router will answer on the virtual address at a time, but one goes down the other will take over.
What is the difference in a serial interface with a status of down and a status of administratively down?
Status of "down" means no pc is connected where as "administratively down" depends upon the clock pulse of the interface.
What is the difference in a serial interface with a status of down and a status of administratively?
Status of "down" means no pc is connected where as "administratively down" depends upon the clock pulse of the interface.
What is Clock rate in router?
Data Generating Capability of a Device is called Clock Rate. If the clock rate is high, the processing will be slow down. If the clock rate is low, the processing will be high.
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
What does this mean for a router an interface is up but its line protocol is down disabled?
This may indicate a duplex mismatch between two devices. e.g. a switch and a router. Change both to use auto, instead of hardcoding either half, or full
Which option identifies the primary interface which would be used for initial configuration of a Cisco router?
The primary interface which would be used for initial configuration of a Cisco router exam is 200-120 In this exam you can get all router related details and also about the primary interface usage probelms and there solutions. To get this exam dump visit the link below... dumpspdf.com/200-120.html
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.
Cisco router 2801 serial port is manually down how you can enable this port?
router> enablerouter# configure terminalrouter(config) interface serial (interface number)router(config-if) no shutdownrouter(config-if) endrouter#substitute (interface number) for the actual int number.. eg serial 0/1you can find the number of the interface by using show interfaces from privileged mode
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 would be the path of a packet sent from Router C to Router D if Router A was down?
taka the three routers
