What does administratively down mean?
Administratively down means that the interface has a shutdown command. This router now has two active interfaces with IP addresses. In other lessons, we’ll look at how it can route packets from one interface to another.
What does it mean if the interface is administratively down?
Ethernet0 is administratively down, line protocol is down: This output indicates that a local interface has been manually shut down using the shutdown command.
What do you do for the interface showing administratively down?
You can mark an interface administratively down with the “shutdown” command, and turn it on with the “no shutdown” command. If an interface is shut down, it will display administratively down when using the “show interface” command.
Why does the interface go down after you bring it up?
When you bring the interface up/down you’re merely setting a flag on the driver that the state of the interface is up or down. The NIC is still powered on and can participate in WOL (Wake on LAN) etc.
How do I look at my router settings?
Type ipconfig in the command prompt and press Enter to run the command. Scroll through the information until you see a setting for Default Gateway under Ethernet adapter or Wireless LAN adapter. That’s your router, and the number next to it is your router’s IP address. Close the window when done.
What does UP DOWN mean on a router?
Basically, up/down means the port is available for a cable/connection, but doesn’t have one. Check the cable, or other computer.
How do I enable interface on Cisco router?
To enable an interface, it must be activated using the no shutdown command. (This is similar to powering on the interface.) The interface must also be connected to another device (a hub, a switch, or another router) for the physical layer to be active.
What does link status down mean?
Basically if link-status is up, then you are able to communicate. If link-status is down, then you are unable to communicate.
Why some FastEthernet ports on the switches are up and others are down?
Why are some FastEthernet ports on the switches are up and others are down? The FastEthernet ports are up when cables are connected to the ports unless they were manually shutdown by the administrators. Otherwise, the ports would be down.
What is the reason that the interface status is administratively down line protocol down?
The CLI status output “Serial0/0/0 is administratively down, line protocol is down” means that either the router interface is configured with the “shutdown” interface configuration command or a duplicate IP address exists. If there are duplicate addresses, resolve the conflict by changing one of the IP addresses.
What can cause ” FastEthernet is up, line protocol is down “?
I wonder what can cause that the first line output of the command “show interfaces” will be: “fastEthernet is up, line protocol is down”. Cisco ethernet interfaces are normally down / down if they don’t have a link.
What does ethernet0 down, line protocol down mean?
Ethernet0 is administratively down, line protocol is down: This output indicates that a local interface has been manually shut down using the shutdown command. I configure the interface fa0/0 with IP address and no shut (the cable is not attached to this interface). The interfece goes to up and up state…and after a while to protocol down state.
Why is my Cisco Ethernet up and down?
Cisco ethernet interfaces are normally down / down if they don’t have a link. If you’re seeing up / down, the most likely causes are: is cable that connected to the local interface, but not connected to the far end switch, will cause that situation?
