Cisco CLI Error: % Invalid input detected at ‘^’ marker
This message is not restricted to a particular CLI Mode or to a particular CLI command or task.
What does this error mean?
This error indicates that we have made an error while typing in a CLI command. This error message is preceded by a line with the single character ‘^’. There may be multiple errors in a line that we have typed in at the CLI. The ‘^’ indicates the first instance of an error in the line typed in.
For example, suppose we were attempting to configure an IP address on a router interface. We attempt to configure it as follows:
Looking at the command that we have typed in, we can see that we have misspelled the word «address». The ‘^’ under the letter ‘r’ in the word «address» informs us that there is an error at the letter ‘r’.
We can correct the error and type in the command again.
We have corrected the error in the word «address» but we notice that there is another error message. This time we notice that the ip address that we are trying to configure has an extra ‘.’ at the end. The ‘^’ indicates that there is an error at this location in the line that we have typed in.
We will re-enter the command without the extra ‘.’
This time the command is accepted with no warnings or error messages.
Point to note: There may be multiple errors in a line, but the ‘^’ character appears underneath the first error that is found. All of the errors are not highlighted at the same time.
A common occurence of this error with the «show» command
Take a look at the following example:
We are attempting to run the «show running-config» command. Why do we see an error message instead of the desired output?
Upon further inspection, we realize that we are currently in Global Configuration Mode (as indicated by the word ‘config’ in the CLI prompt). Most of the «show» commands are available in Privileged EXEC Mode (although a large number of them are also available in User EXEC Mode).
In this instance, if we want to see the running configration, we would need to either precede the command with the word «do», or exit back into Privileged EXEC Mode and run the «show run» command.
If we run into an «Invalid input detected at ‘^’ marker» error while attempting to run a «show» command we should always check to confirm that we are not in a Configuration Mode.
Remember : The «show running-config» and «show startup-config» commands are only available in Privileged EXEC Mode — they are not available in User EXEC Mode!
Other common occurences of this error
Interface command
If you run into this error while trying to enter the Interface Specific Configuraiton Mode using the interface command, it is possible that the interface label has been incorrectly typed in.
In the following example, the switch only has 26 gigabitethernet interfaces (0/1 to 0/26). We are attempting to configure interface gi 0/27. The ‘^’ character indicates that 0/27 is not a valid interface label.
In the following example, we are attempting to configure interface gigabitethernet 3/10 on a switch stack. The stack only consists of 2 physical switches — the range of valid interfaces for the stack is 0/1 — 0/26 and 1/1 — 1/26. Interface gigabitethernet 3/10 is not a valid interface for this switch stack.
Ip address command
If you run into this error while trying to configure an IP address on an interface, make a note of where the ‘^’ character appears. In the following example, the ‘^’ character appears at the beginning of the word «address».
The position of the ‘^’ character seems to indicate that the word address is not a valid keyword or parameter in the current command context. We confirm this by entering ‘?’ after the first word of the command as follows:
| . | . <output truncated> |
| arp | Configure ARP features |
| dhcp | Configure DHCP parameters for this interface |
| . | . <output truncated> |
The context sensitive help indicates that the ip address command is not a valid command in the current context. What could be the reason for this? The most likely reason is that we are on a Layer 2 switch attempting to configure an IP address on a Layer 2 interface. IP addresses can only be configured on Layer 3 interfaces.

i don’t know why it did not recognize this command, any helps? pls.

See what that gives you. If the option of address is not in the list then you will need to configure an SVI (or sub-interface if you will), which goes like this:

It should be: ip address <ip> <mask>
PS. IP address, must be configured on vlan interface.

Use the «?». It is pretty helpful with these commands.

DanA is right. the command is «ip address», and when in doubt, use «?». It ALWAYS comes in handy, even on the CCNA exam.

You might want to try playing around with this to help you get more comfortable with the CLI.
Think of it from the point of view of the device, you are being quite ambiguous.
IP what? route, address, etc.
first of all thx for your replies,
i do configure a VLAN interface (and it works) but what i need is to set ASA’s interfaces addresses, for exemple when i use «show running-config interface» it gives me :
how to set the interface ip?

It’s a switch so you have to write
However, for me «no switchport» is not working and it’s giving an invalid input at marker.

The main error messages in CLI
The error message “% Ambiguous command.” is displayed if the command cannot be uniquely identified. If you enter the command in an abbreviated form, you must enter it to the point where it is uniquely identified.
The following is an example of a “% Ambiguous command.” error message
In this example, you would type “conf t” to enter global configuration mode, but you would type “con t” to enter global configuration mode. There are multiple commands that start with “con” and they cannot be uniquely identified. In such cases, the “% Ambiguous command.” will displayed
% Incomplete command.
The error message “% Incomplete command.” appears if you do not specify the required parameters for the command you entered. Make sure you know which parameters to provide.
