    Error Message

    Description

    Troubleshooting Method

    Error: The specified IP address is invalid.

    The IP address or subnet mask is incorrect.

    Configure the IP address or subnet mask correctly.

    • The IP address must be a Class A, Class B, or Class C IP address.
    • The subnet mask must match the IP address.

    Error: The specified address conflicts with another address.

    The specified IP address is on the same network segment as the IP address of another interface on the local device.

    Configure another IP address for the interface.

    Error: The specified primary address does not exist.

    The primary IP address to be deleted does not exist.

    NOTE:

    Each interface has only one primary IP address. If you configure multiple primary IP addresses for an interface, the last configured IP address becomes the primary IP address of the interface.

    You do not need to delete the IP address.

    Error: Please configure the primary address in the interface view first.

    The secondary IP address cannot be configured because the primary IP address has not been configured for the interface.

    Configure a primary IP address for the interface first.

    Error: The number of addresses of the specified interface reached the upper limit (31).

    The number of secondary IP addresses on the interface exceeds the maximum; therefore, no more secondary IP address can be configured.

    NOTE:

    Each interface can have a maximum of 31 IP addresses.

    -

    Error: Please delete the sub address in the interface view first.

    The primary IP address cannot be deleted because the interface has secondary IP addresses.

    Delete all the secondary IP addresses from the interface, and then delete the primary IP address.

    Error: The specified address cannot be deleted because it is not the primary address of this interface.

    The command used to delete a primary IP address cannot delete a secondary IP address.

    Run the undo ip address ip-address { mask | mask-length } sub command to delete the secondary IP address.

    Error: The specified sub address does not exist.

    The secondary IP address to be deleted does not exist.

    You do not need to delete the IP address.

    Error: The address already exists.

    The interface has been configured with the same IP address.

    Configure a different IP address for the interface.
