Configuring a Primary IP Address for an Interface
Context
Interfaces on
the same industrial switch router can
be assigned IP addresses on overlapping network segments, but the
IP addresses cannot be located on the same network segment. For example,
an interface has been assigned 20.1.1.1/16. If you assign 20.1.1.2/24
to another interface on the same industrial switch router, the system displays
a warning message but the configuration succeeds. If you assign 20.1.1.2/16
to another interface, the system displays an error message, indicating
that the configuration fails because of an IP address conflict.
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The interface view is displayed.
- Run ip address ip-address { mask | mask-length }
A primary IP address is configured for the interface.
By default, no IP address is configured for an interface.
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.
