Assigning an IP address to an interface

You can assign an interface one primary address and multiple secondary addresses.
Generally, you only need to assign the primary address to an interface. In some cases, you need to
assign secondary IP addresses to the interface. For example, if the interface connects to two subnets, to
enable the device to communicate with all hosts on the LAN, you need to assign a primary IP address
and a secondary IP address to the interface.

Configuration guidelines

Follow these guidelines when you assign an IP address to an interface:
Each interface has only one primary IP address. A newly configured primary IP address overwrites
the previous one.
You cannot assign secondary IP addresses to an interface that obtains an IP address through
BOOTP or DHCP.
The primary and secondary IP addresses you assign to the interface can be located on the same
network segment, but different interfaces on your device must reside on different network segments.
You can manually assign an IP address to an interface, or configure the interface to obtain an IP
address through BOOTP or DHCP. If you change the way an interface obtains an IP address, the
new IP address overwrites the previous one.
The switch supports a 31-bit subnet mask (the mask 255.255.255.254) for saving IP addresses in
the point-to-point communication.

Configuration procedure

To assign an IP address to an interface:
Step
1.
Enter system view.
2.
Enter interface view.
3.
