You can assign at most two IP address to an interface, among which one is the primary IP address and another is secondary IP addresses. A newly specified primary IP address overwrites the previous one if there is any.

The primary and secondary IP addresses of an interface cannot reside on the same network segment; the IP address of a VLAN interface must not be on the same network segment as that of a loopback interface on a device.

A VLAN interface cannot be configured with a secondary IP address if the interface has been configured to obtain an IP address through BOOTP or DHCP.
