Configuration guidelines

Follow these guidelines when you assign an IP address to an interface:

• An interface can have 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, DHCP, PPP address negotiation, or IP unnumbered.

• The primary and secondary IP addresses assigned to the interface can be located on the same network segment. Different interfaces on your device must reside on different network segments.
