Displaying Ip Addressing Configuration; Vlan Interface Ip Address Configuration Examples; Ip Address Configuration Example - H3C S5100-SI Operation Manual

You may assign an interface multiple IP addresses, one primary and multiple secondaries, to connect
multiple logical subnets on the same physical subnet.
Follow these steps to configure an IP address for an interface:
To do...
Enter system view
Enter interface view
Assign an IP address to the
Interface
You can assign at most two IP addresses to an interface of the S5100-SI Series Ethernet Switches,
one of which is the primary IP address and the other is the secondary IP address. The primary and
secondary IP addresses of an interface cannot reside on the same network segment. 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.
The S5100-EI series Ethernet switches do not support to specify a secondary IP address of an
interface.
A newly specified primary IP address overwrites the previous one if there is any.
