Command Manual – IP Address and Performance
H3C S3610&S5510 Series Ethernet Switches
Description
Use the ip address command to assign an IP address and mask to the interface.
Use the undo ip address command to remove all IP addresses.
Use the undo ip address [ ip-address { mask | mask-length } ] command to remove the
IP address.
By default, no IP address is assigned to any interface.
The relationship between the primary address and the secondary addresses is as
follows:
When you configure a primary IP address for an interface that already has a
primary IP address, the new address will replace the old one.
The primary and secondary IP addresses can belong to the same network
segment.
Before deleting the primary IP address, you must delete all the corresponding
secondary IP addresses first.
Note that:
If you execute the undo ip address command without any parameter, the switch
deletes all IP addresses of the interface.
The undo ip address ip-address { mask | mask-length } command is used to delete
the primary IP address.
The undo ip address ip-address { mask | mask-length } sub command is used to
delete a specified secondary IP address.
If you configure an interface to obtain an IP address through BOOTP, DHCP, you
cannot configure secondary IP addresses for this interface.
Related command: display ip interface.
Note:
You can configure IP addresses for VLAN interface, Tunnel interface and Loopback
interface on S3610&S5510 Series Ethernet Switches.
Example
# Assign VLAN interface 1 a primary IP address and a secondary IP address, with
subnet masks being 255.255.255.0.
