Parameters
ip-address: Specifies an IP address in dotted decimal notation.
mask: Specifies a subnet mask in dotted decimal notation.
mask-length: Sets the number of consecutive 1s in the subnet mask in the range of 0 to 32.
sub: Indicates the address is a secondary IP address.
Usage guidelines
To connect a VLAN to multiple subnets, assign one primary IP address and multiple secondary IP
addresses to a VLAN-interface.
When you configure IP addresses for a VLAN-interface, follow these rules:
• The primary IP address you assign to a VLAN-interface overwrites the previous one, if any.
• Remove all secondary IP addresses before you remove the primary IP address.
• To remove all IP addresses, use the undo ip address command without any parameter.
• To remove the primary IP address, use the undo ip address ip-address { mask | mask-length }
command.
• To remove a secondary IP address, use the undo ip address ip-address { mask | mask-length } sub
command.
Examples
# Specify the IP address as 1.1.0.1, the subnet mask as 255.255.255.0 for VLAN-interface 1.
<Sysname> system-view
[Sysname] interface vlan-interface 1
[Sysname-Vlan-interface1] ip address 1.1.0.1 255.255.255.0
