Description
Use the ip address command to assign an IP address and subnet mask to a VLAN interface.
Use the undo ip address command to remove the IP address and subnet mask for a VLAN interface.
By default, no IP address is assigned to any VLAN interface.
In general conditions, you need to assign only one IP address for a VLAN interface. For a VLAN to
connect to multiple subnets, On an S7500E series Ethernet switch, you can assign up to eight IP
addresses to a VLAN interface. Among these IP addresses, one is primary and the others are
secondary.
When configuring IP addresses for a VLAN interface, consider the following:
The primary IP address you assign to a VLAN interface overwrites the previous one, if any.
Before removing the primary IP address, remove all secondary IP addresses.
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.
