Usage guidelines
To connect a VLAN to multiple subnets, assign one primary IP address and one secondary IP addresses
to a VLAN interface.
When you configure IP addresses for a VLAN interface, follow these restrictions and guidelines:
•
You can assign a primary IP address to a VLAN interface multiple times. The most recent
configuration takes effect.
•
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 parameters.
•
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.
