This command has no default configuration.
Command Mode
Interface Configuration (VLAN, Loopback) mode
User Guidelines
This command also implicitly enab les the VLAN or loopback interface fo r
routing (i.e. as if the user had issued the ‘routing’ interface command). By
default, configuring an IP address on a VLAN enables in-band management
for interfaces configured with that VLAN. Setting up an IP address on VLAN
1 enables switch management on all in-band interfaces except for those where
VLAN 1 is specifically excluded.
Example
The following example defines the IP address and subnet mask for VLAN 15
and enables the VLAN for routing.
console(config)#interface vlan 15
console(config-if-vlan15)#ip address 192.168.10.10
255.255.255.0
