26.10.2 Configuring VLAN as Layer 3 Interfaces

Points to note

VLANs can be used as Layer 3 interfaces by setting an IP address. Various Layer 3 functionality settings can be performed by the interface vlan command and in the VLAN interface configuration mode.

The following describes an example of setting an IPv4 address for a VLAN interface. For details about the Layer 3 functionality that can be set for a VLAN interface, see the chapter for the respective functionality used.

Command examples

   Switches to the VLAN interface configuration mode for VLAN 10. If the VLAN ID specified for the interface vlan command is not yet set, a port VLAN is automatically created and set using the vlan command.

2. (config-if)# ip address 192.168.1.1 255.255.255.0

   Sets the IPv4 address 192.168.1.1 and the subnet mask 255.255.255.0 for VLAN 10.
