Assigning an IP Address to a VLANIF Interface
As a VLANIF interface is a Layer 3 logical interface, it can communicate with other interfaces at the network layer only after being assigned an IP address.
Procedure
- Run system-view
The system view is displayed.
- Run interface vlanif vlan-id
The VLANIF interface view is displayed.
The VLAN ID specified in this command must be the ID of an existing VLAN.
- Run ip address ip-address { mask | mask-length } [ sub ]
An IP address is assigned to the VLANIF interface for communication at the network layer.
If IP addresses assigned to VLANIF interfaces on a Layer 3 device belong to different network segments, a routing protocol must be configured on the Layer 3 switch to provide reachable routes. Otherwise, VLANIF interfaces cannot communicate with each other at the network layer. For configurations of routing protocols, see the NetEngine 8000 F Configuration Guide - IP Routing.
- Run commit
The configuration is committed.
Follow-up Procedure
To disable all users in a VLAN from communicating with users in other VLANs through a VLANIF interface, whereas communication is available between users within the VLAN, run the shutdown command in the VLANIF interface view.
Both Layer 2 and Layer 3 traffic is transmitted over the VLANIF interface. Running the shutdown command in the VLANIF interface view prohibits only Layer 3 traffic. After running the display interface vlanif command, you can view that traffic statistics still increase on this VLANIF interface.
To prohibit all traffic on the VLANIF interface, run the shutdown vlan command in the VLANIF interface view.
