Configuring an mVLAN

Configuring an mVLAN

Context

Management VLAN (mVLAN) allows you to use the VLANIF interface of the mVLAN to log in to the management industrial switch router to manage devices in a centralized manner.

To use a remote network management system (NMS) to manage devices in a centralized manner, configure a management IP address on the device. You can then log in to the device in Telnet mode and manage the device by using the management IP address. The management IP address can be configured on a management interface or VLANIF interface. If a user-side interface is added to the VLAN, users connected to the interface can also log in to the device. This brings security risks to the device.

After a VLAN is configured as an mVLAN, no access interface or Dot1q tunnel interface can be added to the VLAN. Access and Dot1q tunnel interfaces are often connected to users. When these interfaces are prevented from joining the mVLAN, users connected to the interfaces cannot log in to the device, improving device security.

Generally, a VLANIF interface needs to be configured with only one management IP addresses. In specified scenarios, for example, users in the same mVLAN belong to multiple different network segments, you need to configure a primary management IP address and multiple secondary management IP addresses.

You can only log in to the local device using the management interface, whereas you can log in to both local and remote devices using a VLANIF interface of an mVLAN. When logging in to the remote device using the VLANIF interface of an mVLAN, you need to configure VLANIF interfaces on both local and remote devices and assign IP addresses on the same network segment to them.

Pre-configuration Tasks

Before configuring an mVLAN, complete the following task:

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    vlan vlan-id

    The VLAN view is displayed.

  3. Run:

    management-vlan

    The VLAN is configured as the mVLAN.

    VLAN 1 cannot be configured as the mVLAN.

  4. Run:

    quit

    Exit from the VLAN view.

  5. Run:

    interface vlanif vlan-id

    A VLANIF interface is created and its view is displayed.

  6. Run:

    ip address ip-address { mask | mask-length } [ sub ]

    An IP address is assigned to the VLANIF interface.

Checking the Configuration

  • Run the display vlan command to check the mVLAN configuration. In the command output, the VLAN marked with a * is the mVLAN.
