Management VLAN

Management VLAN

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 use the management IP address to log in to the device using STelnet and manage the device. If a user-side interface is added to the VLAN corresponding to the management IP address, users connected to the interface can also log in to the device. This poses security risks to the device.

To enhance security, you can configure the VLAN as the management VLAN (mVLAN). Access or Dot1q tunnel interfaces cannot be added to the mVLAN. (The VLANs not specified as the mVLAN are service VLANs.) 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.
