Enabling Management VLAN Auto-negotiation
The management VLAN limits the cluster management range. If the device discovered by the
management device does not belong to the management VLAN, meaning the cascade ports and the
ports connecting with the management device do not allow the packets from the management VLAN to
pass, and the new device cannot be added to the cluster. Through the configuration of the management
VLAN auto-negotiation function, the cascade ports and the ports directly connected to the management
device can be automatically added to the management VLAN.
Follow these steps to configure management VLAN auto-negotiation:

Configuring Communication Between the Management Device and the Member
Devices Within a Cluster
In a cluster, the management device and member devices communicate by sending handshake
packets to maintain connection between them. You can configure interval of sending handshake
packets and the holdtime of a device on the management device. This configuration applies to all
member devices within the cluster. For a member device in Connect state:
z
If the management device does not receive handshake packets from a member device within the
holdtime, it changes the state of the member device to Disconnect. When the communication is
recovered, the member device needs to be re-added to the cluster (this process is automatically
performed).
z
If the management device receives handshake packets from the member device within the
holdtime, the state of the member device remains Active.
Follow these steps to configure communication between the management device and the member
devices within a cluster:

Configuring Cluster Management Protocol Packets
By default, the destination MAC address of cluster management protocol packets (including NDP,
NTDP and HABP packets) is a multicast MAC address 0180-C200-000A, which IEEE reserved for later
use. Since some devices cannot forward the multicast packets with the destination MAC address of
