For a cluster to work normally, you must set the packets from the management VLAN to pass the ports
connecting the management device and the member/candidate devices—including the cascade ports—
using the following guidelines:
• If the packets from the management VLAN cannot pass a port, the device connected with the port
cannot be added to the cluster. If the ports — including the cascade ports — connecting the
management device and the member/candidate devices prohibit the packets from the management
VLAN, set the packets from the management VLAN to pass the ports on candidate devices with the
management VLAN auto-negotiation function.
• Only when the default VLAN ID of the cascade ports and the ports connecting the management
device and the member/candidate devices is that of the management VLAN can you set the packets
without tags from the management VLAN to pass the ports; otherwise, only the packets with tags
from the management VLAN can pass the ports.
NOTE:
• If a candidate device is connected to a management device through another candidate device, the
ports between the two candidate devices are cascade ports.

Cluster configuration task list
Before configuring a cluster, you must determine the roles and functions the devices play. You also must
configure the related functions, preparing for the communication between devices within the cluster.
