retention time received the sending equipment management handshake message or message

management, its state will migrate to Active, otherwise it will migrate to Disconnect。

 When the restoration of communications equipment and management of equipment

members interrupted when the device is in the Disconnect state members will rejoin the cluster

join after the success of members in the management of equipment equipment and the local state

will return to Active。

If topology changes are found, member devices also pass the change information to the

management device through handshake messages。

21.1.6 Managing VLAN

Managing VLAN limits the scope of cluster management. By configuring VLAN, the

following functions can be implemented：

 The management message of cluster (including NDP, NTDP message and handshake

message) will be limited in the management of VLAN, isolated from other messages, which

increases the security。

 Managing devices and member devices to implement internal communications by

managing VLAN。

Cluster management requirements management equipment and members / candidate device

port, including cascade port (when the candidate device is connected by another candidate

equipment and management of equipment, equipment connected to each candidate between ports

are called cascade port) allows management through VLAN, so：

 If the port does not allow VLAN to pass through, the device connected to the port

cannot join the cluster, so the cluster should be connected with the management device before the

cluster, including the cascade port, allowing the management of the VLAN to pass。

 Only when the management of equipment and equipment connected to the member /

candidate port and port default VLAN ID cascade is the management of VLAN, the message will

allow the configuration management of VLAN with no label through, otherwise the message

management must be labeled by VLAN。

For VLAN, see Chapter sixth configuring VLAN"。

21.2 Brief introduction of cluster configuration

Before the user configures the cluster, it is necessary to define the roles and functions of each

device in the cluster, and configure the related functions to do the planning work for the
