H3C Technologies H3C MSR 50 - Manual (Page 78)

Step Command Remarks
Optional.
123. Specify the management
VLAN.
management-vlan vlan-id
By default, VLAN 1 is the
management VLAN.
124. Enter cluster view. cluster N/A
125. Configure the private IP
address range for member
devices.
ip-pool ip-address { mask |
mask-length } By default, no private IP address
range is configured.
• Manually establish a cluster:
build cluster-name Use either method.
126. Establish a cluster. • Automatically establish a
cluster:
auto-build [ recover ]
By default, the device is not the
management device.
Enabling management VLAN autonegotiation
Management VLAN limits the cluster boundaries. To assign a device to a cluster, you must make sure the
port that directly connects the device to the management device or its cascade ports are in the
management VLAN.
Management VLAN autonegotiation enables a cluster management device to add ports directly
connected to it and cascades ports between cluster candidate devices to a management VLAN.
To enable management VLAN autonegotiation on the management device:
Step Command Remarks
127. Enter system view. system-view N/A
128. Enter cluster view. cluster N/A
129. Enable management VLAN
auto-negotiation. management-vlan synchronization
enable By default, this function is
disabled.
Configuring communication between the management device
and the member devices within a cluster
In a cluster, the management device and its member devices communicate by sending handshake
packets to maintain a connection. You can configure the interval for 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:
• 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).
• If the management device receives handshake packets from the member device within the holdtime,
the state of the member device remains Active.
