IV. Management VLAN
The management VLAN limits the cluster management range. Through configuration of
the management VLAN, the following functions can be implemented:
z
Management packets (including NDP, NTDP and handshake packets) are
restricted within the management VLAN, therefore isolated from other packets,
which enhances security.
z
The management device and the member devices communicate with each other
through the management VLAN.
For a cluster to work normally, you must set the packets from the management VLAN
to pass the subtending ports (If a candidate device is connected to the management
device through another candidate device, the ports connecting these two candidate
devices are called subtending ports.) and the ports connecting the management device
and the member/candidate devices. Therefore:
z
If the packets from the management VLAN cannot pass a port, the device
connected with the port cannot be added to the cluster. Therefore, if the ports
(including the subtending ports) connecting the management device and the
member/candidate devices prohibit the packets from the management VLAN, you
can set the packets from the management VLAN to pass the ports on candidate
devices with the management VLAN auto-negotiation function.
z
Only when the default VLAN ID of the subtending 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.
Refer to the
VLAN
part of the manual.
1.2 Cluster Configuration Task List
Before configuring a cluster, you need to determine the roles and functions the devices
play. You also need to configure the related functions, preparing for the communication
between devices within the cluster.
