R2511-HP MSR Router Series Network Management and Monitoring Configuration Guide(V5)

58
To ensure security of the cluster management VLAN, PCs and other network devices that do not belong
to the cluster are not allowed to join the management VLAN, only ports on devices of the cluster can join
the management VLAN.
IMPORTANT:
To
g
uarantee the communication within the cluster, ensure VLAN handlin
g
consistency on all ports on the
path from a member device or candidate device to the management device. To remove the VLAN ta
g
of
out
g
oin
g
mana
g
ement VLAN packets, set the mana
g
ement VLAN as the PVID on all the ports, includin
g
hybrid ports. If the management VLAN is not the PVID, a hybrid and trunk port must send outgoing
management VLAN packets with the VLAN tag.
For more information about VLAN, see Layer 2—LAN Switching Configuration Guide.
Configuration restrictions and guidelines
• Do not disable NDP or NTDP after a cluster is formed. Doing so on the cluster management device
or its member devices does not break up the cluster, but can affect operation of the cluster.
• If an 802.1X- or MAC authentication-enabled member device is connected to any other member
device, enable HABP server on the device. Otherwise, the management device of the cluster cannot
manage the devices connected to it. For more information about HABP, see Security Configuration
Guide.
• Before you establish a cluster or add a device to the cluster, verify that:
{ The management device's routing table can accommodate routes destined for the candidate
devices. A full routing table can cause continual additions and removals of all candidate
devices.
{ The candidate device' routing table can accommodate the route destined for the management
device. A full routing table can cause continual additions and removals of the candidate device.
Cluster management configuration task list
Before configuring a cluster, determine the roles and functions the devices play, and configure functions
required for the cluster member devices to communicate with one another.
Complete these tasks to configure cluster management functions:
Task Remarks

• Enabling NDP globally and for specific ports
Required.
• Configuring NDP parameters
Optional.
• Enabling NTDP globally and for specific ports
Required.
• Configuring NTDP parameters
Optional.
• Manually collecting topology information
Optional.
• Enabling the cluster function
Required.
• Establishing a cluster
Required.
• Enabling management VLAN autonegotiation
