1.1 Cluster Overview
1.1.1 Introduction to HGMP V2
A cluster is implemented through Huawei group management protocol (HGMP V2). By
employing HGMP V2, a network administrator can manage multiple switches using the
public IP address of a switch known as a management device. The switches under the
management are member devices. The management device, along with the member
devices, forms a cluster. Normally, a public IP address is not assigned to a member
device. Management and maintenance operations intended for the member devices in
a cluster are redirected by the management device.
Figure 1-1 illustrates a typical
cluster implementation.

z Simplifying the procedures to configure multiple switches. After assigning a public
IP address to the management device, you can configure/manage a specific
member device on the management device instead of logging in to it in advance.
z Functions of topology discovery and display, which assist network monitoring and
debugging
z Software upgrading and parameter configuring can be performed simultaneously
on multiple switches.
z Free of topology and distance limitations
z Saving IP address resource
HGMP V2 is comprised of the following three protocols:
z Neighbor Discovery Protocol (NDP): HGMP V2 implements NDP to discover the
information about the directly connected neighbor devices, including device type,
software/hardware version, connecting port and so on. The information including
device ID, port mode (duplex or half duplex), product version, and Boot ROM
version can also be given.
z Neighbor Topology Discovery Protocol (NTDP): HGMP V2 implements NTDP to
collect the information about the network topology, including the device
connections and the device information in the network. The hop range for topology
discovery can be adjusted manually.
z Cluster management protocol: The cluster management protocol provides the
member recognition and member management function. It can also perform
large-scaled device management together with the network administrator.
Member recognition means that the management device recognizes each
member in the cluster through locating each member and then distributes the
configuration and management commands to the members. Member
management means to manage the following events through the management
device, including adding a member, removing a member, and the member’s
authentication on the management device. Member management also manages
the cluster parameters including interval of sending handshake packets,
management VLAN of the cluster, public FTP server of the cluster.
Cluster-related configurations are described in the following sections.
1.1.2 Introduction to NDP
NDP is the protocol for discovering the information about the adjacent nodes. NDP
operates on the data link layer, so it supports different network layer protocols.
NDP is used to discover the information about directly connected neighbors, including
the device type, software/hardware version, and connecting port of the adjacent
devices. It can also provide the information concerning device ID, port simplex/duplex
status, product version, and Boot ROM version.
Operation Manual – Cluster
H3C S7500 Series Ethernet Switches Chapter 1
Cluste
r
1-3
An NDP-enabled device maintains an NDP information table. Each entry in an NDP
table ages with time. You can also clear the current NDP information manually to have
adjacent information collected again.
An NDP-enabled device broadcasts NDP packets regularly to all active ports. An NDP
packet carries the holdtime field, which indicates the period for the receiving devices to
keep the NDP data. Receiving devices store only the information carried in the received
NDP packets rather than forward them. The corresponding data entry in the NDP table
is updated when the received information is different from the existing one. Otherwise,
only the holdtime of the corresponding entry is updated.
1.1.3 Introduction to NTDP
NTDP is a protocol for network topology information collection. NTDP provides the
information about the devices that can be added to clusters and collects the topology
information within the specified hops for cluster management.
Based on the NDP information table created by NDP, NTDP transmits and forwards
NTDP topology collection requests to collect the NDP information and neighboring
connection information of each device in a specific network range for the management
device or the network administrator to implement required functions.
Upon detecting a change occurred on a neighbor, a member device informs the
management device of the change through handshake packets. The management
device then collects the specified topology information through NTDP. Such a
mechanism enables topology changes to be tracked in time.
Note:
As for NTDP implementing, you need to perform configurations on the management
device, the member devices, and the candidate devices as follows:
z On the management device, enable NTDP both globally and for specific ports, and
configure the NTDP settings.
z On each member device and candidate device, enable NTDP both globally and for
specific ports. As member devices and candidate devices adopt the NTDP settings
configured for the management device, NTDP setting configurations are not
needed.
z NTDP takes effect in the management VLAN only. S7500 series Ethernet switches
take VLAN 1 as the management VLAN, that is, the NTDP function of the S7500
series takes effect in VLAN 1 only.

1.1.4 Introduction to Cluster
I. Introduction to cluster configuration
A cluster has one (and only one) management device. Note the following points when
creating a cluster:
z You need to designate a management device first. The management device of a
cluster is the portal of the cluster. That is, any operations performed in external
networks and intended for the member devices of a cluster, such as accessing,
configuring, managing, and monitoring, can only be implemented through the
management device.
z The management device of a cluster recognizes and controls all the member
devices in the cluster, no matter where they are located in the network or how they
are connected.
z The management device collects topology information about all the member and
candidate devices to provide useful information for users to establish a cluster.
z The management device manages and monitors the devices in the cluster by
collecting and processing NDP/NTDP packets. NDP/NTDP packets contain
network topology information.
All the above-mentioned operations need the support of the cluster function.
Note:
You need to enable the cluster function and configure cluster parameters on a
management device. However, you only need to enable the cluster function on the
member devices and candidate devices.
II. Introduction to function of cluster
Cluster provides the function of batch management for the switches in the network. It
provides external management and maintenance applications, including SNMP,
command line, program and data loading, log reporting and alarm reporting. These
applications can be divided into internal-to-external applications and
external-to-internal applications. All the applications are processed according to the
following procedures:
z The communication between the management device and member device in the
cluster is implemented through packet interaction in the management VLAN.
z The communication between the cluster and the external server is implemented
by the Layer 3 interface of the cluster management VLAN.
z When the member device in the cluster communicates with the external server,
the member device transmits the data to the management device first, and then
Operation Manual – Cluster
H3C S7500 Series Ethernet Switches Chapter 1
Cluste
r

the management device transmits the data to the external server. When the
management program running on the external server manages the member
device, the external server transmits the protocol packets to the management
device first, and then the management device forwards the protocol packets to the
member device.
You can configure public FTP servers, TFTP servers, logging hosts and SNMP hosts
for the whole cluster. The management device in the cluster is the default public FTP
server of the cluster when the public FTP server of the cluster is not configured. Cluster,
together with the network management system, can perform large-scaled device
management.
Note:
The S7500 series manage the cluster with VLAN 1, which serves as the management
VLAN in the cluster. You are required to configure the IP address of the Layer 3 virtual
interface of the management VLAN before setting up a cluster. Otherwise, the cluster
cannot be set up successfully. After the cluster is set up, you are not allowed to modify
the IP address of the management VLAN interface.
1.1.5 Switch Roles in the Cluster
According to their functions and status in a cluster, switches in the cluster play different
roles. You can specify the role a switch plays. A switch also changes its role according
to specific rules.
The following three switch roles exist in a cluster: management device, member device,
and candidate device.
