Configuring Cluster Management

Cluster management is implemented through Huawei Group Management Protocol version 2 (HGMPv2). By employing HGMPv2, a network administrator can manage multiple switches using the public IP address of one switch in a cluster. The switch that is configured with a public address and performs the management function is known as the management device; and other managed switches are called member devices, which are managed and maintained by the management device. The management device and member devices together form a cluster.

In a complex network environment, a network administrator uses HGMP to manage switches inside the network remotely, which is timesaving and easy to operate.

The network administrator can manage member devices through the management device only by performing the following operations:

l          Create a cluster on the management device

l          Enable Neighbor Discovery Protocol (NDP) and Neighbor Topology Discovery Protocol (NTDP) on member switches

l          Enable HGMP

Networking and Configuration Requirements

l          13 switches form a cluster

l          Switch A serves as the management device, and the other switches are the member devices

l          The management VLAN of the cluster is VLAN 10

l          The IP address of the management switch is 163.172.55.1

l          The IP address of the TFTP server is 63.172.55.1

l          The IP address of the SNMP network management (NM) host is 69.172.55.4

l          All the devices in the cluster use the same FTP server and SNMP host.

Management device:

l          Port GigabitEthernet 1/0/1 belongs to VLAN 2, whose interface IP address is 163.172.55.1

l          The management device connects to two member devices through ports GigabitEthernet 1/0/2 and GigabitEthernet 1/0/3 respectively.

Member devices:

l          Switch B (member device) connects with Switch D, E and F through ports GigabitEthernet 1/0/2, GigabitEthernet 1/0/3 and GigabitEthernet 1/0/4 respectively

l          Switch C (member device) connects with Switch G, H and I through ports GigabitEthernet 1/0/2, GigabitEthernet 1/0/3 and GigabitEthernet 1/0/4 respectively.

l          Switch E (member device) connects with Switches J and K through ports GigabitEthernet 1/0/2 and GigabitEthernet 1/0/3 respectively

Configuration Guidelines

Follow these guidelines when configuring cluster management:

l          Upon completion of the above configurations, you can execute the cluster switch-to { member-number | mac-address H-H-H } command on the management device to switch to the operation interface of a member device to maintain and manage it. You can then execute the cluster switch-to administrator command to return to the operation interface of the management device.

l          You can also reboot a member device by executing the reboot member { member-number | mac-address H-H-H } [ eraseflash ] command on the management device.

l          You can also receive at the SNMP host the logs and SNMP traps of all the member devices.

l          The switches cannot act as a TFTP server.

l          The management VLAN of a cluster defaults to 1. For security purpose, you are recommended to isolate management packets from other packets and configure another VLAN as the management VLAN for a cluster.

l          If the port of an access NM device (including FTP/TFTP server, NM host and log host) does not allow the packets from the management VLAN to pass, the NM device cannot manage the devices in a cluster through the management device. In this case, on the management device, you need to configure the VLAN interface of the access NM device (including FTP/TFTP server, NM host and log host) as the NM interface.

l          You are recommended to set the timers to their default values.

l          After you execute the display cluster current-topology command, the device connecting with a blacklist device will not be displayed.
