Introduction To Ndp - H3C S7500 Series Operation Manual

Operation Manual – Cluster
H3C S7500 Series Ethernet Switches
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.
Functions of topology discovery and display, which assist network monitoring and
debugging
Software upgrading and parameter configuring can be performed simultaneously
on multiple switches.
Free of topology and distance limitations
Saving IP address resource
HGMP V2 is comprised of the following three protocols:
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.
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.
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 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.
