  • Page 4: How A Cluster Works

    Operation Manual – Cluster Management H3C S3610&S5510 Series Ethernet Switches Chapter 1 Cluster Management Configuration Candidate device: A device that does not belong to any cluster but can be added to a cluster. Different from a member device, its topology information has been collected by the management device but it has not been added to the cluster.
  • Page 5 Operation Manual – Cluster Management H3C S3610&S5510 Series Ethernet Switches Chapter 1 Cluster Management Configuration The management device adds or deletes a member device and modifies cluster management configuration according to the candidate device information collected through NTDP. I. Introduction to NDP NDP is used to discover the information about directly connected neighbors, including the device name, software version, and connecting port of the adjacent devices.
  • Page 6 Operation Manual – Cluster Management H3C S3610&S5510 Series Ethernet Switches Chapter 1 Cluster Management Configuration The management device periodically sends NTDP topology collection request from the NTDP-enabled ports. Upon receiving the request, the device sends NTDP topology collection response to the management device, copies this response packet on the NTDP-enabled port and sends it to the adjacent device.

    Operation Manual – Cluster Management H3C S3610&S5510 Series Ethernet Switches Chapter 1 Cluster Management Configuration IV. Management VLAN The management VLAN limits the cluster management range. Through configuration of the management VLAN, the following functions can be implemented: Management packets (including NDP, NTDP and handshake packets) are restricted within the management VLAN, therefore isolated from other packets, which enhances security.
