After being removed from the Cluster, a Member Switch becomes a Candidate
Switch again.
The Commander Switch becomes a Candidate Switch only when the Cluster
is Deleted.
NOTE: The XMS-1024P Switch cannot be configured as Commander
Switch and cannot manage the Cluster.
Introduction to Cluster
The Cluster functions used to Configure and Manage the Switches in the Cluster are
based on three protocols, NDP, NTDP and CMP (Cluster Management Protocol).
NDP: All Switches get Neighbor information by collecting NDPs.
NTDP: The Commander collects NDP information and neighboring connection
information of each device in a specified Network range to determine the Candidate
Switches in the Cluster.
Cluster Maintenance: The Commander adds Candidate Switches to the Cluster and
removes Member Switches from the Cluster using the collected NTDP information.
The Cluster module is used for Cluster Management Configuration and includes three
submenus:
NDP, NTDP and Cluster.
15.1 NDP
NDP (Neighbor Discovery Protocol) is used to pass the information of directly con-
nected Neighbor Devices to support Cluster establishment. An NDP-Enabled device
sends NDP packets regularly to Neighbor Devices as well as receiving NDP packets from
Neighbor Devices. An NDP packet carries NDP information (including the Device Name,
MAC Address, Firmware Version, etc…).
