Use the undo cluster enable command to disable the cluster function.
By default, the cluster function is enabled.
Note that:
z
To create a cluster on a management device through the build command or the auto-build
command, you must first enable the cluster function by executing the cluster enable command.
z
When you execute the undo cluster enable command on the management device, the cluster
function is disabled on the device, and the device stops operating as a management device, and
the cluster and all its members are removed.
z
When you execute the undo cluster enable command on a member device, the cluster function is
disabled on the device, and the device leaves the cluster.
z
When you execute undo cluster enable command on a device that does not belong to any cluster,
the cluster function is disabled on the device, and thus you cannot create a cluster on the device or
add the device to an existing cluster.
Examples
# Enable the cluster function on the switch.
<Sysname> system-view
System View: return to User View with Ctrl+Z
[Sysname] cluster enable
cluster switch-to
Syntax
cluster switch-to { member-number | mac-address H-H-H | administrator }
View
User view
Parameters
member-number : Member number of a member device, ranging from 1 to 255.
mac-address H-H-H : Specifies the MAC address of a member device.
administrator : Switches back from the member device to the management device.
Description
Use the cluster switch-to command to switch between the management device and a member device
for configuration and management.
On the management device, you can switch to the view of a member device to configure and manage
the member device, and then switch back to the management device.
Both switching directions (from the management device to a member device, and from a member
device to the management device) will use Telnet connection. Switching is performed based on the
following rules:
z
Both switching directions will perform authentication. In a switching process, the system will
authenticate the level-3 super password. If the super password on the device that requests the
switching is inconsistent with that on the requested device, the switching fails. When a candidate
device joins the cluster, its super password will automatically synchronize to the supper password
