Cluster Switch-To - 3Com Switch 4500 Family Manual

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:
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
on the management device (this is not true when you add the candidate device to the cluster using
the administrator-address command). It is recommended not to change the super password of
any cluster member or the management device, so as to avoid switching failure resulting from
authentication failure.
After you switch from the management device to a member device, the member device view will
inherit the user privilege level of the current management device view.
After you switch from a member device to the management device, the privilege level on the
management device view will be determined by the configuration on the management device.
If all the Telnet resources on the requested device are used up, the switching to the device will not
succeed.
