To do… Use the command… Remarks
Switch from the operation
interface of a member device to
that of the management device
cluster switch-to
administrator
Required
Telnet connection is used in the switching between the management device and a member device.
Note the following when switching between them:
z
Authentication is required when you switch from a member device to the management device. The
switching fails if authentication is not passed. Your user level is allocated according to the
predefined level by the management device if authentication is passed.
z
When a candidate device is added to a cluster and becomes a member device, its level 3 password
will be automatically synchronized to the management device. Therefore, after a cluster is
established, it is not recommended to modify the super password of any member (including the
management device and member devices) of the cluster; otherwise, the switching may fail
because of an authentication failure.
z
If the member specified in this command does not exist, the system prompts error when you
execute the command; if the switching succeeds, your user level on the management device is
retained.
z
If the Telnet users on the device to be logged in reach the maximum number, the switching fails.
z
To prevent resource waste, avoid ring switching when configuring access between cluster
members. For example, if you switch from the operation interface of the management device to that
of a member device and then need to switch back to that of the management device, use the quit
command to end the switching, but not the cluster switch-to administrator command to switch to
the operation interface of the management device.
