Adding A Candidate Device To A Cluster - 3Com 4210G Series Configuration Manual

the member devices through the management device. You can manage member devices in a cluster
through switching from the operation interface of the management device to that of a member device
or configure the management device by switching from the operation interface of a member device to
that of the management device.
Follow these steps to configure access between member devices of a cluster:
Switch from the operation interface of
the management device to that of a
member device
Switch from the operation interface of
a member device to that of the
management device
Telnet connection is used in the switching between the management device and a member device.
Note the following when switching between them:
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.
When a candidate device is added to a cluster and becomes a member device, its super
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.
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.
If the Telnet users on the device to be logged in reach the maximum number, the switching fails.
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.
