Operation Manual – Cluster Management
H3C S5500-EI Series Ethernet Switches
Follow these steps to configure access between member devices of a cluster:
Switch from the operation
device 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
Caution:
Telnet connection is used on the switch between the management device and member
devices. Note the following when switching between them:
Before the switch, execute the telnet server enable command to enable Telnet.
Otherwise, the switch fails.
Authentication is required when you switch a member device to the management
device. The switch 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, you are not recommended to modify the
super password of the member device (including management device and member
devices) of the cluster; otherwise, the switch may fail because of authentication
failure.
When you switch the management device to a member device, if member n does
not exist, the system prompts error; if the switch 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
switch fails.
To prevent resource waste, avoid recycling switch 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 switch, but not
the cluster switch-to administrator command to switch to the operation interface
of the management device.
