To do… Use the command… Remarks
Switch from the operation interface of the
management switch to that of a member switch
cluster switch-to { member-number |
mac-address mac-address | sysname
member-sysname }
Required
Switch from the operation interface of a member
switch to that of the management switch
cluster switch-to administrator Required
CAUTION:
Telnet connection is used in the switching between the management switch and a member switch. Note the
following when switching between them:
• Authentication is required when you switch from a member switch to the management switch. The
switching fails if authentication is not passed. If authentication is passed, your user level is allocated b
the management switch according to the predefined level.
• When a candidate switch is added to a cluster and becomes a member switch, its super password with
the level of 3 will be automatically synchronized to the management switch. Therefore, after a cluster is
established, it is not recommended to modify the super password of any member (including the
management switch and member switches) 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 switch is retained.
• If the Telnet users on the switch to be logged in reach the maximum number, the switching fails.
• To prevent resource waste, avoid ring switching
when confi
urin
access between cluster members. For
example, if you switch from the operation interface of the management switch to that of a member switch
and then need to switch back to that of the management switch, 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 switch.
Adding a candidate switch to a cluster
Follow these steps to add a candidate switch to a cluster:

Configuring topology management
The concepts of blacklist and whitelist are used for topology management. An administrator can
diagnose the network by comparing the current topology (namely, the information of a node and its
neighbors in the cluster) and the standard topology.
