HP 5820X Switch - Configuring Access between the Management Device and Its Member Devices

154
Configuring access between the management
device and its member devices
After having successfully configured NDP, NTDP and cluster, configure, manage and monitor 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.
To configure access between member devices of a cluster:
To do… Use the command… Remarks
1. Switch from the operation
interface of the management
device to that of a member
device.
cluster switch-to { member-number
| mac-address mac-address |
sysname member-sysname }
Required
2. Switch from the operation
interface of a member device
to that of the management
device.
cluster switch-to administrator Required
CAUTION:
Telnet connection is used in the switching between the management device and a member device.
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
with the level of 3 will be automatically synchronized to the management device. After a cluster is
established, do not 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.
