originally connected interface to the currently connected interface instead of reconfiguring the features 
defined in the PoE profile one by one, simplifying the PoE configurations. 
The device supports multiple PoE profiles. You can define PoE configurations based on each PD, save the 
configurations for different PDs into different PoE profiles, and apply the PoE profiles to the access 
interfaces of PDs accordingly.

Step Command 
1.  Enter system view. 
system-view 
2.  Enter PoE interface view. 
interface interface-type interface-number  
3.  Apply the PoE profile to the current PoE interface. apply poe-profile  { index  index  |  name  profile-name  } 
 
A PoE profile can be applied to multiple PoE interfaces, while a PoE interface can be applied with only 
one PoE profile.

•  In the third case, you need to remove the application of the undesired PoE profile to the PoE 
interface. 
Configuring an AC input under-voltage threshold fails 
Analysis  
The AC input under-voltage threshold is greater than or equal to the AC input over-voltage threshold. 
Solution 
You can drop the AC input under-voltage threshold below the AC input over-voltage threshold.

Configuring cluster management 
Overview 
Cluster management is an effective way to manage large numbers of dispersed network switches in 
groups. Cluster management offers the following advantages: 
•  Saves public IP address resources. You do not have to assign one public IP address for every cluster 
member switch.  
•   Simplifies configuration and management tasks. By configuring a public IP address on one switch, 
you can configure and manage a group of switches wi thout the trouble of...

As shown in Figure 57, the s witch configured with a public  IP address and performing the management 
function is the management switch, the other managed switches are member switches, and the switch 
that does not belong to any cluste r but can be added to a cluster is a candidate switch. The management 
switch and the member switches form the cluster.

information carried in the NDP packet is different from the stored information, the corresponding 
entry and holdtime in the NDP table are updated; otherwise, only the holdtime of the entry is 
updated. If an entry’s holdtime ex pires (in other words, no NDP information from the neighbor is 
received to restart the hold time before it ages out), the entry is removed from the NDP table. 
NDP runs on the data link layer, and supports different network layer protocols.

Figure 59 Management/member switch state change 
 
 
A cluster manages the state of its member devices as follows: 
•  After a cluster is created and a candidate switch  is added to the cluster and becomes a member 
switch, the management switch saves the state information of the member switch and identifies it as 
Active. And the member switch also saves its stat e information and identifies itself as Active. 
•   After a cluster is created, its management switch  and member switches begin to...

For a cluster to work normally, you must set the packets from the management VLAN to pass the ports 
connecting the management switch and the member/candidate switches (including the cascade ports). 
Therefore: 
•   If the packets from the management VLAN cannot  pass a port, the switch connected with the port 
cannot be added to the cluster. Therefore, if th e ports (including the cascade ports) connecting the 
management switch and the me mber/candidate switches prohibit the packets from the...
