Device Is Added And Then Disappears During The Synchronization Because Of The License Issue - Huawei MA5600 Manual

MSAN UA5000 Cases
Handling Proce
1. Ping PCs at the same network segment from the server and find that no packets are lost.
ss:
Therefore, the network adapter is running properly.
2. Scan viruses on the server and find no exception.
3. Log in to and check the uplink 8505 switch, and find the following alarm messages:
3 04:07:44 2008 ZH_XXZ_S8505_A DIAGCLI/5/LOG_WARN:Slot=6;
Detect ARP attack from MAC 0011-43ba-c24f, VLAN: 993, GigabitEthernet6/2/4 !
Where, 0011-43ba-c24f is the MAC address of the N2000 BMS. It can be judged that the 8505
switch considers the N2000 BMS as an exceptional attack user by mistake (the N2000 BMS
broadcasts a large number of ARP packets to obtain the MAC address of DSLAM device during
the resynchronization with the 8505 switch). In this way, the 8505 switch does not forward the
MAC address of the N2000 BMS, and places it into the black hole instead. As a result, all ARP
packets are discarded by the 8505 switch. In this case, when you ping the 8505 switch from the
N2000 BMS, the packets are lost and eventually the ping operation fails (however, you can ping
through other PCs under the 2403 switch). Therefore, the N2000 BMS fails to control the device
properly. Configure the anti-attach ARP exclude MAC address on the 8505 switch as follows:
anti-attack arp exclude-mac mac-address (the MAC address of the N2000 BMS). Then the
problem is solved.
Suggestions and
To solve the problem of the detachment of NEs from the BMS server, you should consider the

Product Family: Access Network Management System
Fault Type: Element Management
Keywords: License, device disappears
Phenomenon De
The BMS version of the N2000 BMS is V2R10C02B015SPC002.
scription:
The MA5300 is added to the N2000 BMS and then disappears during data synchronization. If
the operation is performed in time, the device panel can be displayed before the MA5300
disappears.

Cause Analysi
1. The problem can be traced to insufficient licenses. Query the licenses of the N2000 BMS on
s:
the client and it is found that no item is highlighted in red.
2. When the N2000 BMS is installed, a temporary license is used. Adding the MA5300 is
successful and other operations can be performed on the MA5300. The problem occurs after the
temporary license is replaced with the commercial license. Check the commercial license and
the problem is located.
The versions of the N2000 BMS later than V200R009 use the license file of V200R009. The
license file contains the following four control items:
1> Feature COMMON
Authorizes the validity period and the maximum number of the N2000 BMS clients that can log
in.
2> Feature INSTALL
Authorizes the installation components of the N2000 BMS.
3> Feature BMSWG
Authorizes the service port and the lines.
