FD Networking Scenarios

Networking Scenarios

Based on the actual hardware configurations, the FD system can implement line fiber quality monitoring in two-fiber bidirectional and single-fiber bidirectional networking scenarios. This topic describes the typical networking scenarios for line fiber quality monitoring.

Precaution

·    The TN12ST2 or TN11AST2 board can be connected to an FIU, DAPXF, SFIU, OLSP or OLSPA/OLSPB board.

·    The FIU board connected to a TN12ST2 or TN11AST2 board and its peer FIU board must be TN13FIU03, TN16FIU01, or TN11SFIU01.

·    The DAPXF board connected to TN12ST2 or TN11AST2 is TN52DAPXF. Within the same OMS, the DAPXF board can be interconnected with an FIU, SFIU, or another DAPXF board, but the interconnected boards must have the same mode. In other words, the interconnected boards must all function as FIU boards or all function as SFIU boards. If the board modes are different, the fiber quality monitoring function becomes unavailable.

·    The OLSP board connected to a TN12ST2 or TN11AST2 board and its peer OLSP board must be TN11OLSP01. The OLSP board is used in the two-fiber bidirectional transmission scenario.

·    The OLSPA/OLSPB board connected to the TN12ST2 or TN11AST2 board and the peer OLSPA/OLSPB board can be only TN11OLSPA01 or TN11OLSPB01, and TN11OLSPA and TN11OLSPB boards must be used in pairs. For example, if TN11OLSPA01 is used at one end of a fiber, TN11OLSPB01 must be used at the other end of the fiber. The OLSPA/OLSPB board is used in the single-fiber bidirectional transmission scenario.

·    On a short fiber span, a fixed optical attenuator (FOA) needs to be added so that the fiber insertion loss is greater than 15 dB, preventing a receiver overload issue. For a TN12ST2 or TN11AST2 board, the fixed optical attenuator (FOA) can be configured only on the RMn port of the board rather than the TMn or TXn port of other OSC boards.

·    The TN11AST2 board can be interconnected only with the same board and the TNF1AST4 board on OptiX OSN 1800.

In the Huawei Cloud Managed Network Solution, switches are deployed at the access or aggregation layer of a campus network for data forwarding. Compared with traditionally-managed switches, cloud-managed switches are plug-and-play and can automatically register with the cloud management platform over the Internet for zero touch deployment. Additionally, cloud-managed switches allow delivering operations through the cloud management platform anytime, anywhere, achieving fast batch service configuration.

the egress gateway also functions as the DHCP server, which is configured with Option 148 containing the device management mode and cloud management platform's address information. Using DHCP, switches automatically change to the cloud-based management mode, obtain the cloud management platform's address information, and become plug and play. This networking applies to the enterprise-built cloud management platforms that are not connected to the Huawei device registration query center.

I am a little confused about this, can you explain more?  thank you!

any other board type support for this?

 

The OLSPA/OLSPB board is used in the single-fiber bidirectional transmission scenario

This is exactly what I was looking for. I have been stuck for a long time on this problem. you gave me a very good idea ,I very much appreciate it.

Please keep on post and share more cases for all of us

After read this part , i solved one issue .The DAPXF board connected to TN12ST2 or TN11AST2 is TN52DAPXF. Within the same OMS, the DAPXF board can be interconnected with an FIU, SFIU, or another DAPXF board, but the interconnected boards must have the same mode. In other words, the interconnected boards must all function as FIU boards or all function as SFIU boards. If the board modes are different, the fiber quality monitoring function becomes unavailable.

SNMP identifies and encrypts data in the USM to reduce and defend the preceding attacks.
Discrimination: The data integrity and data source are discriminated to ensure that messages are sent from the source and data packets are not forged or modified during transmission. The MD5 and SHA are used to obtain data digest and verify whether data is modified.
Encryption: The data is encrypted, so data packets cannot be intercepted by network technologies such as packet header obtaining. The DES or AES ensures the efficiency and strength of data encryption and decryption. This post was last edited by SupperRobin at 2018-10-31 06:44.
