Configuration Procedure

This section describes the procedure for configuring L2 DCN.

NOTE:

To prevent loops in an L2 DCN and further prevent broadcast storms, the STP/RSTP protocol needs to be enabled for a switch that is connected to the L2 DCN.
This example provides the configurations of only the typical NEs: NE11, NE12, NE21, and NE41.

Parameter	Value
New ID	11	12	21	41
New Extended ID	9	9	9	9

Set NE Communication Parameters.

The values for the related parameters are provided as follows.

Configure DCC channels

The values for the related parameters are provided as follows.

Disable the automatic extended ECC function, which is enabled by default on the NMS ports of NEs.
Disable OSPF for NE11 and NE12.
The values for the related parameters are provided as follows.

Create static IP routes for NE11 and NE12.
The values for the related parameters of NE11 are provided as follows.

Parameter

255.255.255.0

Gateway
10.3.2.12

10.3.2.12

The values for the related parameters of NE12 are provided as follows.

Parameter

Value (NE12)

Destination Address

See Enabling/Disabling the RSTP Protocol When the L2 DCN Solution Is Used and verify that Config Status of the RSTP protocol is set to Auto or Enabled for NE11, NE12, NE21, and NE41.
Create NEs by using the Search Method (U2000).
The search domains are 10.3.1.0, 10.3.2.0, and 10.3.3.0.

In normal cases, all the NEs can be created on the centralized NMS.

Parameter	Value
OSPF Status	Disabled	Disabled

To ensure the normal communication between Huawei NMS and Huawei NEs, configure static routes for related routers.
To ensure proper communication between the third-party NMS and third-party radio equipment, see Planning Information About IP Routes of Third-Party Radio Equipment to configure the static routes of the third-party radio equipment.
