Figure 1 Configuration task flow of Huawei Metro1000 EVPLAN service
Table 1 Description of the configuration task flow of Huawei Metro1000 EVPLAN service
The main difference between EVPLAN service and EPLAN service is that multiple users need to share the bandwidth. Therefore, it is necessary to use the VLAN ID or other mechanisms to distinguish the data of different users. If you need to provide different quality of service for different users, you need to use the corresponding QoS mechanism.
Configuring EVPLAN services requires the use of an Ethernet switching board. See Table 1 for the support of the Ethernet switching veneer for EVPLAN services.
| Procedure | Operation | Remarks |
|---|---|---|
| 1 |
Configure the external port of the Ethernet board |
Required When a network element accesses Ethernet services through the external port of the Ethernet single board, it is necessary to configure various attributes of the external port in order to cooperate with the data communication equipment on the customer side to realize normal access to Ethernet services. |
| 2 |
Configuring the internal ports of the Ethernet single board |
Required When a network element transmits Ethernet services to the SDH side through the internal port (i.e., VCTRUNK) of the Ethernet board, various attributes of the VCTRUNK port need to be configured in order to cooperate with the Ethernet single board on the opposite side of the network element to realize the transmission of Ethernet services in the SDH network. |
| 3 |
Creating Ethernet LAN Services |
Required When using an Ethernet switchboard to carry LAN services, you need to create a bridge and set various attributes of the bridge and the ports to which the bridge is connected. |
| 4 |
Create VLAN filter table |
Required If the bridge type created for Ethernet LAN service is IEEE 802.1q or IEEE 802.1ad, you need to create a VLAN filter table for the bridge if you need to use VLANs to segregate user data. |
| 5 |
Modify the Hub/Spoke attributes of the bridge's hooked ports |
Optional. In the Ethernet LAN service, if you do not want multiple access nodes other than the aggregation node to communicate with each other, you can modify the Hub/Spoke attribute between the access nodes from the default Hub to Spoke. |
| 6 |
Create SDH Service |
Required. In order to enable Ethernet services to be transmitted through the specified time slots on the transmission line, a cross-connection between the VCTRUNK-bound channel and the corresponding time slot on the line board needs to be created. |
| 7 |
Configure Layer 2 switching characteristics.
|
|
| 8 |
Configuring QoS |
Optional Multiple users need to share the bandwidth, and if you need to provide different quality of service to different users, you need to adopt the corresponding QoS mechanism. |
| 9 |
Test Ethernet service channel |
Required After completing the Ethernet service creation, you need to verify the connectivity of the Ethernet service. |
| 10 |
Set performance monitoring parameters for network elements |
Required Start the performance monitoring of the specified network element to obtain the detailed performance record of the network element during operation, which is convenient for the maintenance personnel to monitor and analyze the operation status of the network element. |
| 11 | Backup network element database to the main control board |
Required Ensure that the main control board of the network element can automatically resume operation after losing data or powering down the device by backing up the network element database operation. |
