The main difference between EVPL service and EPL service is that multiple users need to share the bandwidth, so VLAN ID or other mechanisms need to be used 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.
Figure 1 Configuration task flow of EVPL service
Table 1 Description of the configuration task flow of EVPL service
The configuration of EVPL service requires the use of an Ethernet switching board. See Table 1 for the support of the Ethernet switching veneer for EVPL service.
| Procedure | Operation | Remarks |
|---|---|---|
| 1 |
Configure the external port of the Ethernet switchboard |
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 Private Line Services |
Required When the Ethernet switching veneer carries leased line services, you need to specify information related to leased line services such as service source and host. |
| 4 |
Create SDH service |
Required In order to enable Ethernet services to be transmitted through the specified time slots on the transmission line, it is necessary to create cross-connections between the VCTRUNK-bound channel and the corresponding time slots on the line board. |
| 5 |
Configure 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. |
| 6 |
Test Ethernet service channel |
Required After completing the Ethernet service creation, you need to verify the connectivity of the Ethernet service. |
| 7 |
Set the performance monitoring parameters of the network element |
Required Start the performance monitoring of the specified network element to obtain the detailed performance records of the network element during operation, which is convenient for the maintenance personnel to monitor and analyze the operation status of the network element. |
| 8 | 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. |
