Symptom
In an IP MAN network that is newly deployed, the OptiX OSN 6800 is used and the TQM and NS2 boards are configured. Networking: There are five stations in this project. The five stations are located in the same city, forming a 10Gbit/s ring network. The ODU1 SNCP protection is configured.
During the configuration of electrical cross-connect services for GE services, the system indicates that the channel number is illegal.
Cause analysis
When there is an indication for this problem, check whether the input parameters are correct and whether the cross-connect type matches the service type of the board.
Procedure
1. Check if the channel number consists of illegal characters. After checking, we found that the number consists of legal digit characters.
2. Check if the LP port corresponding to the channel number does not exist. After checking we found that the LP port (port 1) exists.
3. Check if each LP port corresponds to a certain type of services by default. On the NE Explorer in T2000, select the TQM board and choose Configuration > WDM Interfaces. Click Advanced Attributes on the displayed dialog box and check the service type for each LP port. It is found that each LP port corresponds to STM-4 services by default. Then, change the service type to GE service. Configure the electrical cross-connections again and the problem is not revisited.
Reference Information
When configuring the electrical cross-connect service, we should pay attention to the fact that the LP port corresponds to a certain service type by default.
