In the IP transmission mode, this describes how to trace IP messages between the BSC and BTS, the MSC and BSC, or between the interface boards in the BSC on the LMT.
Prerequisites
- The LMT runs normally.
- The communication between the LMT and the BSC is normal.
Context
- For details of Message Type, refer to Message Types.
- For details of Tracing Mode, refer to Tracing Modes.
In the Trace IP Message dialog box, specify the location parameters. Table 1 lists the parameters shown in the Trace IP Message dialog box.
Parameter |
Meaning |
|
|---|---|---|
IP Information |
Source IP Address |
Source IP address by which the datagram packet is sent, for example, the port IP address at the BSC side is 172.16.5.156. This parameter is set according to the actual requirements. |
Destination IP Address |
Destination IP address to which the datagram packet is sent. The port IP address at the BTS side, for example, is 172.20.7.40. This parameter is set according to the actual requirements. |
|
Source Port No./Destination Port No. |
Source port number/destination port number of the OML, RSL or EML link. For example, the source port number of an RSL link is 12288, and the destination port number of the RSL link is 12288. This parameter is set according to the actual requirements. Value range: 0-65535. |
|
Protocol Type |
Consisting of the UDP and SCTP protocols. The protocol type used depends on the services. |
|
Position Information |
Subrack No./Slot No. |
Subrack number and slot number of the IP-based interface board or transmission optimization interface board. |
The following description is based on the configuration using the GOMU.
Procedure
- On the Trace & Monitor tab page, choose . A dialog box is displayed, as shown in Figure 1.
- In the IP Information area, enter the corresponding information. Then, set the parameters in the Position Information and Tracing Mode areas.
- Click OK.
Result
If the operation is successful:
- If the Tracing Mode is set to Save on GOMU, the LMT does not display the traced messages. You can view the output file of the traced messages. For details, refer to Reviewing Trace Message Files.
- If the Tracing Mode is set to Report, a dialog box is displayed, prompting the information of the message tracing task.
If the operation fails, a dialog box is displayed, prompting the possible causes.
