106 You can click Rules Description in column D of the Summary Report. Then the following figure is displayed.
In the preceding figure, the cells under Rules Description of column F describe the cause why each check item is marked Abnormal. For example, the rules of check item "GOU and FG2a Brd Port" are as follows:
1. If the interface boards (FG2a/GOUa) work in active/standby mode, and ports which do not work in load sharing mode are occupied by IPPATH/SCTP (used for L3 networking), the ports must be configured to work in active/standby mode.
2. If two interface boards work in active/standby mode, the attributes of the ports with the same number on the active and standby boards must be the same, namely, the AUTO mode, MTU mode, and flow control mode must be the same.
3. Check the active alarms, and whether the alarm id-21348 exists or not. If exists, list the information of port.
4. The value of MTU in the port attribute must be 1500, and AUTO mode should be recommended as 'AUTO'.
Based on the preceding description, you can learn about when exceptions will occur on the ports of the interface boards.
You can also learn about how to handle the problem based on the information under Measures of column I.
Step 3 Locate and resolve the problem.
After learning the rules, you need to locate and resolve the problem accordingly.
Click a hyperlink in column C to return to the Check Item Summary sheet. Then, click an item in column C or H to navigate to the sheet with specific check results. For example, the following figure is displayed after you click "GOU and FG2a Brd Port" under column C. You can learn that no standby port is configured for port 0 on the board that is housed in slot 26 of subrack 2 of RNC 208 (RNC ID = 208). This information matches rule 1 for the check item (see step 2); therefore, the result is displayed Abnormal. You can handle the problem by

For some complex problems that you cannot handle by yourself, submit tickets in the iCare system to track the progress and close the e-workflow.
