7. DIAGNOSIS
The number of faulty occurrences
The timestamp of the first faulty occurrence
The timestamp of the last faulty occurrence
The last faulty result value
NOTE
As long as a certain BIST has never failed, only the index and the latest value measured are reported
via SNMP.
For a complete list of implemented BISTs, see Appendix A.
7.3 Health message
The TTE-Switch A664 Lab v2.0 sends a health message with a period of 1000 ms in the Best Effort Task-1.
The length of the message is the maximum UDP Ethernet frame size (1518 B). The health message is
transmitted on port 24.
The health message consists of:
1. A 1-byte free running counter which is incremented with every transmission.
2. A 1-byte error counter for every BIST that is configured to be executed.
3. The status of the health pin as ASCII string: “HEALTHY” or “FAULT”.
4. The state of the TTE-Switch A664 Lab v2.0 application, for example “OPERATIONAL”.
5. The TTE-SMC2 software synchronization state in the form of an ASCII string: “SYNC: <0-7>”
NOTE
When the TTE-Switch A664 Lab v2.0 is in the SHOP state, Best Effort Task-1 is not executed. Therefore,
the switch will only send a health message when it is not in the SHOP state.
7.4 Life-sign message
The TTE-Switch A664 Lab v2.0 sends a life-sign message with a period of 1000 ms in the Best Effort Task-
2. The length of the message is the minimum UDP Ethernet frame size (64 B). The life-sign message is
transmitted on port 24.
The message consists of an ASCII string in the form of “DDDD:HH:MM:SS:mmm”, where:
1. DDDD are days since start-up [0, 999], with any leading zeros being skipped.
2. HH are hours since start-up [0, 23], with a leading zero being skipped.
3. MM are minutes since start-up [0, 59], with a leading zero being skipped.
4. SS are seconds since start-up [0, 59], with a leading zero being written.
5. mmm are milliseconds since start-up [0, 999], with any leading zeros being written.
NOTE
When the TTE-Switch A664 Lab v2.0 is in the SHOP state, Best Effort Task-2 is not executed. Therefore,
the switch will only send a life-sign message when it is not in the SHOP state.
