HP Comware 5 Debug Manual Vol 3

Field
Description
RPR_Fsm: On
interface-type
interface-number. String
is running
The String field indicates the current state machine:
• WTR state machine.
• receive TP frame state machine—Receiving TP frames.
• transmit TP frame state machine—Transmitting TP frames.
• topology DB update state machine stage1—Stage 1 of topology database
updating.
• topology DB update state machine stage2—Stage 2 of topology database
updating.
• protection state machine.
• topology validation state machine.
• TC frame processing state machine.
•
ATD frame processing state machine—ATD frame processing state machine.
RPR_Fsm: On
interface-type
interface-number
protection switch event
is overridden by String1
String2
Protection switch.
The String1 field indicates the current protection state event:
• TP_RCVD—Received TP frames.
• WTR_EXP—WTR timer expired.
• AUTO_IDLE—Link recovery event.
• AUTO_SD—Signal degraded.
• AUTO_SF—Signal failure.
• ADMIN_IDLE—Manual recovery.
• ADMIN_MS—Manual switch.
• ADMIN_FS—Forced switch.
The String2 field indicates the switch type:
• locally.
• neighborly.
• distantly.
RPR_Fsm: On
interface-type
interface-number String
Print state machine information. The String field can be:
• protection state machine: in stage START.
• protection state machine: in stage FIRST.
• protection state machine: in stage FINAL.
• protection state machine: in stage POST.
• protection state machine: in stage MAIN.
• The current station is isolate—The current station is isolated.
Examples
# Enable RRPP state machine debugging. The output in this example was created when two stations form
a closed RPR ring. When you remove the optical fiber, output similar to the following example is
generated:
<Sysname> debugging rpr fsm
*Jun 5 11:44:12:982 2007 Sysname RPR/7/FSM_PRTEVT:Slot=5;
RPR_Fsm: On RPR1, at west span, AUTO_SF protection switch is current.
// On interface RPR1, signal failure occurred on the west span.
*Jun 5 11:44:13:142 2007 Sysname RPR/7/FSM:Slot=5;
RPR_Fsm: On RPR1, at west span, protection state machine: in stage START
// On interface RPR1, the protection state machine was in the START stage on the west span.
