CX600 interface automatic up down problem

Publication Date:  2012-07-27 Views:  74 Downloads:  0
Issue Description
we found that some CX600 GE interface have automatic up/down problem itself.
Alarm Information
 Dec  7 2008 06:40:14 EH60WIAN01 %%01RM/3/LDP_SESSION_STATE(l): RM received the status UP of the LDP session on the GigabitEthernet8/0/0.
     Dec  7 2008 06:40:11 EH60WIAN01 %%01LDP/4/NOFINDSOCK(l): The TCP event 4 was received, but failed to find the corresponding Socket 8.
     Dec  7 2008 06:40:11 EH60WIAN01 %%01LDP/4/TCPDOWN(l): Sessions were deleted because the TCP connection turned Down
     Dec  7 2008 06:39:47 EH60WIAN01 %%01OSPF/3/NBR_CHG_DOWN(l): Neighbor event:neighbor state changed to Down. (ProcessId=1, NeighborAddress=195.248.45.29, NeighborEvent=InactivityTimer, NeighborPreviousState=Init, NeighborCurrentState=Down)
     Dec  7 2008 06:39:39 EH60WIAN01 %%01SRM/2/NODERESUME(l):-Slot=8; In PIC0 of LPU8, LANE2_CTC_ERR of PCS STATUS resumed from failure.
Handling Process
it is a very strange problem, we have 10 of CX600, and 2 of them have this problem , the others are OK , both hardware and software of these CX600 all same.
     We make trouble shooting about this problem for a long time, at the end, analyse the hardware with CX600 hardware engineer ,find this reason is: the interface card is too tighten with PIC card, need to change loose a little.
Name:
The PCS module of the L1XX subcard fails.
Location Info:
PhysicalName=LPU Board 8 Event Type=equipmentAlarm PhysicalContainedIn=524288
Relative Resource= Reason=LPU8  is failed, PCS STATUS of PIC0 is abnormal
Description:
The physical entity fails,probably due to component failure.
Reason:
The connector between the PIC card and LPU is not well connected or the PIC card is abnormal.
Root Cause
Null
Suggestions
If found the GE interface automatic up/down without any reason, this case can solved this strange problem.
