Problem Description
High traffic loads, around 200 M bit/sec, on interfaces with revisions A0 or B0 of PA-A3-OC12, MM or SMI, in combination with HW rev 2.04, board revision A0, B0 and B1 for VIP4-50 or VIP4-80 can cause the Port Adapter to reset and stop passing traffic. The command show interface atmx/y will display all output queue drops in addition to the messages in the system and versatile interface processor (VIP) log, as shown in the symptoms section in this Field Notice.
Background
Thought to be a flaw in manufacturing, a borderline voltage on a phase-locked-loop (PLL) line was found to cause unpredictable behavior of an ASIC. A 3.3volt (V) sensor was multi-sourced and both parts were not electrically equivalent, failing part was removed from board.
Problem Symptoms
Failing Combinations
PA-A3-OC12MM/SMI: HW rev 2.00, Board revision A0 or B0
IN COMBINATION WITH:
VIP4-50 or VIP4-80: HW rev 2.04, Board revision A0, B0 and B1
The error message will look resemble:
00:18:12: %ATMPA-0-BATMANERROR: misc_cntl_reg 0x38663866. Resetting the OC12 PA...
On the Versatile Interface Processor (VIP) the following error will be displayed:
00:20:16: %ATMPA-3-SAROP: RX SAR doing CM622_RX_CMD_UPDATE_COUNTERS error: command indication time-out
Workaround/Solution
Use version C0 or higher for the Port Adapters PA-A3-OC12, MM or SMI, when used with board revision A0, B0 and B1 for VIP4-50 or VIP4-80.
Submit a return materials autorization (RMA) Port Adapter only upon failure, do not submit an RMA the VIP.
The workaround is to clear the interface until the errors happen again.
A shut, no shut command can be used, or using clear int atm xxx will work also.
