PSN Issue :
Previously PSN-2012-03-532 (Tx lockup of the em0 interface causes the em0 interface down and all FRUs to go offline) was announced to provide a solution for the Tx lockup issue on tsec1 (em0) controller, which was applied in Junos OS 10.4R8-R12, 11.1R6, 11.2R3-R7, 11.4R1-R6, 12.1R1-R5 and 12.1X44-D10. However this solution does not resolve other scenarios which cause Tx or Rx lockup issues of the em0 interface related to the communication path for RE to other parts of system:
- Chassis cluster failover
- Chassis cluster split brain
- Severe service impact including restarting of FPCs (applicable to both cluster and single node devices)
Solution: The following fix/enhancement is included in 10.4S12, 10.4R13, 11.4R6-S2, 11.4R7, 12.1R5-S1, 12.1R6 (scheduled to be released during the 1st week of May 2013) and 12.1X44-D15 (scheduled to be released the 1st week of May 2013).
Fix: Enhance the Tx and Rx lockup detection logic and once the error conditions are detected, gracefully reset the Tx or Rx lockup status or reset the MAC of the em0 interface. Then reconfigure the MAC to bring the em0 interface back to a normal working condition.
Note that all the download links of service releases will be removed once all the maintenance releases (e.g., 12.1R6) are posted on the Junos Software download page.
