FPC Performing action log for error

Solution

Indications:

  • No service impact
  • This error is a transient hardware problem if it doesn't re-occur 
  • Error condition on the FPC is auto recovered by the software

 Causes:

  • For Pechip, when the bit position flipped in respective memory triggers the error message to appear “corrected_l3_table”
  • Subsequently, the value of this led to the alarm getting recovered
  • L3_table is the level 3 table of the grant scheduler and corresponds to the Output Queue table. The error message indicates a memory issue with this table which got cleared. L1 table error got cleared automatically and did not have any service impact.

These logs refer to an transient ECC error. These errors are typically autocorrected by software automatically and usually no further action is needed on your end and these entries should cease to appear.

You can also reboot the line card to clear the transient error or clear the error with "clear chassis fpc errors fpc-slot X all"
