The line card status does not reflect transient errors until FTOS encounters five recoverable or 50 phantom
transient errors on a card within an hour, as shown in Figure 61-9. The text “Last Event” indicates the last
type of parity error (transient or real) that occurred.
Use SNMP to poll the number of transient errors using the objects chSysCardParityPhantomError and
chSysCardParityRecoverableError. If it has been more than one hour since the last occurrence of the same
type of error, the counter associated with that type of error is reset to 1.
Figure 61-9. Viewing the Parity Status of a Line Card
Recognize a non-recoverable parity error
FTOS generates a message similar to Message 12 when it encounters a real transient parity error.
FTOS also generates an SNMP trap, TR_CHM_SRAM_PARITY_NONRECOVERABLE, at the same
time it generates a console message for non-recoverable parity errors. Use SNMP to poll the number of
non-recoverable errors using the objects chSysCardParityNonrecovrableError.
