Cnfxbarerrthresh - Cisco MGX 8850 Command Reference Manual

cnfxbarerrthresh

cnfxbarerrthresh
Configure Crossbar Error Threshold—specify a threshold for a particular crossbar error
The Syntax Description contains a list of possible errors. A crossbar error threshold consists of:
•
•
•
Note The default settings for crossbar error thresholds are optimal for nearly all applications. The
dspxbarerrthresh command shows the existing thresholds. If necessary, you can change thresholds
through the cnfxbarerrthresh command.

9-38
A period for counting errors
Severity of the resulting alarm (minor, major, and critical)
Upper and lower counts for each alarm severity
A number that identifies the type of error, as follows:
1. Loss of synchronization (LossOfSync).
2. Transceiver error (TranscieverErr)
3. DisparityErr—an accumulation of five ASIC-level errors
4. ParityErr—a parity error in the switch frame as a whole
HeaderCRCErr—a CRC error for the switch frame header
5.
PayloadCRCErr—a CRC error for the switch frame payload
6.
RemapTwiceErr
7.
8. RemapRecurrErr
Backpressure parity error (B.P.ParityErr)—a parity error in the signaling for
9.
backpressure
The number of milliseconds over which the system counts errors.
The severity of the alarm resulting from the error count per threshold time.
The clear count is the number of errors below which the alarm changes to the next
lowest severity. For example, the system clears a minor alarm for a particular type of
error when the number of errors goes to 0. Similarly, if clrcnt for a major alarm is 30,
the alarm goes to minor when the count drops below 30.
