From the Alarm Type drop-down list, indicate whether the event will be triggered by the rising threshold,
Step 8
falling threshold, or both the rising and falling thresholds.
From the Sample Type drop-down list, choose either Relative or Absolute. Relative restricts the
Step 9
threshold to use the number of occurrences in the user-set sample period. Absolute sets the threshold to
use the total number of occurrences, regardless of time period.
Type in an appropriate number of seconds for the Sample Period field.
Step 10
Type in the appropriate number of occurrences for the Rising Threshold field.
Step 11
Note
Enter the appropriate number of occurrences in the Falling Threshold field. In most cases a falling
Step 12
threshold is set lower than the rising threshold.

FC_MR-4 Threshold Variables Fiber Channel/FICON Enhanced
Mode (MIBs) (continued)
For a rising type of alarm, the measured value must move from below the falling threshold to
above the rising threshold. For example, if a network is running below a rising threshold of
1000 collisions every 15 seconds and a problem causes 1001 collisions in 15 seconds, the excess
occurrences trigger an alarm.
Definition
Transmitted total Fibre Channel frames.
Transmitted total Fibre Channel data bytes within a frame.
Total number of link resets initiated by FCMR port when link
recovery port setting is enabled.
Received GFP frames with single bit errors in the core header (these
errors are correctable).
Received GFP frames with multiple bit errors in the core header
(these errors are not correctable).
Received GFP frames with invalid type (these are discarded). For
example, receiving GFP frames that contain Ethernet data when we
expect Fibre Channel data.
Total number of superblock CRC errors with the receive transparent
GFP frame. A transparent GFP frame has multiple superblocks
which each contain Fibre Channel data.
Total number of ordered sets not complaint to GE/FC (Gigabit
Ethernet/Fibre Channel) standard.
Total number of code groups that violate GE/FC disparity errors.
