enough. To achieve this, MAPS monitors ports for the following states: IO_PERF_IMPACT and
IO_FRAME_LOSS.
The following table lists the monitored parameters in this category.
Fabric Performance Impact category parameters
TABLE 14
Monitored Parameter
Description
IO_PERF_IMPACT
When a port does not quickly clear the frames sent through it, this can cause a
backup in the fabric. When MAPS detects that the backpressure from such a
condition is significant enough, the bottleneck state of that port is changed to
“IO_PERF_IMPACT”.
IO_FRAME_LOSS
When a timeout is seen on a port, the bottleneck state of that port is changed to
“IO_FRAME_LOSS”. This state will also be set if the Inter-Frame-Time (IFT) or
Average R_RDY_DELAY is greater than or equal to 80ms.
For more information on Fabric Performance Impact monitoring, refer to
on page 85.
Switch Policy Status
The Switch Policy Status category enables you monitor the health of the switch by defining the number
of types of errors that transitions the overall switch state into a state that is not healthy. For example,
you can specify a switch policy so that if a switch has two port failures, it is considered to be in a
marginal state; if it has four failures, it is in a critical (down) state.
The following table lists the monitored parameters in this category and identifies the factors that affect
their health.
NOTE
Not all switches support all monitors.
Switch Policy Status category parameters
TABLE 15
Monitored parameter
Description
Power Supplies (BAD_PWR)
Power supply thresholds detect absent or failed power supplies, and power
supplies that are not in the correct slot for redundancy.
Temperatures (BAD_TEMP)
Temperature thresholds, faulty temperature sensors.
Fans (BAD_FAN)
Fan thresholds, faulty fans.
Flash (FLASH_USAGE)
Flash thresholds.
Marginal Ports
(MARG_PORTS)
Thresholds for physical ports, E_Ports, and F_Ports (both optical and copper).
Whenever these thresholds are persistently high, the port is marginal.
Faulty Ports (FAULTY_PORTS) Hardware-related port faults.
Missing SFPs (MISSING_SFP)
Ports that are missing SFP media.
Error Ports (ERR_PORTS)
Ports with errors.
