MAPS monitoring categories
33
Switch Status monitoring category
The Switch Status category enables you to 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 down state.
Table 112 lists the current overall Switch Status category parameters in a switch and identifies the
factors that affect their health. Note that not all switches use the listed monitors.
Fabric monitoring category
The Fabric category groups areas of potential problems arising between devices, such as zone
changes, fabric segmentation, downed E_Ports, fabric reconfiguration, domain ID changes, and
fabric logins.
Table 113 lists measures in the Fabric category and describes each measure.
TABLE 112
Switch status measures
Measure 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.
WWN (WWN_DOWN) Faulty WWN card (applies to modular switches).
HA out of sync (HA_SYNC) High availability (HA) state of the active CP is out of synchronization with the HA
state of the standby CP.
Blades (FAULTY_BLADE) Faulty blades (applies to modular switches).
Core Blade (DOWN_CORE) Faulty core blades.
Flash (FLASH_USAGE) Flash thresholds.
Marginal Ports
1
(MARG_PORTS)
1. Marginal ports, faulty ports, error ports, and missing SFP transceivers are calculated as a percentage of the
physical ports (excluding FCoE and VE_Ports).
Physical port, E_Port, FOP_port (optical), and FCU_Port (copper) port
thresholds. Whenever these thresholds are persistently high, the port is
Marginal.
Faulty Ports
1
(FAULTY_PORTS) Hardware-related port faults.
Missing SFPs
1
(MISSING_SFP) Ports that are missing SFP transceiver.
Error Ports
1
(ERR_PORTS) Ports with errors.
TABLE 113 Fabric measures
Measure Description
Domain ID changes (DID_CHG) Monitors forced domain ID changes. Forced domain ID changes occur when
there is a conflict of domain IDs in a single fabric and the principal switch
must assign another domain ID to a switch.
Fabric logins (FLOGI) Activates when ports and devices initialize with the fabric.
