Security Violations category parameters (Continued) TABLE 8
Monitored parameter Description
TS out of sync (SEC_TS) Time Server (TS) violations, which occur when an out-of-synchronization error
has been detected.
Fabric State Changes
The Fabric State Changes category contains areas of potential inter-device problems, such as zone
changes, fabric segmentation, E_Port down, fabric reconfiguration, domain ID changes, and fabric
logins.
The following table below lists all the monitored parameters in this category.
Fabric State Changes category parameters TABLE 9
Monitored parameter Description
Domain ID changes
(DID_CHG) Monitors forced domain ID changes. These 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.
Fabric reconfigurations
(FAB_CFG) Tracks the number of fabric reconfigurations. These occur when the following
events happen:
• Two fabrics with the same domain ID are connected
• Two fabrics are joined
• An E_Port or VE_Port goes offline
• A principal link segments from the fabric
E_Port downs
(EPORT_DOWN) Tracks the number of times that an E_Port or VE_Port goes down. E_Ports and
VE_Ports go down each time you remove a cable or an SFP transceiver (where
there are SFP transceiver failures or transient errors).
Segmentation changes
(FAB_SEG) Tracks the cumulative number of segmentation changes. Segmentation changes
occur because of one of the following events occurs:
• Zone conflicts
• Domain conflicts
• Incompatible link parameters
During E_Port and VE_Port initialization, ports exchange link parameters, and
incompatible parameters (uncommon) result in segmentation.
• Segmentation of the principal link between two switches
Zone changes (ZONE_CHG) Tracks the number of zone changes. Because zoning is a security provision,
frequent zone changes may indicate a security breach or weakness. Zone change
messages occur whenever there is a change in zone configurations.
Percentage of devices in a
Layer 2 fabric
(L2_DEVCNT_PER) Monitors the percentage of imported devices in a Fibre Channel fabric relative to
the total number of devices supported in the fabric, whether they are active or not.
The switches in a pure Layer 2 fabric do not participate in the metaSAN.
