Fabric reconfigurations (FAB_CFG) Tracks the number of reconfigurations of the fabric. Fabric reconfiguration
occurs when:
•
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.
Down E_Port (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:
•
Zone conflicts.
•
Incompatible link parameters. During E_Port and VE_Port initialization,
ports exchange link parameters, and incompatible parameters result in
segmentation. This is a rare event.
•
Domain conflicts.
•
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 might indicate a security breach or weakness. Zone
change messages occur whenever there is a change in zone configurations.
L2_DEVCNT_PER
Tracks the number of device connections in Layer 2 fabrics. The maximum
supported limits in Layer 2 fabrics are the following:
•
4096 for all platforms supported by Fabric OS v7.0.x
•
6000 for fabrics with the following platforms:
-
Brocade DCX
-
Brocade DCX-4S
-
Brocade DCX-8510
-
Brocade 6520
-
Brocade 6510
-
Brocade 6505
-
Brocade 5300
-
Brocade 5100
-
Brocade 300
-
Brocade 7800
-
Encryption switch
LSAN_DEVCNT_PER
Tracks the maximum number of imported LSAN devices per the total number
of devices imported from all the edge fabrics. The maximum supported limits
are the following:
•
1000 with the following devices:
-
Brocade DCX
-
Brocade DCX-4S
-
Brocade DCX 8510-8
-
Brocade DCX 8510-4
•
5000 with the following devices:
-
Brocade 5300
-
Brocade 5100
-
Brocade 300
-
Brocade 7800
-
Brocade 6520
-
Brocade 6510
