Tracks the number of times that an E_Port goes down. E_Ports
go down each time you remove a cable or SFP. SFP failures
also cause E_Ports to go down. E_Port downs may also be
caused by transient errors.
Indicates reconfigurations of the fabric. The following
occurrences can cause a fabric reconfiguration:
Two fabrics with the same domain ID have connected to
one another.
Two fabrics have joined.
An E_Port has gone offline.
A principal link has segmented from the fabric.
Indicates a Domain ID change. Domain ID changes occur
when there is a conflict of domain IDs in a single fabric and
the principal switch has to assign another domain ID to a
switch.
Tracks the cumulative number of segmentation changes.
Segmentation changes may occur due to
Zone conflicts.
Incompatible link parameters.
During E_Port initialization, ports exchange link parameters.
Incompatible parameters result in segmentation. This
incompatibility rarely occurs.
Domain conflicts.
Segmentation of the principal link between two switches.
Tracks number of zone changes. Keeps the user appraised on
how frequently they change zones. Because zoning is a
security provision, frequent zone changes probably mean a
security breach or weakness. Zone change messages occur
whenever there is a change in zone configurations.
Fabric login messages occur when ports/devices initialize
with the fabric.
Indicates whether the state of the SFP is normal or faulty, on
or off. A faulty or off state indicates that you must re-insert,
turn on, or replace the SFP.
