Defect ID:
DEFECT000512057
Technical Severity:
Medium
Probability:
High
Product:
FOS
Technology:
Monitoring/RAS
Reported In Release:
FOS7.2.0
Technology Area:
Fabric Watch
Symptom:
Error messages start after firmware update from FOS v7.0.x to FOS v7.1.x and continue when
upgrading to FOS v7.2.x. After downgrading back to 7.0.x, faulty port messages stop from Fabric
Watch.
Condition:
Running FOS 7.1 and above, with a port remains in passive mode, which would simply complete
speed negotiation and failing link init, results in FW-xxxx flood in RAS log.
Workaround:
Disable the port that does not cut off light

Reported In Release:
FOS7.2.0
Technology Area:
Routing
Symptom:
Observed performance issue on FX8-24 when there are exactly two equal bandwidth FCIP tunnels.
Condition:
Only applicable when there are two incoming paths (E-ports, trunks, EX-ports) on a given FX8-24 or
BR7800 ASIC Chip.
Workaround:
Use one or greater than two incoming path to FX8-24 and 7800, or configure one of the links with
a slightly lower bandwidth.

Technology:
Virtualization
Reported In Release:
FOS7.2.0
Technology Area:
Access Gateway
Symptom:
ELS commands get rejected and host on AG switch can no longer communicate with the target in the
3rd party vendor fabric.
Condition:
This may happen in a Fabric with Access Gateway F-port with at least one NPIV login, and one of the
NPIV logins has a PID with the domain and area portion equal to that of the target.
Workaround:
Reconfigure the fabric switch so that the domain and area portions of PIDs on Access Gateway F-
ports do not match the domain and area portions of the target's PID.
Recovery:
Reboot the Access Gateway switch.
