Defect ID:
DEFECT000518620
Technical Severity:
High
Probability:
Medium
Product:
FOS
Technology:
Other
Reported In Release:
FOS7.2.1
Technology Area:
Other
Symptom:
Activation of the auto-tuning (serdestunemode --autoenable) on a switch that is also running MAPS
could result in the MAPS daemon to restart. HA Sync will be temporarily lost during this time for
each tuning value applied. Customer may see critical RASLOG errors such as [MAPS-1021] and
multiple [MAPS-1020]
Condition:
This happens when MAPS and auto-tuning are both enabled.
Workaround:
Contact Brocade support to disable MAPS prior to running auto-tuning.
Recovery:
If auto-tuning is already started, let auto-tuning to run to completion. Do not stop auto-tuning
prematurely and leave a sub-optimal value on the system, which could trigger blade fault.

FCIP
Symptom:
FCIP GigE portstatsshow frame TX type counters show inaccurate counts.
Condition:
This is seen when using the CLI command:
portstatsshow geX, where geX is ge1-ge5 on the 7800 platform

Technology:
FICON
Reported In Release:
FOS7.2.0
Technology Area:
FICON
Symptom:
Add ability to enable insistent domain ID (IDID) while the switch is online to permit non-disruptive
upgrade v7.2.x to v7.3.
Condition:
As per design, upgrade to from FOS7.2.x to FOS v7.3 is blocked if customer has single switch fabric
in FMS mode with SCC policy configured but IDID OFF. It requires a "switchdisable" in FOS v7.2.x
to set IDID ON.

Reported In Release:
FOS7.1.1
Technology Area:
Other

Defect ID:
DEFECT000525406
Technical Severity:
Medium
Probability:
Low
Product:
FOS
Technology:
Other
Reported In Release:
FOS7.0.0
Technology Area:
Other
Symptom:
When customers configure Edge Hold Time (EHT) in 16G switches running FOS v7.0.0, F-port and
E-port do not get expected values.
Condition:
It happens when a user makes EHT change on a 16G switch running FOSv7.0.0.
FOS v7.1, v7.2 and v7.3 do not have this problem. But upgrading to these releases does not
automatically correct the condition caused by FOS v7.0.0.
Recovery:
Upgrade to a release containing this fix, and re-run configure command to set the correct EHT values.
Alternatively, run slotpoweroff/on if the switch has already been upgraded to FOS v7.1 and above.
