Defect ID:
DEFECT000491192
Technical Severity:
Critical
Probability:
Medium
Product:
FOS
Technology:
Traffic Management
Reported In Release:
FOS7.2.0
Technology Area:
Routing
Closed In Release(s):
FOS7.2.1a(Fixed)
Symptom:
FOSv7.2.0, 7.2.0a, 7.2.0b, 7.2.0c, 7.2.1 with user defined logical switch, hosts may be unable to reach
targets due to frames being corrupted or traffic flow may appear to stop.
Condition:
This happens with customer configuration parameter “Custom.index" of 1,2,3,5, when user creates a
logical switch and then moves ports with non-default configuration to it. This can happen for both
FOSv7.1.x to FOSv7.2.x upgrade and with freshly installed FOSv7.2.x switches.
This does not happen with “Custom.index” of 0 or 4
Workaround:
Do not create or modify logical switch until upgrade to a code revision with fix.
Recovery:
Upgrade to a FOS release with the fix (v7.2.0d) will recover and also prevent future occurrence.
Downgrading from FOS 7.2.1 to a release with the fix (v7.2.0d) will not correct the problem and
v7.2.0d must be downloaded a second time after initial downgrade to v7.2.0d. Upgrade FOS7.2.1 to a
future 7.2.1a will address the problem. If a code upgrade is not possible, please use CLI
"portcfgdefault" on each port and then cold boot switch to recover.
