vCenter Synchronization
When applying distributed VM group configuration changes, the switch will attempt to synchronize
settings with the VMware vCenter for virtualization management. If the vCenter is unavailable, an
error message will be displayed on the switch. Be sure to evaluate all error message and take the
appropriate actions to ensure the expected changes are properly applied. If corrective actions are not
taken, synchronization may remain incomplete when connection with the vCenter is restored.
Solution: When the switch connection with the vCenter is restored, use the following operational
command to force synchronization:
Daylight Saving Time
For the Asia/Israel time zone, BLADEOS sets the end of Daylight Saving Time (DST) as the last
week in September. However, because the observed end of DST varies according to the date of the
Yom Kippur holiday in the Hebrew calendar since 2005, occurring on various Saturdays in
September or October, the default DST rule may not work as desired.
For the Asia/Israel time zone, or any other time zone in which the start or end date of DST varies
from year to year, the administrator should create a custom DST rule for those years in which DST
is desired, but ends in a different week than the set by default.
Active MultiPath Protocol
For proper AMP operation, all access switches should be configured with a higher priority value
(lower precedence) than the aggregators. Otherwise, unexpected AMP keep-alive packets may be
forwarded from one aggregator switch to the other, even when its AMP group is disabled.
