NI Module Behavior During Takeover
In OmniSwitch 9000 switches only, if there are no unsaved configuration changes and the flash directo-
ries on both the primary and secondary management modules have been synchronized via the
copy flash-synchro command, no NIs will be reloaded if a management module takeover occurs. As a
result, data flow is not interrupted on the NIs during the takeover.
If a configuration change is made to one or more NI modules (e.g., a VLAN is configured on several
different interfaces) and the changes are not saved via the write memory command, the corresponding
NIs will automatically reload if a management module takeover occurs. Data flow on the affected NIs will
be interrupted until the reload is complete. Note that the NIs will reload whether or not the flash synchro-
nization status shows SYNCHRONIZED. This is because the unsaved changes have occurred in the
running configuration (i.e., RAM), and have not been written to the flash directory’s configuration file. In
this case, a list of only the affected NIs is displayed in the table output (e.g., 1 6).
If the flash directories on the primary and secondary management modules are not synchronized (e.g., a
copy flash-synchro command has not been issued recently), all NIs will be reloaded automatically if a
management module takeover occurs. Data flow will be interrupted on all NIs until the reload is complete.
