NI Module Behavior During Takeover

If there are no unsaved configuration changes and the flash directories on both the primary and secondary

management modules have been synchronized through the copy flash-synchro command, no NIs is

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 (for example, a VLAN is configured on

several different interfaces) and the changes are not saved through the write memory command, the

corresponding NIs automatically reloads if a management module takeover occurs. Data flow on the

affected NIs will be interrupted until the reload is complete. Note that the NIs reloads whether the flash

synchronization status shows SYNCHRONIZED. This is because the unsaved changes have occurred in

the running configuration ( RAM), and have not been written to the configuration file of the flash direc-

tory. In this case, a list of only the affected NIs is displayed in the table output (for example, 1 6).

If the flash directories on the primary and secondary management modules are not synchronized (for

example, a copy flash-synchro command has not been issued recently), all NIs is reloaded automatically

if a management module takeover occurs. Data flow is interrupted on all NIs until the reload is complete.
