HP ProCurve 9304M Installation And Configuration Manual page 83

• Running-config – The running-config is automatically copied from the active redundant management module
to the standby redundant management module at regular intervals. The default interval is 10 seconds. You
can change the interval to 4 – 20 seconds. If you set the interval to 0, the configuration data is not copied to
the standby redundant management module. As described above, if switchover occurs, the standby
redundant management module loads system parameters from the running-config that was last received from
the active redundant management module.
Figure 3.1 shows how the files are synchronized between the active redundant management module and the
standby redundant management module.
