Be sure to set the time zone and summertime settings on both the parent router
and the NM-CIDS to ensure that the GMT time settings are correct. The
NM-CIDS's local time will be incorrect if the timezone and/or summertime
settings do not match between the NM-CIDS and the router.
–
Use NTP.
You can configure your NM-CIDS to get its time from an NTP time
synchronization source, such as a Cisco router other than the parent router.
See
Configuring a Cisco Router to be an NTP Server, page
need the NTP server IP address, the NTP key ID, and the NTP key value. You
can configure the NM-CIDS to use NTP during initialization or you can set
up NTP later. See
Source, page
10-21, for more information.
We recommend that you use an NTP time synchronization source.
