Chapter 4 Initial Configuration Tasks
For IDSM-2
•
–
Caution Be sure to set the time zone and summertime settings on both the switch and IDSM-2 to ensure that the
UTC time settings are correct. IDSM-2's local time could be incorrect if the time zone and/or
summertime settings do not match between IDSM-2 and the switch.
–
• For NM-CIDS
–
Be sure to set the time zone and summertime settings on both the parent router and NM-CIDS to ensure
Caution
that the UTC time settings are correct. NM-CIDS's local time could be incorrect if the time zone and/or
summertime settings do not match between NM-CIDS and the router.

The IDSM-2 can automatically synchronize its clock with the switch time. This is the default.
The UTC time is synchronized between the switch and the IDSM-2. The time zone and
Note
summertime settings are not synchronized between the switch and the IDSM-2.
Use NTP
You can configure IDSM-2 to get its time from an NTP time synchronization source. See
Configuring a Cisco Router to be an NTP Server, page
address, the NTP key ID, and the NTP key value. You can configure IDSM-2 to use NTP during
initialization or you can set up NTP through the CLI, IDM, or ASDM.
We recommend that you use an NTP time synchronization source.
Note
NM-CIDS can automatically synchronize its clock with the clock in the router chassis in which
it is installed (parent router). This is the default.
The UTC time is synchronized between the parent router and NM-CIDS. The time zone
Note
and summertime settings are not synchronized between the parent router and NM-CIDS.
Use NTP
You can configure NM-CIDS to get its time from an NTP time synchronization source, such as
a Cisco router other than the parent router. See
page 4-28. You will need the NTP server IP address, the NTP key ID, and the NTP key value.
You can configure NM-CIDS to use NTP during initialization or you can set up NTP through
the CLI, IDM, or ASDM.
We recommend that you use an NTP time synchronization source.
