Chapter 4 Turn Up Node

NTP-D25 Set Up Name, Date, Time, and Contact Information

Tip You can also position nodes manually on the network view map. Press Ctrl then drag and drop the node icon. To create a logical network map for all ONS 15454 SDH users, complete the “NTP-D172 Create a Logical Network Map” procedure on page 6-52 .

CTC uses the latitude and longitude to position ONS 15454 SDH icons on the network view map. To convert a coordinate in degrees to degrees and minutes, multiply the number after the decimal by

60. For example, the latitude 38.250739 converts to 38 degrees, 15 minutes (0.250739 x 60 = 15.0443, rounded to the nearest whole number).

•Description—Type a description of the node. The description can be a maximum of 255 characters.

•Use NTP/SNTP Server—When checked, CTC uses a Network Time Protocol (NTP) or Simple Network Time Protocol (SNTP) server to set the date and time of the node.

If you do not use an SNTP or NTP server, complete the Date and Time fields. The ONS 15454 SDH will use these fields for alarm dates and times. (CTC displays all alarms in the login node’s time zone for cross network consistency.)

Note Using an NTP or SNTP server ensures that all ONS 15454 SDH network nodes use the same date and time reference. The server synchronizes the node’s time after power outages or software upgrades.

If you check the Use NTP/SNTP Server check box, type the IP address of one of the following:

–an NTP/SNTP server connected to the ONS 15454 SDH

–Another ONS 15454 SDH with NTP/SNTP enabled that is connected to the ONS 15454 SDH

If you check gateway network element (GNE) for the ONS 15454 SDH proxy server, (see “DLP-D249 Provision IP Settings” task on page 4-10), external ONS 15454 SDH NEs must reference the gateway ONS 15454 SDH NE for NTP/SNTP timing. For more information about the proxy server feature, refer to the Cisco ONS 15454 SDH Reference Manual.

Caution If you reference another ONS 15454 SDH for the NTP/SNTP server, make sure the second

ONS 15454 SDH references an NTP/SNTP server and not the first ONS 15454 SDH (that is, do not create an NTP/SNTP timing loop by having two ONS 15454 SDH nodes reference each other).

•Date—If Use NTP/SNTP Server is not selected, type the current date in the format mm/dd/yyyy, for example, September 24, 2002 is 09/24/2002.

•Time—If Use NTP/SNTP Server is not selected, type the current time in the format hh:mm:ss, for example, 11:24:58. The ONS 15454 SDH uses a 24-hour clock, so 10:00 PM is entered as 22:00:00.

•Time Zone—Click the field and choose a city within your time zone from the drop-down menu. The menu displays the 80 World Time Zones from –11 through 0 (GMT) to +14. Continental United States time zones are GMT-05:00 (Eastern), GMT-06:00 (Central), GMT-07:00 (Mountain), and GMT-08:00 (Pacific).

Step 4 Click Apply.

Step 5 In the confirmation dialog box, click Yes.
