Network Time Protocol (NTP) Sources
Introduction
This chapter includes the following information on managing a Traverse network:
• NTP Sources in a Traverse Network
• NTP Sources on a Ring Topology
• NTP Sources on a Linear Chain Topology

in a Traverse
Network
Network Time Protocol provides an accurate time of day stamp for performance
monitoring and alarm and event logs. Force10 recommends using the TransNav
management system server as the primary NTP source if you do not already have a
NTP source defined. If no primary NTP source is configured, the TransNav system
defaults to the TransNav server as the primary NTP source. A secondary NTP IP server
address is optional. If a node is reset, the time stamps on alarms that are generated after
the reset occurs will display the time that the node was reset.
Depending on the topology, configure a primary NTP source and a secondary NTP
source for each node in a network.
• For ring topologies, see NTP Sources on a Ring Topology.
• For linear chain topologies, see NTP Sources on a Linear Chain Topology.
Daylight Saving Time
As part of a United States federal energy conservation effort, Daylight Saving Time
(DST) starts three weeks earlier and ends one week later than in years prior to 2007.
Certain telecommunications products contain the ability to synchronize to a network
clock or automatically change their time stamp to reflect time changes. Each device
may handle the recent change in DST differently.
All dates displayed in the TransNav management system CLI for alarms, upgrade
times, events, and performance monitoring (PM) includes the new DST. The
TraverseEdge 100 system CLI also includes the new DST.
