NTP Configuration
Network Time Protocol (NTP) synchronizes time among a set of distributed time servers and clients.
- NTP Overview
Network Time Protocol (NTP) is a protocol for synchronizing clocks on the network. - NTP Features Supported by the Device
The device supports basic NTP functions, local source interface for sending and receiving NTP packets, limit on the number of local dynamic sessions, and NTP access control. - Configuring Basic NTP Functions
You can configure basic NTP functions to enable devices on the network to synchronize clocks. - Configuring the Local Source Interface for Sending and Receiving
NTP Packets
You can configure a local source interface for sending and receiving NTP packets to prevent the IP addresses of other interfaces on the device becoming the destination address of a reply packet. This facilitates deployment of traffic control policies. - Limit on the Number of Local Dynamic Sessions
Excess dynamic sessions limit the number of static sessions. To address this problem, you can limit the number of dynamic sessions on the device. - Configuring NTP Access Control
On networks requiring high security, you can use NTP security functions to prevent malicious attacks from modifying NTP packets. - Maintaining NTP
In the maintenance of NTP, NTP packets are cleared, and the running status of NTP is monitored. - Configuration Examples
This topic provides configuration examples of NTP together with the configuration flowchart. The configuration examples explain networking requirements, configuration notes, and configuration roadmap.
