Limiting the Number of Local Dynamic NTP Sessions

Limiting the Number of Local Dynamic NTP Sessions


All configurations of basic NTP functions have been completed.


In both unicast client/server mode and symmetric peer mode, command lines are used to establish a connection, which is a static session. Dynamic sessions are established in broadcast mode, manycast mode and multicast mode, so that the limit on the number of local dynamic sessions takes effect.


The ntp max-dynamic-sessions command runs without affecting the existing NTP sessions. When the number of local dynamic NTP sessions exceeds the maximum number, a new session cannot be established.


  1. Run system-view

    The system view is displayed.

  2. Run ntp max-dynamic-sessions number

    The number of local dynamic sessions that can be established is configured.

    By default, a maximum of 100 NTP dynamic sessions can be established.

  3. Run commit

    The configuration is committed.

Verifying the Configuration

  • Run the display current-configuration | include ntp command to check the number of local dynamic sessions that can be established.
