Parameters
number : Maximum number of dynamic NTP sessions that are allowed to be established, in the range
of 0 to 100.
Description
Use the ntp-service max-dynamic-sessions command to set the maximum number of dynamic NTP
sessions that are allowed to be established locally.
Use the undo ntp-service max-dynamic-sessions command to restore the maximum number of
dynamic NTP sessions to the system default.
By default, the number is 100.
A single device can have a maximum of 128 associations at the same time, including static
associations and dynamic associations. A static association refers to an association that a user has
manually created by using an NTP command, while a dynamic association is a temporary association
created by the system during operation. A dynamic association will be removed if the system fails to
receive messages from it over a specific long time. In the client/server mode, for example, when you
carry out a command to synchronize the time to a server, the system will create a static association,
and the server will just respond passively upon the receipt of a message, rather than creating an
association (static or dynamic). In the symmetric mode, static associations will be created at the
symmetric-active peer side, and dynamic associations will be created at the symmetric-passive peer
side; in the broadcast or multicast mode, static associations will be created at the server side, and
dynamic associations will be created at the client side.
