Usage guidelines
A single device can have a maximum of 128 concurrent associations, 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 is removed if the system fails to receive messages from it over
a specific long time. In client/server mode, for example, when you carry out a command to synchronize
the time to a server, the system creates a static association, and the server just responds passively upon
the receipt of a message, rather than creating an association (static or dynamic). In symmetric mode,
static associations are created at the symmetric-active peer side, and dynamic associations are created
at the symmetric-passive peer side. In broadcast or multicast mode, static associations are created at the
server side, and dynamic associations are created at the client side.
Examples
# Set the maximum number of dynamic NTP sessions allowed to be established to 50.
