If you have specified an interface in the ntp-service unicast-server or ntp-service unicast-peer

command, this interface will be used for sending NTP messages.

Configuring the Number of Dynamic Sessions Allowed on the Local Switch

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 server/client 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.
