Configuring The Number Of Dynamic Sessions Allowed On The Local Switch; Disabling An Interface From Receiving Ntp Messages; Displaying Ntp Configuration - H3C S5600 Series Operation Manual

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.
Follow these steps to configure the number of dynamic sessions allowed on the local switch:
To do...
Enter system view
Configure the maximum number of
dynamic sessions that can be
established on the local switch
