Configuring The Allowed Maximum Number Of Dynamic Sessions; Configuring The Dscp Value For Ntp Messages - HP 5500 EI Series Configuration Manual

Step
1. Enter system view.
2. Enter Layer 3 Ethernet
interface view or VLAN
interface view.
3. Disable the interface from
receiving NTP messages.
Configuring the allowed maximum number of dynamic
sessions
NTP has the following types of associations:
Static association—An association that a user has manually created by using an NTP command.
•
• Dynamic association—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 period of time.
The following describes how an association is established in different operation modes:
• Client/server mode—After you specify an NTP server, the system creates a static association on the
client. The server simply responds passively upon the receipt of a message, rather than creating an
association (static or dynamic).
Symmetric active/passive mode—After you specify a symmetric-passive peer on a symmetric active
•
peer, static associations are created on the symmetric-active peer, and dynamic associations are
created on the symmetric-passive peer.
Broadcast or multicast mode—Static associations are created on the server, and dynamic
•
associations are created on the client.
A single device can have a maximum of 128 concurrent associations, including static associations and
dynamic associations.
To configure the allowed maximum number of dynamic sessions:
Step
1. Enter system view.
2. Configure the maximum
number of dynamic sessions
allowed to be established
locally.
