WEC8050 / WEC8500 Operation Manual
4.2.3 AP Time Synchronization per Group
The AP can configure its time information using either the time stamp method or the NTP
method.
In the Time Stamp type, the APC periodically transmits the time of APC to an AP and the
AP is operating based on the received time. Unless a user changes the configuration, the
default is Time Stamp type and the interval is set to 7200 seconds (2 hours).
In the NTP type, the NTP server information is transmitted to an AP and the AP
synchronizes the time with the NTP server. A NTP server list must be created to transmit
the NTP server information to an AP and maximum 10 lists can be added. The ntp-interval
(2^N) is the interval when an AP receives the time information from the NTP server.
For example, if the ntp-interval is set to 6, an AP receives the time information from the
NTP server at every 2^6, i.e. 128 seconds.
The APC provides a function for configuring the time configuration method of the AP.
Configuring Time Stamp type using CLI
1) Go to configure  apc  ap-time-config configuration mode of CLI.
WEC8500# configure terminal
WEC8500/configure# apc
WEC8500/configure/apc# ap-time-config
WEC8500/configure/apc/ap-time-config#
2) Configure how to transmit the time information to an AP using 'ac-stamp' and
configure the interval.

mode ac-stamp

ac-stamp-interval [INTERVAL]
3) To check the information, execute the 'show apc ap-time-config' command.
Configuring NTP type using CLI
1) Go to configure  apc  ap-time-config configuration mode of CLI.
WEC8500# configure terminal
WEC8500/configure# apc
WEC8500/configure/apc# ap-time-config
WEC8500/configure/apc/ap-time-config#
2) Add the NTP server information to transmit to an AP. Maximum 10 NTP server
information can be added. To delete the configured NTP server information, enter 'no'
parameter in front of the command
