AP Time Synchronization per Group

The APC can manage the time of APs per AP group based on two types of management
method, i.e. Time Stamp or NTP.
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.
Configuring Time Stamp type using CLI
1) Go to profile  time-config mode of configure  ap-group.
WEC8500# configure terminal
WEC8500/configure# ap-group apg_01
WEC8500/configure/ap-group apg_01# profile
WEC8500/configure/ap-group apg_01/profile# time-config
WEC8500/configure/ap-group apg_01/profile/time-config#
2) Configure how to transmit the time information to an AP using 'ac-stamp' and
configure the interval and timezone.

mode ac-stamp

ac-stamp-interval [INTERVAL]

timezone [TIMEZONE]
3) To check the time synchronization information per configured AP group, execute the
'show ap-group time-config' command.
