Chapter 5 Administering the Access Point
Managing the System Time and Date
Beginning in privileged EXEC mode, follow these steps to configure the access point to receive NTP
broadcast packets from connected peers:
To disable an interface from receiving NTP broadcast packets, use the no ntp broadcast client interface
configuration command. To change the estimated round-trip delay to the default, use the no ntp
broadcastdelay global configuration command.
This example shows how to configure an interface to receive NTP broadcast packets:
AP(config)# interface gigabitethernet0/1
AP(config-if)# ntp broadcast client
Configuring NTP Access Restrictions
You can control NTP access on two levels as described in these sections:
• Creating an Access Group and Assigning a Basic IP Access List, page 5-30
• Disabling NTP Services on a Specific Interface, page 5-31
