Enabling NTP in Broadcast-Client Mode

Configure the switch in NTP broadcast-client mode if an NTP broadcast server, such as a router,
regularly broadcasts time-of-day information on the network. To compensate for any server-to-client
packet latency, you can specify an NTP broadcast delay (a time adjustment factor for the receiving of
broadcast packets by the switch).
To enable NTP broadcast-client mode on the switch, perform this task in privileged mode:
Task
Step 1 Enable NTP broadcast-client mode.
Step 2 (Optional) Set the estimated NTP broadcast
packet delay.
Step 3 Verify the NTP configuration.
This example shows how to enable NTP broadcast-client mode on the switch, set a broadcast delay of
4000 microseconds, and verify the configuration:
Console> (enable) set ntp broadcastclient enable
NTP Broadcast Client mode enabled
Console> (enable) set ntp broadcastdelay 4000
NTP Broadcast delay set to 4000 microseconds
Console> (enable) show ntp

Configuring NTP in Client Mode

Configure the switch in NTP client mode if you want the client switch to regularly send time-of day
requests to an NTP server. You can configure up to ten server addresses per client.
To configure the switch in NTP client mode, perform this task in privileged mode:
Task
Step 1 Configure the IP address of the NTP server.
Step 2 Enable NTP client mode.
Step 3
Verify the NTP configuration.
