enable ntp broadcast-server

enable ntp {vlan} vlan-name broadcast-server {key keyid}

An NTP broadcast server is enabled by default.

Usage Guidelines

For the broadcast server function to work correctly, configure a VLAN to forward broadcast packets by using the enable ipforwarding broadcast vlan-name command. All broadcast clients will receive clock information from the broadcasted clock messages.


The following command enables an NTP broadcast server on the switch:

enable ntp vlan toSW3 broadcast-server key 100
