NTP Implementation
Mode Configuration
A switch can operate in the following NTP modes:
■
NTP client mode
■
NTP server mode
■
NTP peer mode
■
NTP broadcast server mode
■
NTP broadcast client mode
■
NTP multicast server mode
■
NTP multicast client mode
Prerequisites
When a Switch 7750 operates in NTP server mode or NTP peer mode, you need to
perform configuration on the client or the active peer only. When a Switch 7750
operates in NTP broadcast mode or NTP multicast mode, you need to perform
configurations on both the server side and the client side.
Configuring NTP
Implementation Modes
Broadcast mode
■
Configure the Switch 7750 to operate in NTP
broadcast server mode. In this case, the Switch
7750 broadcasts NTP packets through the
VLAN interface configured on the switch.
■
Configure the Switch 7750 to operate in NTP
broadcast client mode. In this case, the Switch
7750 receives broadcast NTP packets through
the VLAN interface configured on the switch.
Multicast mode
■
Configure the Switch 7750 to operate in NTP
multicast server mode. In this case, the Switch
7750 sends multicast NTP packets through the
VLAN interface configure on the switch.
■
Configure the Switch 7750 to operate in NTP
multicast client mode. In this case, the Switch
7750 receives multicast NTP packets through
the VLAN interface configure on the switch.
