NTP implementation mode
Configuration on S5600 switches
Client/Server mode
Configure the S5600 switch to operate in the NTP
server mode. In this case, the remote server
operates as the local time server, and the S5600
switch operates as the client.
Peer mode
Configure the S5600 switch to operate in NTP peer
mode. In this case, the remote server operates as
the peer of the S5600 switch, and the S5600 switch
operates as the active peer.
Broadcast mode
z
Configure the S5600 switch to operate in NTP
broadcast server mode. In this case, the S5600
switch broadcast NTP packets through the VLAN
interface configured on the switch.
z
Configure the S5600 switch to operate in NTP
broadcast client mode. In this case, the S5600
switch receives broadcast NTP packets through
the VLAN interface configured on the switch.
Multicast mode
z
Configure the S5600 to operate in NTP multicast
server mode. In this case, the S5600 switch
sends multicast NTP packets through the VLAN
interface configure on the switch.
z
Configure the S5600 switch to operate in NTP
multicast client mode. In this case, the S5600
switch receives multicast NTP packets through
the VLAN interface configure on the switch.
1.2 NTP Implementation Mode Configuration
A switch can operate in the following NTP modes:
z
NTP client mode
z
NTP server mode
z
NTP peer mode
z
NTP broadcast server mode
z
NTP broadcast client mode
z
NTP multicast server mode
z
NTP multicast client mode
1.2.1 Prerequisites
When an S5600 switch operates in NTP server mode or NTP peer mode, you need to
perform configuration on the client or the active peer only. When an S5600 switch
operates in NTP broadcast mode or NTP multicast mode, you need to perform
configurations on both the server side and the client side.
