Quidway S3500 Series Ethernet Switches
Configure Ethernet Switch Quidway4:
# Enter system view.
<Quidway4> system-view
# Enter Vlan-interface2 view.
[Quidway4] interface vlan-interface 2
# Enable multicast client mode.
[Quidway4-Vlan-Interface2] ntp-service multicast-client
Configure Ethernet Switch Quidway1:
# Enter system view.
<Quidway1> system-view
# Enter Vlan-interface2 view.
[Quidway1] interface vlan-interface 2
# Enable multicast client mode.
[Quidway1-Vlan-Interface2] ntp-service multicast-client
The above examples configure Quidway4 and Quidway1 to receive multicast
messages from Vlan-interface2, Quidway3 multicast messages from Vlan-interface2.
Since Quidway1 and Quidway3 are not located on the same segments, Quidway1
cannot receive the multicast packets from Quidway3, while Quidway4 is synchronized
by Quidway3 after receiving the multicast packet.
V. Configure authentication-enabled NTP server mode
1) Network requirements
Quidway1 sets the local clock as the NTP master clock at stratum 2. Quidway2 sets
Quidway1 as its time server in server mode and itself in client mode and enables
authentication.
2) Networking diagram
See Figure 7-2.
3) Configuration procedure
Configure Ethernet Switch Quidway1:
# Enter system view.
<Quidway1> system-view
# Set the local clock as the master NTP clock at stratum 2.
[Quidway1] ntp-service refclcok-master 2
Configure Ethernet Switch Quidway2:
# Enter system view.
<Quidway2> system-view
