Quidway S6500 Series Ethernet Switches
[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
# Set Quidway1 as time server.
[Quidway2[ ntp-service unicast-server 1.0.1.11
# Enable authentication.
[Quidway2] ntp-service authentication enable
# Set the key.
[Quidway2] ntp-service authentication-keyid 42 authentication-mode md5 aNiceKey
# Set the key as reliable.
[Quidway2] ntp-service reliable authentication-keyid 42
[Qudiway2] ntp-service unicast-server 1.0.1.11 authentication-keyid 42
The above examples synchronized Quidway2 by Quidway1. Since Quidway1 has not
been enabled authentication, it cannot synchronize Quidway2. And now let us do the
following additional configurations on Quidway1 :
# Enable authentication.
