key ID keyid ranges from 0 to 4294967295; ttl-number of the multicast packets ranges
from 1 to 255; And the multicast IP address defaults to 224.0.1.1.
This command can only be configured on the interface where the NTP multicast packet
will be transmitted.
VI. Configure NTP Multicast Client Mode
Designate an interface on the local Ethernet Switch to receive NTP multicast messages
and operate in multicast client mode. The local Ethernet Switch listens to the multicast
from the server. When it receives the first multicast packets, it starts a brief client/server
mode to switch messages with a remote server for estimating the network delay.
Thereafter, the local Ethernet Switch enters multicast client mode and continues
listening to the multicast and synchronizes the local clock by the arrived multicast
message.
Perform the following configurations in VLAN interface view.
Table 7-6 Configure NTP multicast client mode
Operation Command
Configure NTP multicast client mode ntp-service multicast-client [ ip-address ]

Multicast IP address ip-address defaults to 224.0.1.1; This command can only be
configured on the interface where the NTP multicast packets will be received.
7.2.2 Configure NTP ID Authentication
Enable NTP authentication, set MD5 authentication key, and specify the reliable key. A
client will synchronize itself by a server only if the serve can provide a reliable key.
