Operation
Disable the interface
from receiving NTP
packets
Display the session

CAUTION:
The source IP address in an NTP packet is the address of the sending interface
■
specified by the ntp-service unicast-server command or the ntp-service
unicast-peer command if you provide the address of the sending interface in
these two commands.
Dynamic connections can only be established when a switch operates in passive
■
peer mode, NTP broadcast client mode, or NTP multicast client mode. In other
modes, the connections established are static.
After the above configuration, you can execute the display command in any view to
display the running status of the NTP configuration, and verify the effect of the
configuration.
