Parameter
Meaning
Pkts Sent
Total number of NTP client and server packets sent by your
device.
Pkts Received
Total number of NTP client and server packets received by your
device.
Pkts Processed
The number of packets processed by NTP. NTP processes a
packet once it has determined that the packet is valid by checking
factors such as the packet’s authentication, format, access rights
and version.
Pkts current
version
The number of version 4 NTP packets received.
Pkts old version
The number of NTP packets received that are from an older
version, down to version 1, of NTP. NTP is compatible with these
versions and processes these packets.
Pkts unknown
version
The number of NTP packets received that are an earlier version
than version 1, or a higher version than version 4. NTP cannot
process these packets.
Pkts access denied
The number of NTP packets received that do not match any
access list statements in the NTP access-groups. NTP drops these
packets.
Pkts bad length
The number of NTP packets received that do not conform to the
standard packet length. NTP drops these packets.
Pkts bad auth
The number of NTP packets received that failed authentication.
NTP drops these packets. Packets can only fail authentication if
NTP authentication is enabled with the
ntp authenticate
command.
Pkts rate exceed
The number of packets dropped because the packet rate
exceeded its limits.
