display ntp-service statistics packet

Function

The display ntp-service statistics packet command displays statistics about global NTP packets.

Format

display ntp-service statistics packet [ ipv6 ]

display ntp-service statistics packet [ ipv6 ] interface { ifname | interface_type interface_num | all }

display ntp-service statistics packet peer [ [ ipv4Addr [ vpn-instance vpnName ] ] | ipv6 [ ipv6Addr [ vpn-instance vpnName ] ] ]

Parameters

Parameter	Description	Value
ipv6 ipv6Addr	Displays NTP packet statistics on a specified IPv6 peer.	The address is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
interface ifname	Interface name.	-
interface interface_type	Interface type.	-
interface interface_num	Interface number.	-
all	Displays the packet statistics on all interfaces.	-
peer	Displays packet statistics on IPv4 peers.	-
ipv4Addr	Displays NTP packet statistics on a specified IPv4 peer.	The value is an IPv4 address in dotted decimal notation.
vpn-instance vpnName	Specifies the name of a VPN instance associated with the NTP peer.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported.
