Display status of the node's NTP client
Availability: This command is available to cluster administrators at the advanced privilege level.
Description
The cluster time-service ntp status show command displays the status of the associations between the cluster and external network time servers that use the Network Time Protocol (NTP).
Parameters
- {
[-fields <fieldname>,…] -
If you specify the
-fields <fieldname>, …parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify. - |
[-instance ]} -
If this parameter is specified, the command displays detailed information about all entries.
[-node {<nodename>|local}]- Node (privilege: advanced)-
If this parameter is specified, the command displays information related to associations on the specifed node.
[-server <text>]- NTP Server Host Name, IPv4 or IPv6 Address (privilege: advanced)-
If this parameter is specified, the command displays information about the associations related to the specified NTP server. The server should be specified as it is configured in the cluster time-service ntp server show command.
[-server-address <IP Address>]- Server IP Address (privilege: advanced)-
If this parameter is specified, the command displays information about the associations related to the NTP server with the specified IP address.
[-is-peer-reachable {true|false}]- Is Peer Reachable and Responding to Polls? (privilege: advanced)-
If this parameter is specified as
true, the command displays information about associations with the NTP servers that have been successfully polled. [-is-peer-selected {true|false}]- Is Peer Selected as Clock Source? (privilege: advanced)-
If this parameter is specified as
true, the command displays information about associations with the NTP servers that have been selected as the current clock source. [-selection-state <State of NTP Peer Selection>]- State of Server Selection (privilege: advanced)-
If this parameter is specified, the command displays information about associations with the specified selection state.
[-selection-state-text <text>]- Description of Server Selection State (privilege: advanced)-
If this parameter is specified, the command displays information about associations with the specified selection state description.
[-poll-interval <integer>]- Poll Interval (secs) (privilege: advanced)-
If this parameter is specified, the command displays information about associations that have the specified polling interval.
[-time-last-poll <integer>]- Time from Last Poll (secs) (privilege: advanced)-
If this parameter is specified, the command displays information about associations that are polled at the specified time.
[-offset <double hundredths>]- Offset from Server Time (ms) (privilege: advanced)-
If this parameter is specified, the command displays information about associations with the specified offset from the NTP server.
[-delay <double hundredths>]- Delay Time to Server (ms) (privilege: advanced)-
If this parameter is specified, the command displays information about associations with the specified travelling time to the NTP server.
[-jitter <double hundredths>]- Maximum Offset Error (ms) (privilege: advanced)-
If this parameter is specified, the command displays information about associations with the specified offset error from the NTP server.
[-reachability <Hex String>]- Reachability of Server (privilege: advanced)-
If this parameter is specified, the command displays information about associations with the specified reachability to the NTP server. Reachability is specified as a hexbyte that has a bit to represent the success of each of the last eight polls of the specified server. A set bit represents a successful poll. The least significant bit represents the most recent poll, the next most significant bit the poll before that, and so on.
[-server-stratum <integer>]- Stratum of Server Clock (privilege: advanced)-
If this parameter is specified, the command displays information about associations with NTP servers with the specified clock stratum.
[-server-reference <text>]- Reference Clock at Server (privilege: advanced)-
If this parameter is specified, the command displays information about associations with NTP servers using the specified clock as reference.
[-reported-errors <NTP Peer and Packet Errors>,…]- Reported Packet and Peer Errors (privilege: advanced)-
If this parameter is specified, the command displays information about associations with the specified errors.
Examples
The following example displays the status of the NTP associations of the cluster:
