Create an NTP symmetric authentication key
Availability: This command is available to cluster administrators at the admin privilege level.
Description
The
cluster time-service ntp key create
command creates a cryptographic key that can be used to verify
that Network Time Protocol (NTP) packets are coming from a configured
NTP server.
To use the created key it must be
assigned to the required NTP server configuration using the
cluster time-service ntp server create or
cluster time-service ntp server modify commands.
Note: The id, key-type and value must all be configured identically
on both the ONTAP cluster and the external NTP time server for the
cluster to be able to synchronize time to that server.
Parameters
- -id <integer> - NTP Symmetric Authentication Key ID
- Uniquely identifies this key in the cluster.
Must be an integer between 1 and 65535.
- -type <sha1> - NTP Symmetric Authentication Key Type
- The cryptographic algorithm that this key is used with.
Only SHA1 is currently supported.
- -value <text> - NTP Symmetric Authentication Key Value
- A 40 character hexadecimal digit string that represents a
cryptographic key that is shared with the NTP server.
Examples
The following example creates a new SHA-1 NTP symmetric
authentication key.
