OS10(config)# ntp source ethernet 1/1/24
Supported
Releases
10.2.0E or later
ntp trusted-key
Sets a key to authenticate the system to which NTP synchronizes with.
Syntax
ntp trusted-key number
Parameters number — Enter the trusted key ID (1 to 4294967295).
Default Not configured
Command Mode CONFIGURATION
Usage
Information
The number parameter must be the same number as the number parameter in the ntp
authentication-key command. If you change the ntp authentication-key command, you
must also change this command. The no version of this command removes the key.
Example
OS10(config)# ntp trusted-key 234567

Information
● (none) — One or more of the following symbols displays:
○ * — Synchronized to this peer.
○ # — Almost synchronized to this peer.
○ + — Peer was selected for possible synchronization.
○ - — Peer is a candidate for selection.
○ ~ — Peer is statically configured.
● remote — Remote IP address of the NTP peer.
● ref clock — IP address of the remote peer’s reference clock.
● st — Peer stratum (number of hops away from the external time source). 16 means that the NTP
peer cannot reach the time source.
●
when — Last time the device received an NTP packet.
● poll — Polling interval (in seconds).
● reach — Reachability to the peer (in octal bitstream).
● delay — Time interval or delay for a packet to complete a round-trip to the NTP time source (in
milliseconds).
● offset — Relative time of the NTP peer’s clock to the network device clock (in milliseconds).
● disp — Dispersion.
