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 congured
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
Supported Releases 10.2.0E or later
show ntp associations
Displays the NTP master and peers.
Syntax
show ntp associations [vrf management]
Parameters None
Default Not congured
Command Mode EXEC
Usage 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 congured.
• 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.
