Concept Guide

Field Description
• + means the peer was selected for possible synchronization.
• - means the peer is a candidate for selection.
• x means designated falsesticker by the intersection algorithm.
remote Displays the remote IP address of the NTP peer.
ref clock Displays the IP address of the remote peer’s reference clock.
st Displays the peer’s stratum, that is, the number of hops away from the external time source. A
16 in this column means the NTP peer cannot reach the time source.
when Displays the last time the switch received an NTP packet.
poll Displays the polling interval (in seconds).
reach Displays the reachability to the peer (in octal bitstream).
delay Displays the time interval or delay for a packet to complete a round-trip to the NTP time source
(in milliseconds).
oset Displays the relative time of the NTP peer’s clock to the switch clock (in milliseconds).
disp Displays the dispersion.
