NTP Quick Steps
The following steps are designed to show the user the necessary commands to set up NTP on an OmniS-
witch:
1 Designate an NTP server for the switch using the ntp server command. The NTP server provides the
switch with its NTP time information. For example:
-> ntp server 198.206.181.139
2 Activate the client side of NTP on the switch using the ntp client command. For example:
-> ntp client admin-state enable
3 You can check the server status using the show ntp server status command, as shown:
-> show ntp server status 198.206.181.139
IP address = 198.206.181.139,
Host mode = client,
Peer mode = server,
Prefer = no,
Version = 4,
Key = 0,
Stratum = 2,
Minpoll = 6 (64 seconds),
Maxpoll = 10 (1024 seconds),
Delay = 0.016 seconds,
Offset = -180.232 seconds,
Dispersion = 7.945 seconds
Root distance = 0.026,
Precision = -14,
Reference IP = 209.81.9.7,
Status = configured : reachable : rejected,
Uptime count = 1742 seconds,
Reachability = 1,
Unreachable count = 0,
Stats reset count = 1680 seconds,
Packets sent = 1,
Packets received = 1,
Duplicate packets = 0,
Bogus origin = 0,
Bad authentication = 0,
Bad dispersion = 0,
Last Event = peer changed to reachable,
4 You can check the list of servers associated with this client using the show ntp client server-list
command, as shown:
-> show ntp client server-list
