Configuring Network Time Protocol (NTP) NTP Quick Steps NTP Quick Steps The following steps are designed to show the user the necessary commands to set up NTP on an OmniSwitch: 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 IP Address Ver Key St Delay Offset Disp ================+===+=======+====+==========+=================+========== 1.2.5.6 4 0 2 0.06 -0.673 0.017 OmniSwitch AOS Release 8 Switch Management Guide May 2014 page 11-3
