Anyone using NTP on an s8700 installation? I'd like to get some info about using this..

I do. Im still trying to figure out how often is sync's..

To setup the NTP. you have to use the web browser to the linux box. Update the Standy settings then interchange the servers and update the Standby again.

K- , thx. You had any issues during interchange? Any loss of dialtone or complaints of dropped calls. In other words, are you comfortable performing the process outside of a maintenance window?

No the interchange is done so fast you hardly ever see it.
I personally dont do any changes during working hours.
Yes I did take down a working PBX once, thats why :)

Funny thing is that changing the NTP on the offline is ok. However changing the gateway is not. It caused the StandBy to go active. Two active shelfs are not good. :)

Ive learned alot sense then hahaha

Another rule of thumb: Never make non-Definity changes to the ACTIVE server.

We were having modem problems at one cunstomer's site. Well, as a long time modem guy the first diagnostic technique that I employed was to reset/power cycle the modem. What no power cable? That shouldn't be a problem ... we'll just unplug the USB cable and plug it back in. BAD IDEA! Brought the server to its knees. There were a couple of spontaneous interchanges, all active calls remained up but no new dialtone was issued and no incoming calls were delivered until Linux finished investigating why one of its mounted devices disappeared and, "hey ... what's this new device that was just plugged into my USB port?" That took about 8-10 minutes and freaked out everyone on the site ... especially me.

Yeah ... lesson learned! <grin>

Wowsah. That's hard to believe - I mean, its a USB port, why not act like one. I need to move the LAN connection for one of my servers to another blade in our switch (add some redundancy). I thought I would just move the offline server, you know a quick pull-n-plug. Now I'm sceert.

You were freak out?... Just hear this crypt tale: same happen to me, but I swap both modems to check their correct operation. Deduce yourself what happen for the same 8-10 minutes!! Good to me not even the local AVAYA support knew why this happened until 3 weeks later by the TIER3 support guys. "Normal RH server behavior" they said. :confused:

GR3Tech: Did you figure out already how often sync's are? Please, let me know if you did. I have a request to change this sync time if it is possible.

Thanks in advanced,

I try to config the NTP server to S8700 already .... But seems the server only will sync the time with NTP server once time only after success to config the server .... any one know that how often will the S8700 sync will NTP server again ?

Thank you

I'd love to know how often this sync's. From what I can see it's not very often.
Our switch is normally about 2 minutes slower than the time on our PC's and the speaking clock and all our companies systems where applicable use the same NTP server.
However when installed they were the same time - gradually seemed to change!
