Not sure if this is the proper place to ask this, but in the logs on one of my Catalyst 3560 switches that we are using for VLAN routing, I get an NTP PEER Unreachable, but for an IP Adress that isn't configured on the switch. Any ideas how/why I get this?
Here's the error message:
005925: .Sep 4 14:37:47.352: %NTP-4-PEERUNREACH: Peer 192.168.4.124 is unreachable 005926: .Sep 4 14:39:09.349: %NTP-4-PEERUNREACH: Peer 192.168.4.125 is unreachable 005927: .Sep 4 15:30:13.740: %NTP-6-PEERREACH: Peer 192.168.4.124 is reachable 005928: .Sep 4 15:31:27.667: %NTP-6-PEERREACH: Peer 192.168.4.125 is reachable
Both 124 and 125 are used on 2 windows NT servers running in VMs (VirtualBox) on a Ubuntu server.
Here's what is in the running config pertaining to NTP:
To resolve this issue you might have to remove theNTP configuration and reconfigured the same.
Second to findout the root cause:
Okay, what are those servers? It seems they broadcast such request and these routers are responding to it, can we pick one server look at it config and see if that is really the case?
Because routers with NTP logging enabled simply notifying of the event it may not TRIGGERING that event is what I am after.
I think it's normal operational behavior that NTP syncs with external servers occasionally when the assign one flapped or re-sync during that time.
**********Plz rate if this info is helpfull**********
With which server is the switch being sync??? And Regarding 124 and 125 server as told by Sharieff there might be any kind of updates being triggered from the Server so for the confirmation is it possible to shutdown the server and check if the error exist or not....??
