Alarm Round trip violation etc

Alarm Round trip violation etc

Alarm Round trip violation etc

(OP)
Hi,

I get often in my Alarms this kind of event...

information 2018-08-26T15:33:25.634487 BCM450V60 utps [7785]: eventID=50507; message=Round Trip Delay Violation Cleared: 9ms, nearDN: 314, source IP: 192.168.2.30, source port: 51008, destination IP: 174.88.230.71, destination port: 30096, ct 0, eT D, nLR 62, dR 70, bD 138, bL 291710, gD 76, gL 26475, eSD 56, aNL 0, aSP 0, rTT 647; problemResolution=No Action Required.

I don't see any problems physicaly or software, there is no phones laggy quality is very fine, the main switch is a Rosewill 1000Mbps, i never noticed a conjested sign on my network, still always have in lan <10 ms.


what i need to do with this ?
It's annoying to see this on almost all set when they took the handset.

RE: Alarm Round trip violation etc

I have always blamed one of my cheap TPlink local switches for the 3 phones on it, others are ok.

Try going into TelephonyMetrics/PVQM and adjust some of the settings there.

Mine are setup as:
Inter 20/40/20/40
Listening 65/0/65/0
PacketLoss 2/7/2/7
RoundTrip 120/120/120/100 <----start with this one

Polling Default at 10

Been awhile since I played with this section but did manage to reduce the alarms.
It's like setting the threshold as when to trigger an alarm.

Done ! Thanks ! :)

You are right, the main router is a TP-Link TL-ER604W, but phones technicaly don't need to deal with, the rosewill switch is suppose to do the routing and the DHCP server is a win2k3, the tp-link is supplying the internet only, this is strange ! But i will not be surprise that router is bugging the whole network packets, i had already many problems with that router in past.

Yes as Curly has stated, it is a pain. What I do now is to reduce the events in the Alarm manager section.
