We have a Telstra TID 50M/50M fibre link in Clayton that has worked fine since March but in the past 24 hours it’s become unusable except for 5 minutes bursts at random times.</div><div><br></div><div>All support says is the link is up. Until they finally admitted it is flapping, “we can’t help so need to escalate. Please leave a laptop connected and we’ll get someone to call you back. Beside it so you can help diagnose”.</div><div><br></div><div>I’ve already spent hours waiting for non-existent call backs. I don’t feel like spending another night on site waiting for a mystery call back. Though I will be hip all night on a different project so if any one has any ideas drop me an email or phone call 0407533109.</div><div><br></div><div>Network config is Telstra fibre > Cisco 3845 router > Netgear switch(s) </div><div><br></div><div>The network has public Telstra IP to Class C on Cisco router. No changes to config on router. Have tried swooping switches, even put TP-LINK Ethernet router in place of the Cisco to check if it was faulty. No luck, though the servers on our side of the Cisco do see the usual port scanning attempts.</div><div><br></div><div><br></div><div><br></div><div><br></div><div><div>Regards,</div><div><br></div><div><div>Chris Hurley </div><div><br></div><div>******************************************************</div><div>Dragon Rail Pty Ltd Phone: 1300 730 531 </div><div>74 Allanfield Crescent </div><div>Boronia, 3155 Victoria </div><div>Australia </div><div>******************************************************</div></div><div><br></div></div></body></html>
