Hello, I'm not sure if this is the right place to ask a question like it, but I thought I would try... I have a 2821 at a Colocation in a cabinet that my company is renting from a telco. Two times last month our internet connection went down there and what ultimetly brought us back online was physically unplugging us from the telco's switch and plugging it back in. The telco's tech tried to reboot/reset the switch port and even that didn't work, the only thing that fixed it was physically unplugging/replugging. Now the telco is blaming my equipment, saying that something with my router must be causing the problem with the switch port. During an outage I tried everything on my side that I could (rebooting router, unplugging/replugging on my side, etc) but as I said the only thing that fixed the problem is physical unplugging/replugging on the telco's switch. I checked out the log and during the outage it did show the interface as going up and down: 000130: *Dec 9 14:12:24.319 PCTime: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/0, changed state to up 000131: *Dec 9 14:12:34.319 PCTime: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/0, changed state to down 000132: *Dec 9 14:13:04.319 PCTime: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/0, changed state to up 000133: *Dec 9 14:13:14.319 PCTime: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/0, changed state to down 000134: *Dec 9 14:13:34.319 PCTime: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/0, changed state to up 000135: *Dec 9 14:13:44.319 PCTime: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/0, changed state to down The telco's techs are blaming my router and I'm wondering if it makes any sense that a router could mess up a switch port until it it physically unplugged? Is there any kind of diagnostics I can run on my router to prove that my equipment is good? Thanks!
