I have a CCR1036-12G-4S (ROS 6.23 BL 3.20) as my edge router. Actually using it as a switch right now but planning to migrate the duties of my 386 based unit (ROS 4.16) over to this to save power and eliminate moving parts.
My Metro Ethernet comes in on multimode fiber and we purchased this card to allow us to connect it to the 386 based box. http://www.alliedtelesis.com/media/data ... 1sx_ds.pdf
It has worked great but it is time to update. I have tried twice to move this fiber circuit over to the CCR but have been unable to get it to work.
Yesterday I was thrown off track for several hours by the bug where the CCR's LED assignments get boogered and the LEDs for all SFP ports were flashing. The forum helped a lot with finding that. They somehow were mapped to ETH1.
So anyway, I did all the normal tests on my fiber jumpers, swapping SFPs etc (I tried a Dell one and a Transition Networks one).
I even had the crew at the data center go over all the patch cables involved with getting me over to the demarcation of the fiber (a Ciena layer 3 switch) just in case. All looked fine. I could never even get the CCR to say the link was up until I turned off auto-negotiation.
After that, the link came up and I saw received traffic on the interface. But never saw more than 3 transmit packet attempts.
Plugged fiber back to the 386 unit and things worked fine. Back to the CCR- Nothing. I did try several setting changes on the SFP port but nothing worked any better. I did make sure the SFP port was added to the bridge with the Ethernet ports and I did try all 4 SFP ports.
We are all stumped. Does anyone have any suggestions? Shouldn't fiber "just work", especially if it is just moving from one MT to another?
I have checked the release notes for all firmware loads and can't find anything about the SFP port at all.
