I have what should be a simple issue, and I think I may be missing the basics. I am moving a internet circuit from one DC to another. The circuit currently terminates on an ASR 1002 IOSXE 03.06.00.S.
In preparation for the cut over I terminated the SMF (1-GBASE-LX/LH) on a Nexus 5548 to validate the cross connect and that I could ping across the /30 to the provider. This was working after forcing 1000/full and disabling auto neg. (XOs Ciena switch does not do auto neg. and this is forced on their side) here is the port config on the 5548.. The SVI in vlan 750 was in the /30 and could ping.
interface Ethernet1/18
no cdp enable
switchport access vlan 750
speed 1000
duplex full
no negotiate auto
I moved the ASR 1002 and moved the port to the ASR and nothing. Same port and provider we had before. I confirmed with XO that this is the port. And we are seeing correct light levels and polarity (see below.) XO confirms they are not learning a MAC on the Ciena switch but they see the correct light levels and I have called twice and they say all is good in the configuration on their side. I tried a different SFP and the same. I moved the cable back to the 5548 and it works.. The only difference I see is forcing the speed and duplex but this is not allowed on fiber ports on ASR to my knowledge. ARP is flushed on the XO side, and the 5548 was removed last night. /30 is correct. Any ideas here? I do not get ARP from the other side of the /30. I fell like this is basic and stupid but maybe someone can point something out. This ASR terminated another XO internet connection at the old DC for years on this port.
Thanks
