1Gig SFP in CCR1072

Thu Jan 31, 2019 5:53 pm

Having issues with 1Gig SFP's in the CCR1072 connecting down to CCR1036 devices. Specifically:

CCR1072-1G-8S+ running 6.43.8
CCR1036-12G-4S running 6.43.8

Upgraded recently in hopes this would help resolve, but it hasn't.

No errors observed in either direction, but will see OSPF neighbors drop across these point-to-point links. Have tried both auto-negotiation on both sides as well as hard coding 1Gig/Full-Duplex, same results. Even seeing basic traffic impairment while OSPF remains adjacent.

Anyone else seeing this, and have any suggestions on what I can try next?

Thank you.
