[AusNOG] Megaport - Link Negotiation

Hi Guys,

this is not relevant to the Megaport part, but I can say that I have actually seen 10G optic in a 10G switch port auto-negotiated on 1G-full duplex and the service was up and running. I can’t say if this setup would be causing any issues or not, but the optic was Smartoptics SO-SFP-10GE-SR .Later on we have changed speed to 10G-full duplex and it was running 10G.

Thank you
Jiri

Dear All

If you have a Single mode 10gbit SFP+ (used in say a Brocade MLXe router, like what Megaport use)

And plug this into a 1gbit SFP single mode (at the other end, i.e. your equipment) the service will connect and work at 1gbit perfectly ;-)

Kindest Regards

Are you asking if its possible, or have you noticed a fault where your current connection has negotiated down to 1gbps?

Hi AUSNOG,

I am wondering if anyone peering with Megaport has negotiated down to Gigabit on their inter-connect?

Thanks

Dylan.
