VxLAN on N9Kv traffic issue

Post by snurfit » Sun Mar 25, 2018 1:13 pm

Hi Guys,

I have tried creating a simple Leaf-Spine-Leaf setup as per different users. All the control plane information checks out and im learning Mac addresses and all that, but I simply can't get traffic from hosts (tried both windows and linux machines as well as CSR routers as clients) going through. Anyone of you guys which have setup these labs run into any issues?

It goes as far as having the ARP requests sent through the fabric and toward the other VTEP, but its not being sent out the access-link.

Appreciate any help!

Thanks!

Known issue, Cisco has locked RFC MAC on NX

Add this stuff to NXOS and see how it works then :)

Thank you..

But this is only for LACP towards the hosts right? I couldn't see anything in the thread about the MAC issue?

Im not running LACP toward the end hosts... Straight access ports.

Thanks again UD.

not observed such issues straight connection is ok

Remember that CSR has demo lic on board limited to 100Kb throughput speed...this can be issue of slowness
