GENEVE offloading is not required for the tunnel to come up. More than likely your MTU is not set high enough on the transport zone. It should be 1700 minimally and ideally much higher.
my MTU is at 1600 I increased to 1700 and the tunnel still doesn't come up. When I do a vmkping I get a message too long
This is on a UCS B-Class system and I have verified the MTU on the FI.
Please show your vmkping command and the output.
I found the issue. A logical network change was needed for the transport node vlan. Once that was done everything started to come up and communication started to flow.
Thx for the assistance!
May i ask what you have done to solve this issue, i have the same problem.
Also how should be the DPDK fastpath interface configuration ?
My issue were two:
1 - After I validated my MTU I started checking the logical config on the network
2 - I found that on the network all my uplinks to my FI (Running CISCO UCS) had all VLANs trunked
3 - Looking at the UCS I found that on the FI that my N-VDS Uplink did not have the transport VLAN applied to it
4 - I updated my Profile for the transport to include a transport VLAN as the default is 0 which is usually the native VLAN.
FastPath normally is supposed to be configured like this:
fp-eth0 - Overlay Network
fp-eth1 thru 2 - VLAN Network
