TNSR newbie

montenegro

having trouble with my first TNSR lab... i believe i have interfaces setup correctly, but locally connected devices do not receive ARP replies, yet neighbors exist? i am confused... not really sure where i might have messed up or what i missed. but cannot get neighbor unless i ping from directly connected host - not from ping-out from tnsr dataplane

@montenegro This generally works no problem. Are you using a virtual environment or something of that nature?

montenegro

Yes -- it is running on hyper-v/windows 2019

@montenegro

We have not yet confirmed that Hyper-V is a viable platform.

You can try running this in the shell:

dnf update
reboot

sudo tnsrctl stop
sudo modprobe uio_hv_generic
sudo tnsrctl start

Then try adding the NICs to the dataplane.

Adding the module to

/etc/modules.load.d/

Would be a persistent solution.

If you can, capture the output of all of this and post it if it does not work.

@derelict dnf update failed with a certificate error, probably because this is a free/lab setup.

@montenegro i should point out that i do see interfaces in the dataplane and seem to 'operate' in that they are able to see a neighbor.

Derelict

@montenegro Did you perform those steps and get the uio_hv_generic module loaded?

montenegro

@derelict i did -- but the system is throwing errors about the interfaces that i had loaded previously. i will do a clean install and try these steps before trying to add any interfaces into the dataplane

montenegro

@derelict this worked -- thanks so much !
