Hello,

I'm trying to instantiate an experiment (name is mlos-2) on the Wisconsin cluster, and I receive the following message:

Experiment setup on the Cloudlab Wisconsin cluster failed: SliverStart: Failed to set up experimental networks

My profile is mlos-nautilus-ddss, which is pretty similar to small-lan. I briefly looked into the logs, and there are multiple instances of the following:

ERROR - unable to clear vlan 1103 for [spinesw-z9100-110242:0.32] on trunk on switch spinesw-z9100-110242 spinesw-z9100-110242::createExpectObject(): Could not connect to switch: Password incorrect! WARNING: Unable to connect to spinesw-z9100-110242

spinesw-z9100-110242::setChannelVlan: Error removing vlan 1103 from channel Po8: Unable to connect to switch spinesw-z9100-110242.

Could you please take a look at it?

Thanks,

Konstantinos

Note: the error occurs only when setting >1 nodes in the experiment.

Sorry, a configuration setting went missing after the OS upgrade.
This should be fixed now.
