Hi Steven, thank you for letting us know about your use case,
The problem is caused because since 6.1 release we run
part of network verification tasks before deployment , from
the code it can be seen, that this check is hardcoded , before
we send any deployment tasks, so we should figure out a way
to fix it.
1. run network verification us a part of deployment, somewhere
in pre_deployment stage, between pre_deployment/4999 and
pre_deployment/6000 , but it doesn't cover the case when user
wants to just run network verification on Network tab
2. introduce new stage pre_network_verification which will be
run before we start network verification, so you will be able
to configure switches
Also I would like to notice, that role as a plugin feature which
will allow to change deployment graph of the core, will not help
here . Because network verification is not a part of the graph.
