The cEOS-lab and vEOS-lab platforms use a different “forwarding plane” than EOS and CloudEOS; it is a software forwarding agent called Etba. A more efficient Etba provides more flexibility and better scalability for virtual network simulation for cEOS-lab and vEOS-lab users.

This feature adds an “exec” command for tracing that incorporates a time limit. Such time limited traces can be executed like so: start trace AGENT setting TRACE timeout TIME ( seconds | minutes | hours ). This is in contrast to the “config” commands for tracing, which do not have a time limit.
