Well, there should be a process called salRefApp. Can you please stop
the freerouter systemd service and then execute directly the command
that's bound to the bfswd alias?

core#
core#show logging process bfswd
Using bf_router profile "NOP_MCHOME"

That's only the output of the wrapper script that starts the actual
SAL. There must be more output. Maybe right after you restart the
process? Otherwise you can start it by hand just to see what happens.

Hi

On the 2556 the bfswd process is actually the SAL which waits for a
connection from bffwd. The actual bf_switchd is only started after
bffwd has connected sucessfully and asked the SAL to start bf_switchd
so this can't have happened yet if the connection fails. Can you show
me the output of the bfswd process please?

Also, which version are you using (tna-list-long-installed)?
