\item
Linux inside the WR Switch enumerates WR interfaces starting from 0.
This means we have to use internally port indexes 0..17. However, the

generated from the switch use the Linux port numbering. The consequence is
that every time Syslog says there is a problem on port X, this refers to
port index X+1 on the front panel of the switch.
