get-con-matrix
Displays the current connectivity matrix for the switch. The first
column is the source port. The other columns are destinations where
frames from a given source port can be forwarded. Unlearned
addresses (addresses that aren't in the switching database) are
forwarded to all ports marked with a + in the source port's row.
Learned addresses are forwarded to their destinations only if the
destination is marked with a + in the source port's row. Ports don't
need to be forwarded to themselves.
