| 6.3.4 | Frame R elay switching tables

The Frame Relay switching table consists of four entries: two for incoming port and DLCI, and two for outgoing port and DLCI, as shown in the Figure. The DLCI could, therefore, be remapped as it passes through each switch; the fact that the port reference can be changed is why the DLCI does not change even though the port reference might change.
