DLSw Slot Table
Each slot on a Bay Networks router running DLSw acts as an independent data
link switch. Each slot is identified by assigning a unique IP address for the slot.
This mapping is done in the DLSw Slot Table. Each entry in the table consists of a
DLSw slot number plus the address of the IP interface you allocate for that slot.
The router uses this IP address to establish the TCP sessions between peers in a
DLSw network. Generally, the IP address that you select is either the circuitless IP
address or the IP address of any interface on this slot. However, it is acceptable to
use the IP address of any interface on any slot.
