The translation bridge service

• Supports communication between systems on SRB and Ethernet/802.3

segments locally attached to the same router

• Maps between SRB and Ethernet/802.3 framing requirements

Memory Requirements

DLSw provides buffering of LLC2 packets in single switch mode, and additional

buffering of TCP packets in dual switch mode. Therefore, DLSw can use a

signiﬁcant amount of memory.

To limit the memory consumption, Bay Networks provides several mechanisms,

including

• LLC2 Max Links parameter, allowing the network administrator to limit the

number of LLC2 stations per interface. Refer to Conﬁguring LLC Services.

• DLSw Max Slot Sessions parameter, allowing the network administrator to

limit the number of LLC2 stations per slot. See Chapter 5 for instructions on

accessing and editing the Max Slot Sessions (DLSw global) parameter.

• Technician Interface commands, allowing the user to limit the total memory

used by DLSw.
