Using Translation Bridge Services
114060 Rev. A 4-7
LAN Speeds
When the translation bridge transfers frames between networks that have different
network speeds, the software automatically accommodates for variations in
throughput. If the difference in speeds is significant, the translation bridge may
drop some frames.
Implementation Notes
The following sections contain specific information you should know before you
use the Bay Networks translation bridge.
Protocols Supported
The translation bridge supports the transfer of logical link control-based (LLC)
traffic. You can designate the service access points (SAPs) that the translation
bridge accepts. By default, the translation bridge accepts traffic destined for
NetBIOS (0xF0), Systems Network Architecture (SNA) (0x04, 0x08, 0xFC), and
LAN Network Manager (LNM) SAPs (0xF4).
Interfaces Supported
The translation bridge can operate on all TB interfaces supported by the Bay
Networks router, including
• Ethernet/802.3
• Fiber Distributed Data Interface (FDDI)
• Bay Networks serial
• Frame Relay
• Switched Multi-Megabit Data Service (SMDS)
• Point-to-Point Protocol (PPP)
• Token Ring encapsulation
The translation bridge can operate on all SR interfaces supported by the Bay
Networks router except IP, but including
• Token Ring
• Bay Networks serial
