IP and LAN Protocol Support
Physical LAN Connectivity
Introduction The Vanguard products offer serial interfaces for connection to Ethernet and Token
Ring LAN.
Ethernet 802.3 Vanguard Ethernet functionality complies with the IEEE 802.3 specifications and
provides Transparent Bridging to transport many different protocols over the Wide
Area Network (WAN) to remote destinations. Supported protocols include:
• Novell Netware
•DECnet
• Banyan Vines
Token Ring 802.5 Vanguard Token Ring LAN functionality complies with the IEEE 802.5
specifications and provides Source Route Bridging to transport many different
protocols over the Wide Area Network (WAN) to a remote destination. Some of the
supported protocols include:
• Novell NetWare
• SDLC Cluster Controller
• IBM PC LAN
• NetBIOS
• IBM 3270 Emulation 3.0
• IBM APPC
See the IEEE 802.5 specification for additional details on Token Ring functionality.

LAN Forwarding Options
Introduction The Vanguard products supports three forwarding options for carry traffic and
interconnecting LANs. The Vanguard can act as a:
•Bridge
•Router
• Bridge Router (BRouter)
Bridging Bridges work at the Data Link layer providing connectionless service. Vanguard
products support bridging of data traffic for Token Ring and Ethernet LANs.
Bridging LAN traffic minimizes your networking costs by eliminating the need for
redundant networks and maximizes the availability of dedicated facilities such as
servers and printers, as well as public Frame Relay and X.25 services, across
multiple LANs. The Vanguard supports these types of bridging
• Translational Bridging
• Source Route Bridging for Token Ring
• Transparent Bridging
Routing Router interconnect network segments and transport data across an network from a
source to a destination. Routers store and forward data in an network regardless of
network topology. Routers operate at the Network layer and, therefore, offer some
flexibility in choosing several network level services.
Bridge Routing When configured as a bridging router, the Vanguard supports both bridging and
routing within the same node concurrently. The Vanguard provide bridging router
functions including
• Routing packets if a specific routing protocol is globally enabled.
• Filtering packets if you configure specific protocol filters.
• Bridging packets if they are not routed or filtered. In this case, they are
forwarded according to their destination MAC address.
