EVICES
Remote devices that may connect to the CyberSWITCH include the following:
•
•
MAC Layer Bridges
•
IP Host Devices
•
IP Router Devices
•
IPX Routers
•
AppleTalk Routers
MAC layer bridges connect to the system using the HDLC bridge encapsulation line protocol.
These devices send transparently bridged Ethernet frames to the system. MAC layer bridges do not
process network layer protocols. They forward all packets based on source and destination MAC
addresses.

IP Host devices are single workstations or PCs that connect to the system at the IP network layer.
These devices use either the RFC1294 based protocol or PPP to communicate with the system.
These devices use either the RFC1294 based protocol or PPP to communicate with the system.
IP router devices are single devices that represent many other IP hosts and routers to the system.
They must use the CHAP or PAP protocol to identify themselves to the system. IP routers usually
provide IP network address information at connection time (and use PPP to send user data to the
system).

IPX routers are single devices that perform network layer tasks (addressing, routing, and
switching) to move packets from one location on the network to another. IPX routers use the
Internetwork Packet Exchange (IPX) protocol, typical of the NetWare environment.

AppleTalk routers route AppleTalk datagrams based on address information. They support the
following protocols: RTMP, NBP, and ZIP.
