Statements of Compliance
FCC
This device complies with Part 15 of the FCC rules. Operation is subject to the following two
conditions: (1)this devicemay not cause harmful interference, and (2) this device must accept
any interference received, including interference that may causeundesired operation.
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to providereasonable
protection against harmful interference when theequipment is operated in a commercial envi-
ronment. This equipment uses, generates, and can radiate radio frequency energy and if not
installed in accordance withthe operator’s manual, may cause harmful interference to radio
communications. Operation ofthis equipment in a residential area is likely to cause inter-
ference in which case the user will be required to correct the interference at his own expense.
Changes or modifications made to this device which are not expressly
approvedby Cabletron Systems couldvoid the user’s authority to operate the
equipment.

This manual supplements screen prompts and menus as an aid in configuring thedatabase and
performing system operations on a Netlink FRX8000. Beforeusing themanual,you should be
familiarwith FRX8000 hardware,as well asthe protocols (frame relay,SNA, etc.) you will be
using.
Terminology andConventions
This typeface represents general text. This typeface representskeyboard input and video output.
(This textis darkcyan in on-screen versions of the manual,and black in paper versions.)
In on-screen versions of the manual, items in blue arelinks to other places in the manual.
This symbolpoints to an informational noterelatingto thetext, table,or figurethat
immediately precedes or follows it.
This symboland text identifies a cautionary note, the content of which ismore
critical to heed than an informational note.
The following references to keyboard keys appear in the manual and/or on the screen:
[N] is a reference to a key on your keyboard (where “N” is the key).
Enter means that you should type in the information, then press the[Enter] key.
Type is similar to Enter, except that the word “[Enter]” follows the information to be
typed (e.g., “type n [Enter]”).
Press means press (hit, strike) the key once. Pressing the [Enter] key afterwards is not
necessary.
[Ctrl] followed by one or two other key designations, must be strucksimultaneously
with the other keys shown.
Ifa statementends withareference toa key—forexample,“....thenpress [Enter].”—the period
is not part of the data to be entered. If a period should be entered, it will be shown as [.]. The
sameapplies to all other punctuation. When instructed to, for example, “press [A], [B] fromthe
Main Menu,” this means press [A], then [B], not [A] comma [B].
ScreenDisplays
Screen Displays are provided to show the general appearanceof actual screens. They areonly
examples—the information shown is not always representative of an operational system.

Overview
The NetlinkTM FRX8000 is a fully integrated LAN/WAN enterprise switch, con-
necting remote network sites with a robust switching technology that allows trans-
missionof LAN and WANdata trafficover a singleaccessline. The FRX8000 allows
the features of conventional multi-protocol routers to be combined with those of fast
packet switches,delivering high performance regardlessof the demandsof the access
protocols being used.
Some typical applications of the FRX8000:
●SDLC-to-LLC2 and LLC2-to-QLLC conversion over frame relay
●SNA and TCP/IP LAN/WAN integration—with or without routers.
●Banking applications—LAN, SNA, TCP/IP, async.
●Feeder networks to public frame relay services.
●“Front end” network to larger frame relay switches.
●Public and privateaccess and backbone applications.

Versatile Management Functions
Connection Management
●Connection prioritizing and dynamic bandwidth assignment
●Multiple transport classes, configurable per connection
●Protocol-independent SPF (shortest path first) routing among FRX8000s
●Dynamic load balancing
Network Manager
●Two types:
◆FRX8000 INM (Integrated Network Manager) is an FRX8000 Switch and
network manager in the same box.
◆NMP is a stand-alonemanager, connected to thenetwork viaan attached
Nucleus 7000 (N7400/N7500) node.
Nucleus7000 Release 5.0 is supported in the current release of
FRX8000, to allow a smooth transition of existing N7000 net-
works to FRX8000.
●Intuitive, menu-based system that provides complete local management (via
local VGA monitor or remote ASCII terminal) of network nodes
●Filetransfer between INMs/NMPs, and from an INM or NMPto an ICP. (ICP
is an FRX8000 Switch with all the functionality of the INM except the user
interface)
●Remote software updates to FRX8000 Switches
●Self-learning route configuration
●Centralized alarm routing
●Statistics displays
SNMP Management Support
●Support of get, get_next, and (for some fields) set commands from SNMP
manager, providing topology information and node status
●FTP and telnet access to ICPs, INMs, and NMPs
●MIB II (RFC 1213) System & Interfaces Group, plus parts of frame relay
(RFC1315) and SDLC (RFC1747) MIBs
●Enterprise network status information via local MIB on node
