LattisNet(R) System 3000(tm)
Model 3910S FDDI Network Management Module
Highlights
* Provides management capabilities for LattisNet System
3000 FDDI networks operating at 100 Mb/s
* Advanced three MAC/three path architecture provides configurati flexibility
* Fully compatible with ISO and ANSI FDDI standards
* On-board SNMP agent enables integration with Optivity(tm) network
management system
* Supports SMT-to-SNMP proxy for gathering management information from
* On-board 29000 RISC procesor distributes management processing
power to the hub
* Out-of-band management interface enablesnetwork management to
continue over serial point- to-point lines shouldin-band
communications fail
The LattisNet(R) Model 3910S Fiber Distributed ta Interface (FDDI)
Network Management Module works with the UNIX-based Optivity(tm) network
management system (formerly LattisNet Manager for UNIX) to provide
comprehensive, distributed management of 100 megabit per second (Mb/s)
LattisNet FDDI netws.
The Model 3910S occupies two slots in a LattisNet System 3000
concentrator, where it attaches to network management and FDDI buses on the
concentrator's backplane. In FDDI networks, each host station supports the
American National Standards Institute's (ANSI) FDDI Station Management (SMT)
protocol. The Model 3910S collects SMT-generated data from the host
stations, and an on-board AMD 29005 RISC processor processes the management
frames within the concentrator. A resident SMT-to-Simple Network Management
Protocol (SNMP) proxy agent enables the central management station - a Sun
SPARCstation running Optivity - to access local and remote SMT data.
By supporting industry-standard SNMP, the Model 3910S is capable of
passing management data through bridges or routers in extended networks.
SNMP compatibility also enables network administrators to manage LattisNet
Ethernet, Token Ring and FDDI networks, as well as other SNMP-compliant
devices, from a single management station.
Three Communication Paths
Three Media Access Control (MAC) entities on the
module enable the Model 3910S to manage three paths within the concentrator:
primary, secondary and local. FDDI stations are assigned to an internal path
from the management station.
The Model 3910S is fully compatible with the International Standards
Organization's FDDI Media Access Control (MAC), Physical Medium Dependent
(PMD) and Physical Protocol (PHY) standards. The module also supports the
most current version of the ANSI FDDI X3T9.5 SMT protocol (Version 6.2). In
the future, as the standard evolves, software upgrades will ensure continued
compatibility until the standard is finalized.
The Model 3910S supports 2 megabytes (Mb) of ROM on-board,
incorporating full FDDI management information base (MIB), SMT, Simple
Network Management Protocol (SNMP) and diagnostic software at the board level.
An additional 2 Mb of RAM enables SMT and SNMP to be downloaded from the
management station using TFTP. A local load option is also available to
allow startup without intervention by the network management station.
Module Interfaces
The Model 3910S offers fiber optic Media Interface Connectors (MICs)
as the interface to the network. Two MIC ports are offered on the module face
plate, labeled as Port A and Port B, to enable peer, tree, null-attached and
dual-homed network configurations.
In addition, the Model 3910S offers three other interfaces to
support various management functions. A service port, featuring a DB-9 male
connector, enables diagnostic and configuration data to be obtained at the
management station. An RS-232 serial communications port, implemented with
a DB-25 male connector, enables the module to communicate with the management
station out-of-band, via a modem link, should in-band communications fail.
The module also includes an optical bypass switch (optional) for
nodes attached to dual rings. The switch function, implemented through a
6-pin mini-DIN connector, enables the network manager to remove the
concentrator from the ring without causing the network to wrap.
LED Indicators
The Model 3910S features an array of front panel LEDs to
indicate module status, faults, wrap conditions and active paths at a glance.
In addition, individual port LEDs indicate activity, link error alarms, fault
and configuration status (tree or peer) for the A and B MIC ports.
