Introduction

Chapter 1

The 9T425-16, 9T427-16, and 9T428-16 Token Ring SmartSwitch 9000 are Enterprise Backbone switches supporting Smart Networking Services, RMON per port and Dedicated Token Ring. The 9T425-16, 9T427-16, and 9T428-16 modules (shown in Figure 1-1) provide sixteen ports, either UTP or STP for the 9T425-16 and 9T427-16, or multimode Þber for the 9T428-16. Combined with its connection to the INB2 backplane, this provides for up to 112 or 224 separate Token Ring segments to be interconnected within a single SmartSwitch 9000 chassis.

Features

Processor

The 9T425-16, 9T427-16, and 9T428-16 are equipped with an advanced Intel i960 microprocessor. This microprocessor provides a platform for all management functions within a scalable RISC-based architecture.

SmartSwitch 9000 ASIC – Distributed Switching

These modules provide the fastest Switching fabric available at 750 Kpps. Each module contains its own switch fabric - eliminating central board Single Point of Failure.

Modules

System Management

As with most SmartSwitch 9000 modules, the 9T425-16, 9T427-16, and 9T428-16 interface to the two System Management Buses (SMB-1 and SMB-10) for intermodule management.

Connectivity

The 9T425-16, 9T427-16, and 9T428-16 provide sixteen front panel C-ports, allowing direct station attachment or station emulation for hub connections. STP and UTP cables are supported by the 9T425-16 and 9T427-16, and multimode Þber is supported by the 9T428-16.

Introduction

Packet Switching

Packet Switching occurs between the front panel Token Ring connections and/or to any other module in the chassis via the INB2 bus. These modules are capable of Transparent Bridging or Source Route Translational Bridging. IEEE 802.1d Spanning Tree Protocol is supported in all bridging functions.

Source Route Translational Switching

Allows both transparent (TP) and Source Route (SR) packets to be forwarded. SR packets are translated to TP; the Route Information Field (RIF) is stripped and cached on each front panel port inbound SR. Outbound packets are automatically reverse-translated by appending RIF data from the RIF cache into the packets before transmission.

Management Information Base (MIB) Support

The 9T425-16, 9T427-16, and 9T428-16 modules provide MIB support including:

¥ IETF MIB II (RFC 1213) ¥ IETF RMON MIB (RFC 1757 and 1513) ¥ IETF Bridge MIBs (RFC 1493 and 1525) ¥ IEEE 802.5 Token Ring MIB (RFC 1748) ¥ IEEE DTR MAC MIB ¥ Cabletron Enterprise MIBs

For a complete list of supported MIBs, refer to the release notes provided in

NOTE

LANVIEW LEDs

the module package.

The 9T425-16, 9T427-16, and 9T428-16 use LANVIEW Ð the Cabletron Systems built-in visual diagnostic and status monitoring system. With LANVIEW LEDs, you can quickly identify the device, port, and physical layer status at a glance.

Hot Swapping

The 9T425-16, 9T427-16, and 9T428-16 can be installed or removed from the chassis while the SmartSwitch 9000 is powered up without affecting the operation of the remaining modules in the chassis.

RMON

Five RMON groups are supported in the 9T425-16, 9T427-16, and 9T428-16: Statistics, History, Alarms, Events, and Token Ring.

Broadcast Thresholds

The 9T425-16, 9T427-16, and 9T428-16 contain broadcasts in the event of a broadcast storm.

Introduction

SFVLAN (SecureFast Virtual LANS)

The 9T425-16, 9T427-16, and 9T428-16 allow connection-orientated Switched Virtual Circuits (SVC).

Protocol T ranslations

The 9T425-16, 9T427-16, and 9T428-16 allow Òany-to-anyÓ connectivity for IPX, IP, SNA, Netbios, Appletalk protocols between Token Ring and Ethernet, FDDI, and Fast Ethernet devices.

Dedicated Token Ring - Auto TXI or TKP Modes

The 9T425-16, 9T427-16, and 9T428-16 can operate in either TXI (Transmit Immediate, a.k.a. Full Duplex) or TKP (Token Passing, a.k.a. Standard) modes. TXI is tried Þrst. If this is incompatible with other products on the ring, TKP mode is used.

Auto MTU Size

If the user changes the ring speed, The MTU is automatically set to the maximum size for that speed. The maximum allowable MTU is 8130 bytes @16 Mbps or 4500 bytes @4 Mbps. The user may set the MTU to a smaller size, if desired.

Auto Ring Number Detection

The 9T425-16, 9T427-16, and 9T428-16 set the Ring Number automatically to match the current number in use on the ring segment. (May be toggled off. The default setting is enabled.)
