Alcatel's Omni Switch/Router (OmniS/R) is an advanced, multi-layer switching platform (Layer 
2 and 3) that supports the most demanding switch requirements. With Omni Switch/Router, 
network administrators can replace aging 

 

FDDI 

 

or Fast Ethernet backbones with high capacity 

Gigabit Ethernet backbones. 

 

♦

 

♦

 

Beginning with Release 4.4, 

 

FDDI

 

 is no longer 

supported. Beginning with Release 4.5, ATM, Token 
Ring, M013, and Mammoth-based Ethernet Modules are 
no longer supported.

Omni Switch/Router modules can be distinguished 
from older OmniSwitch modules by the 

 

 in the 

module name. For example, the 

 

ESM-100C-32W

 

 is an 

OmniSwitch module whereas the 

 

ES

 

-100C-32W

 

 is an 

Omni Switch/Router module.

Omni Switch/Router has a distributed switching fabric. In a 9-slot chassis operating at full 
duplex, Omni Switch/Router offers an aggregate 22 Gigabit per second (Gbps) distributed 
switching fabric. In addition, Omni Switch/Router offers new high density switching modules, 
including auto-sensing 10/100 Ethernet modules that offer high speed network connections to 
servers and desktops. (See 

 

for examples.)

The 

 

Omni Switch/Router

 

 Management Processor Module (

 

MPX

 

) module provides the core 

routing, 

 

VLAN MAC

 

 learning, 

 

SNMP

 

, and file management functions for the entire Omni 

Switch/Router. In addition, the 

 

MPX

 

 has an Ethernet plug-in port for managing the switch. 

Only one 

 

MPX

 

 is required per Omni Switch/Router, but you can add another 

 

MPX

 

 for 

redundancy. See Chapter 2, “The Omni Switch/Router 

 

MPX

 

,” for more information on 

the 

 

MPX

 

.

Omni Switch/Router switching modules require an 

MPX

. You cannot install any version of the 

MPM

 (i.e., 

MPM-C

, 

MPM 1G

, 

MPM II

, or original 

MPM

) in a chassis 

with an 

MPX

.

An Omni Switch/Router Hardware Routing Engine (

HRE-X

). The 

HRE-X

 offers high-speed 

Layer 3 switching from 1.5 to 12.0 million packets per second (Mpps) in a fully loaded 
chassis. See The Omni Switch/Router Hardware Routing Engine (HRE-X) on page 1-22 for 
more information on the 

HRE-X

.

Omni Switch/Router switching modules perform software filtering, translations between 
dissimilar network interfaces, and hardware-based switching. Omni Switch/Router switching 
modules have an additional on-board interface connector for the 

HRE-X

.
