Feature

Description

 

 

 

 

SNMP

SNMP is supported via the host processor (the

 

processor on the SmartStack STS16-20RM).

 

This makes it possible to configure the device

 

in a standards-based way and as an integrated

 

part of the LAN switch.

 

 

Can serve multiple

The SmartStack SSIM-H2-02 can serve as

switches in one stack

uplink for multiple LAN switches

 

interconnected by a stacker. This reduces the

 

cost of connecting a number of LAN switches

 

to an Fast Ethernet backbone.

 

 

Dual home FEP

A Token-Ring network using SRB can support

 

duplicate MAC addresses. This capability has

 

been exploited by SNA gateways, which can

 

provide a redundant host connection: two

 

gateways have the same MAC address but are

 

on different rings and due to the source routing

 

discovery process the SNA sessions are

 

randomly distributed between the two

 

gateways. Sessions are established between

 

configured MAC addresses.

 

 

Protocol filters

The SmartStack SSIM-H2-02 offers the same

 

protocol filters as the SmartStack STS16-

 

20RM. This makes for consistent protocol

 

filtering and thereby reduces the risk of

 

network congestion and security breaches.

 

 

Broadcast Suppression

On output, the Translational Switch SSIM

 

must keep the rate of broadcast frames sent to

 

Ethernet within the limit set by the Maximum

 

Broadcast Frame Count per Second

 

configuration parameter. Broadcasts include:

 

- ARE, STE source routed frames

 

- unknown destination frames

 

- frames with the MAC header broadcast bit set
