SSIM-H2-02 Fast Ethernet - Translational Switch SmartStack Interface Module Installation and User Guide
Feature Description
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.
The SmartStack SSIM-H2-02 can serve as
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.
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.
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.
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
