Welcome to NetSight Element Manager STS16-20 UserÕs Guide . We have
designed this guide to serve as a reference for using NetSight Element Manager to
monitor and manage the family of SmartSTACK Token Ring STS16-20 switches.
The STS16-20 is a high performance, intelligent 20-port Token Ring switch that
provides switching intelligence to network backbones, workgroups, and desktop
connections.
The STS16-20 complies to IEEE 802.5 and supports 802.1D bridging. The STS16-20
provides half or full duplex connections, auto-conÞguration, enhanced bridging
capabilities, port-based VLANs, and four groups of RMON.
The STS16-20 devices include the STS16-20D, STS16-20R, STS16-20RM, and
STS16-20FRM. These devices are functionally identical, except for the
conÞguration of ports.
¥ The STS16-20D has 20 built-in RJ-45 ports Ñ16 workstation ports and 4
network ports.
¥ The STS16-20R has 20 built-in RJ-45 ports; a RI/RO-like connection is available
on all ports.
¥ The STS16-20RM has 20 built-in RJ-45 ports and supports two slots for
optional SmartSTACK Interface Modules (SSIMs). A RI/RO-like connection is
available on ports 19 and 20 and when a Þber expansion module is installed.
¥ The STS16-20FRM has 20 built-in Þber VF-45 ports and supports two slots for
optional SmartSTACK Interface Modules (SSIMs). A RI/RO-like connection is
available on all ports.
NOTE
For the STS16-20D, ports 1 through 16 are workstation ports, which support a single
MAC address per port; ports 17 through 20 are network ports, which provide full network
connectivity without a limitation on the number of MAC addresses that can be learned
per port. Refer to your hardware documentation for more information.
