Stinger MRT ATM switching overview
A Stinger MRT unit receives cells on a link that is identified by a pair of unique
attributes. These attributes are known as the virtual path identifier (VPI) and the
virtual channel identifier (VCI). The Stinger MRT switches cells from an incoming
link to an outgoing link, based on the VPI and VCI attributes of each link. The
connection between these links is a static configuration entered by an administrator.
This guide covers only basic installation information and configuration of the Stinger
MRT unit. More detailed information about configuring the unit to support ATM
traffic can be found in the Stinger ATM Configuration Guide.
Stinger MRT configuration overview
Before you configure a Stinger MRT unit, create a diagram that illustrates how the
unit will interoperate with your current network configuration. Creating a
comprehensive network diagram helps prevent problems during installation and
configuration, and can help in troubleshooting any problems later.
Stinger MRT configuration tasks include the following:
