Introduction

The Token Ring Administrator's Guide describes the Silicon Graphics® device drivers for the 802.5 Token Ring communications protocol. The guide includes basic Token Ring concepts as well as configuration issues for the IRIS® Token Ring product. The IRIS Token Ring product provides network access for Silicon Graphics applications, including TCP/IP-based network applications, IBM® emulation and connectivity products, and NetVisualyzer™.

IRIS Token Ring can be a station's only network connection, or it can be one of many network connections operating simultaneously (for example, with Ethernet and/or FDDI).
