7210 SAS M, X Basic System Configuration Guide Page 11
Preface
About This Guide
This guide describes system concepts and provides configuration explanations and examples 
to configure 7210 SAS M boot option file (BOF), file system and system management 
functions.
All the variants of 7210 SAS-M can be configured in two modes, that is in network mode and 
in access-uplink mode. In network mode configuration 7210 SAS-M uses IP/MPLS to provide 
service transport. In access-uplink mode configuration 7210 SAS-M uses Ethernet QinQ 
technology to provide service transport. The mode can be selected by configuring the BOF 
appropriately.
NOTE: In either mode, it is expected that the user will only configure the required CLI 
parameters appropriate for the mode he intends to use. Unless otherwise noted, most of the 
configuration is similar in both the Network mode and access uplink mode. 
Note :Only 7210 SAS-M supports access-uplink mode. 7210 SAS-X does not support access-
uplink mode.
This document is organized into functional chapters and provides concepts and descriptions of 
the implementation flow, as well as Command Line Interface (CLI) syntax and command 
usage.
