Notes:
1. New mode names can be defined on the router using the Command Line
interface. These new mode names can be mapped to existing Class of Service
(COS) definition names or to new COS definitions, which may be defined using
the Configuration tool.
2. Limited resource link stations are supported for:
vconnection network links
