BreezeACCESS Version 4.5 System Manual
Degradation Limit. Higher demand can be expected in cases of
significant over subscription and/or in deployments where a
high number of subscribers are in locations that do not enable
proper communication with the AU at the highest data rate.
Valid values: 0 – 70 (%).
Default value: 70 (%).
"
Mir Only option (AU only) – Enables or disables the option of
forcing the MIR/CIR algorithm to use MIR values only. The
MIR/CIR algorithm determines the actual information rate for
each of the supported SUs under changing demand conditions,
based on the configured CIR and MIR values. When the Mir Only
Option is enabled, the MIR/CIR algorithm is overridden and is
forced to operate with MIR values only (e.g. the AU attempts to
enable all SUs to transmit/receive information at the specified
MIR value.
When enabled, the graceful degradation algorithm,
which is a part of the CIR/MIR algorithm, is also disabled.
The default is Disable .
"
Show MIR/CIR Parameters – Displays the current values of the
MIR and CIR parameters. In SUs, the display includes the
Run-Time MIR/CIR Option, which is the actual status of the
option (may be different from the MIR/CIR Option selected in the
SU because it is controlled by the AU).
!
Show Service Parameters – Displays the current values of the
Service Parameters .
RADIUS Parameters Menu
(Subscriber Units only)
Managing a large number of users creates the need for significant
administrative support together with careful attention to security,
authorization and accounting. The use of RADIUS (Remote
Authentication Dial In User Service) enables operators to manage a
single "database" of users, supporting authentication (verifying user
name and password) as well as configuration information detailing the
type of service to deliver to the user and the traffic that the user
transmitted and received, for billing proposes.
The RADIUS is a protocol for carrying authentication, authorization,
and configuration information between a Network Access Server, which
desires to authenticate its links and a shared Authentication server. A
Network Access Server (NAS) operates as a client of RADIUS. The client
is responsible for passing user information to designated RADIUS
servers, and then acting on the response. RADIUS servers are
responsible for receiving user connection requests, authenticating the
user, and then returning all configuration information necessary for the
client to deliver service to the user.
