Upstream Traffic Shaping In A Hosted System; Hosted Mrt System Management; Upgrading Hosted Mrt System Software; Figure B-5 Port-Level Cac Sequence (Performed Only At Provisioning Time - Lucent Technologies Stinger MRT 19 Getting Started Manual

When port-level CAC is enabled, the system performs two additional CAC
calculations before allowing a connection to be provisioned. The port-level CAC
sequence is shown in Figure B-5. If sufficient bandwidth is not available at any
one of the calculation points, the connection profile cannot be written.

Upstream traffic shaping in a hosted system

The system shapes traffic in the transmit output direction at the maximum line
rate of a host trunk port and of every slave cascade port in the system. The line
rate is not configurable for these interfaces. Virtual path shaping, which enables
traffic shaping control on a per-VPI basis, can be configured and applied only at
the host trunk ports.
For LIM interfaces on the host and on remote shelves, the
allow-max-up-stream-bandwidth setting provides a configurable maximum line
rate for upstream traffic from the LIM.

Hosted MRT system management

This section describes some common administrative tasks and the procedures,
commands, and profiles specifically related to hosted systems. For general system
management procedures, see the Stinger Administration Guide. For details about
specific commands and profiles, see the Stinger Reference Guide.

Upgrading hosted MRT system software

To upgrade a hosted Stinger MRT system, you must first upgrade the host's
software by following the upgrade instructions for the new software version. This
section explains related issues.
If you are upgrading a Stinger MRT system from an earlier software version, the
system preserves the existing configuration and operation of a standalone MRT
or a set of subtended units. However, to convert the system to hosted operation,
you would need to modify the subtending configuration.
