Stinger configuration overview
Before you configure a Stinger unit, create a diagram that illustrates how the unit
will interoperate with your current network configuration. Creating a comprehensive
network diagram helps prevent problems during installation and configuration, and
can help in troubleshooting any problems later.
Stinger configuration tasks include the following:
■
Configuring the primary or single control module
■
Configuring the DSL line interface modules (LIMs)
■
Configuring the trunk modules
■
Defining ATM traffic contracts
■
Configuring connections, either locally or through RADIUS
Primary (or single) control module configuration
Most sites operate the unit with redundant controllers, although it can operate with a
single controller. If the unit has two control modules installed, check the status lights
on the control module front panel to see which control module is the primary
module. For details, see Table 3-2 on page 3-6.
Each control module has an RS-232 serial port (labeled DIAG PORT) and a
10/100BaseT Ethernet port. The serial port is for system management from a local
workstation. It is also the standard port for error output, stack traces, and messages in
the event of a system crash. Until you have configured IP addresses on the system’s
Ethernet interfaces, you must use a local terminal or workstation connected to the
serial port of the primary control module to configure the Stinger unit. There is no
other way to log into the unit to perform the initial configuration.
The system’s Ethernet ports are intended for light data and management traffic. Once
you have assigned IP addresses, you can Telnet into the unit from a local host and
download configuration files from a TFTP server to the Stinger system.
A Stinger unit has a range of options for configuring IP and for protecting the unit
from unauthorized administrative access. In addition, if you are using redundant
control modules, verify that the default control module redundancy configuration is
appropriate for your site.
Note
All configuration must take place on the primary control module. The
configuration repository of the primary control module overwrites that of the
secondary control module immediately after every configuration change and at
regular intervals.
Line interface module (LIM) configuration
A Stinger unit supports any combination of ADSL, HDSL2, SHDSL, IDSL, or SDSL
ATM modules. However, only the first 48 ports on 72-port LIMs are supported on the
original Stinger FS chassis. Each port on a LIM has a variety of configuration options,
including line rates and bandwidth. The way you configure each line depends on
your connectivity needs.
