Traffic Management

You can use the CoreBuilder 9000 ATM Enterprise Switch Local
Management Application (LMA) or Transcend
other SNMP-based network management application) to manage your
CoreBuilder 9000 ATM Enterprise Switch.
The CoreBuilder 9000 ATM Enterprise Switch LMA is a
character-oriented, menu-driven user interface for performing
system-level administration. You operate this console from a terminal (or
terminal emulation software) or through a remote terminal protocol, such
as Telnet or Remote Login.
For more complete network management, use an external SNMP-based
application such as Transcend Enterprise Manager. Transcend provides
logical views and control for your network. In addition, it extends the
SNMP capabilities of the ATM Enterprise Switch with a common user
interface and easy-to-use administrative features that optimize network
configuration, oversight, and troubleshooting. For more information
about Device Management, see Chapter 17.
Traffic management in the CoreBuilder 9000 ATM Enterprise Switch is
done at two levels:
