Monitoring
Monitoring is a function that reads the cell counter of the hardware. It checks the
total number of cells exchanged in the ATM Switch, the number of error cells, and
the number of discarded cells, etc.
When an overflow occurs (at 4 cells), the cell counter stops counting
cells.
The information on the ATM Switch traffic and performance can be checked for
each line, connection, or line physical level by inputting the command
DISPLAY traffic
from a MAT. For details on the
DISPLAY traffic
command, refer to the appropriate Command Manual.
Hardware Management
The hardware management unit controls the following:
■
Static hardware configuration
■
Dynamic hardware configuration (operation status management)
■
Hardware revision
■
Software revision
■
Own IP address
■
NMS address
■
Connection-related parameter control (e.g., the number of VPIs of the line)
These pieces of information are stored in a database called a Management
Information Base (MIB). Information stored in the MIB can be set and read from
a MAT.
The NMS uses Simple Network Management Protocol (SNMP) to access the MIB
of each device in the network and centrally manage faults and configuration data
of the devices.
