OAM Traffic Throttling
The SPI-2213 provides a function that suppresses OAM related traffic which can occur in
the system depending on the operator command. The OAM related traffic includes fault
trap messages for alarm reports and statistics files that are created periodically.
In a fault trap, the operator can use an alarm inhibition command to suppress alarm
generation for all or some of system fault traps. This helps control alarm traffic.
In a statistics file, the operator can use commands for statistics collection configuration to
control the size of statistics file by disabling collection functions of each statistics group.
Throughput Test
The SPI-2213 provides a throughput test for the backhaul to the ACR. The SPI-2213
supports a server and client function for throughput tests.
The operator can set up target IP addresses, test duration, and bandwidths for throughput
tests, and check throughput and loss as test results. However, as the throughput test affects
system performance and call services, it is recommended not to perform the test during in-
service.
System Log Control
The SPI-2213 provides a log and log control function per application.
An application log can be created by an operator command or its debug level can be set.
The operator can usually keep the log function disabled, and when the log function is
necessary, he can change the debug level (Very Calm, Calm, Normal, Detail, Very Detail)
to enable logging and log save functions.
However, enabling log functions for many applications while the SPI-2213 is running may
affect the system performance.
Disabling Zero Code Suppression (ZCS)
The SPI-2213 collects statistics data and generates statistics files periodically.
The WSM collects these statistics files. A statistics file is composed of the header used to
indicate a statistics group and its detailed index (for example, a specific carrier, sector, CPU,
port, etc.) and the statistics data for that index.
In a statistics period, the statistics data for a specific index can become zero in a statistics
file in the following cases:
y When the index does not actually exist in the configuration.
y When the index exists in the configuration but its statistics data collected during that
period is zero.
Therefore, the Disabling ZCS function, which sets the zero data flag in the sub index
header, is provided to recognize the two cases separately.
