Performance Reports
Use the Performance Statistics screen to access performance reports for the
DSU/CSU.
When the network interface is configured for ESF operation, network
performance is continuously monitored and maintained in two sets of aggregate
registers: Carrier Network Interface Registers (Telco) and User Network Interface
Registers (User). The User registers contain an extra status register (Status).
Registers are listed in Table 5-3. These registers are status registers that collect
performance data for the previous 24-hour period. Performance data is updated
in 15-minute intervals. After 15 minutes, the current interval is rolled over into a
set of accumulator registers that represent the previous 96 15-minute intervals for
the register. An interval total of how many of the 96 registers contain valid data is
also kept, as well as a 24-hour total for each accumulator register.
Port performance is continuously monitored and maintained in memory registers
when the port is configured to use EDL. The DSU/CSU maintains two sets of port
registers for each synchronous data port: far-end port registers and near-end port
registers. These registers are status registers that collect performance data for
the previous 8-hour period. Port data is updated in 15-minute intervals. After
15 minutes, the current interval is rolled over into a set of accumulator registers
that represent the previous 32 15-minute intervals for the register. An interval
total of how many of the 32 registers contain valid data is also kept, as well as a
8-hour total for each accumulator register.
You can reset the performance registers via the Clear Statistics selection on the
Performance Statistics screen.
