IPmux-11 Ver. 2.00 Monitoring Performance 6-1

Chapter 6 Troubleshooting and Diagnostics

This chapter describes how to:

• Monitor performance

• Detect errors

• Handle alarms

• Troubleshoot problems

• Perform diagnostic tests.

6.1 Monitoring Performance

IPmux-11 provides powerful performance monitoring tools, which consist of the

following three levels:

• E1/T1 statistics – Status of the physical E1/T1 parameters (signal, framing, etc.)

• LAN statistics – Ethernet connection status (speed, duplex mode, bytes

transmitted & received, etc.)

• Bundle connection statistics – TDMoIP bundle connection status on the

Ethernet/IP network level.

Displaying E1/T1 Statistics

E1/T1 statistics refer to the physical status of the E1/T1 traffic reaching IPmux-11

from the adjacent E1/T1 device.

The E1 statistics parameters comply with the G.703, G.704, G.804, G.706, G.732,

and G.823 standards.

The T1 statistics parameters comply with the ANSI T.403, AT&T R62411, G.703,

G.704 and G.804 standards.

E1/T1 statistics are monitored and saved under consecutive intervals. Each interval

is 15 minutes long. There are 96 intervals, which represent the last 24 hours.

Whenever a new interval is started, the counters are reset to zero. The old interval

shows the total of events that occurred during its 15-minute period.

The current active interval is always marked as interval 0 (you will see that the

Time Since counter is running). The previous interval is marked as 1 and so on.

The E1/T1 statistic counters cannot be reset manually.
