Chapter 27 Alarms and Statistics
Trunk Statistics
Trunk Statistics
The following are the statistics that are collected on trunks at several different levels:
•
Physical line statistics apply to each physical port. In the case of IMA trunks, the physical line
statistics are tallied separately for each T1 port.
On the both the BPX and the IGX, physical line statistics are displayed on the dspphyslnstats ,
dspphyslnstathist , and dspphyslnerrs screens. These commands accept only physical line numbers
(that is: slot.port).
•
Logical trunk statistics refer to counts on trunks that are visible to users as routing entities. This
includes physical trunks and virtual trunks.
Logical trunk statistics are displayed on the dsptrkstats , dsptrkstahist , and dsptrkerrs screens.
These commands accept only logical trunk numbers and display only logical trunk statistics.
•
VI statistics are a subset of the logical trunk statistics.
• Queue statistics are a subset of the logical trunk statistics.
•
Channel statistics are not polled by software on trunks. However, they are available if you use the
debug command
dspchstats .
• Counter statistics use the dspcntrstats command to display in real-time all counter statistics of
specified entity.
Usr Line Loop Specifies that the line is looped. Use the dellnlp command to clear the loop. Both working
and protection lines are looped when an APS line is looped.
APS Standby Line
Alarms Specifies that the APS alarms are also shown unless there is a higher priority APS alarm
(those above) masking the standby line alarm. The APS standby alarms are the integrated
line alarms reported by the standby line in the BXM Line Alarms message (0x55). If one
of the alarms are shown, there is a problem with the standby line:
• Rmt Sec Trc Fail
•
Rmt Path Trc Fai
• Path Yellow
•
Path AIS
•
Loss of Pointer
•
Loss of Cell
• Remote Framing
•
Frame Sync Alarm
• Remote (YEL)
•
AIS (BLU)
•
Loss of Frm (RED)
•
Loss of Sig (RED)
Troubleshoot the line using standard line fault-isolation procedures.
