Table 4 Performance Counters, their Respective Counting Intervals, and the Type of Data
Stored in the NE
Performance counter
Counting Intervals
Data stored in the NE
Adaptive Modulation states 15 minutes (default) or 24
hours intervals
The seconds spent in each
modulation as well as the
number of changes between
modulations are counted
G.826
The following performance
counters are used by G.826:
• Errored Seconds (ES)
• Severely Errored Seconds
(SES)
•
Background Block Error
(BBE) (only structured
interfaces)
• Unavailable Seconds (UAS)
• Elapsed time
• Background Block
Continuous (default), 15
minutes, or 24 hours intervals
•
Continuous data
• The current 15 minutes and
the previous 96×15 minutes
• The current 24 hours and
the previous 30×24 hours
7.5.3 Ethernet Performance Counters
The following Ethernet performance counters are available:
Bandwidth Utilization — Measures bandwidth utilization per port or per Traffic
Class on the WAN port.
• Average, Max, and Min bandwidth
• Bandwidth utilization histogram
Queuing Delay
— Measures queuing delay per port or per Traffic Class on
the WAN port.
• Average, Max, and Min delay
• Delay histogram
RMON — Performance counters as specified in IETF RFC 2819.
• Separate counters for LAN and WAN ports
• RMON counter statistics are sampled every 900 seconds (15 minutes)
and stored in 96 intervals.
