Retrieve Statistics
Retrieve Statistics
Use the
stats
command to display statistics on Cisco 67x activities. The statistics
provided by the
stats
command varies on the application or interface selected. To
retrieve Cisco 67x statistics:
Step 1
To see a list of applications and interfaces that provide status, enter:
stats ?
Step 2
To display specific statistics, for example, for the wan0 interface, enter:
stats wan0
Step 3
To exit CBOS, enter:
quit
Interpret Statistics
Use the
stats wan0
command to retrieve certain key statistics regarding ADSL
performance of your Cisco 67x. A sample output appears below:
cbos#
stats wan0
Physical WAN Port 0 Statistics
# of dropped cells:0 # of invalid cells:0
# of CRC errors:0
# of processed OAM loopback cells
segment:0 end-to-end:0
The statistics displayed by the
stats wan0
command are:
•
CRC Errors—Number of CRC errors. CRC errors might occur when the ATM
traffic rate is faster than the ADSL rate, causing ATM cells to be dropped.
This corrupts the AAL5 logical packets. CRC errors might also be an
indication of excessive noise on the DSL line.
•
Operation, Administration, Maintenance (OAM) Loopback Cells—The
Cisco 67x supports the OAM-F5 loopback cell to verify end-to-end ATM
network connectivity. The OAM-F5 loopback cell is generated by a
network-side system, such as a Cisco 7200 series router, a Cisco 6400
