list measurements clan ppp
Use list measurements clan ppp to list a 24-hour history of important
packet-level statistics. Use the history to review LAN performance characteristics.
For example:
■
Invalid frames show the number of frames that are misaligned.
■
CHAP failures (Challenge Handshake Authentication Protocol) show the
number of attempts for ppp authentication that failed.
■
High Cyclic Redundancy Check (CRC) detects and corrects errors on
every frame. Errors could suggest that the connection may be “noisy.”
The 24-hour history gives the ability to look back at these measures if the trouble
cleared.
Data is retrieved for 15-minute intervals for 24 hours for CRC, Invalid Frame and
Chap Failures for PPP connections. If the data cannot be retrieved for the 15
minute interval,
N/A
appears in the field. The change from the last inquiry and the
total are provided for each error count. After the occurrence of an “N/A,” the
change equals the total.
Total
The total value of the counter on the board
NOTE:
The counter value can be up to 11 digits long because of the
32-bit counter on the board. After the occurrence of an “N/A,”
the delta equals the total. Busyout or release of a board or a
port, the reset board command, and reseating the board all
clear the firmware counters.
Delta
The difference between the current and the previous sample
Collision Count
The error count for collisions on the ethernet
