4.7 Inspect 10G Ethernet Interface Statistics
Description
Once the DAG 6.1S card has been configured for PoS mode, the 10G
Ethernet interface statistics are inspected to check the card is locked to the
data stream.
dag@endace:~$ dagsix -d dag0 -si
The tool displays a number of status bits that have occurred since last
reading. The following example shows the interval is set to one second via
the
-i
option.
For LAN mode, the following statistics are available.
LAN Statistics
RAI
Receive Alarm Indication. The optics report a
receive error. One or more of the following two bits
will also be set.
RLE
Receive Lock Error. The optics report a failure in
clock recovery from the received signal.
RPA
Receive Power Alarm. The optics report insufficient
optical input power (<-30dBm).
LOS
Loss Of Signal. The framer reports there is either no
signal at receiver, or optical signal strength is too
low to be recognized.
LOC
Loss Of Clock. The framer is not receiving a valid
clock from the optics.
LOF
Loss Of Frame. The framer has asserted OOF for
more than 3 milliseconds.
BER
High Bit Error Rate detected, check optical level.
LFT
Local Fault, signal from peer is not being received
correctly.
RFT
Remote Fault, peer is not receiving a signal
correctly.
FCS_ERR
Number of Ethernet FCS errors since last reading.
BAD_PACKET
Number of errored packets received since last
reading.
GOOD_PACKET
Number of correct packets received since last
reading.
RXF
Receive Fifo Errors. Framer receive FIFO errors
since last reading.
