4-8 Monitoring Performance ASMi-54C LRS-102 Ver. 2.0
The information is accumulated continuously while the ASMi-54C operates, and is
automatically refreshed every few seconds.
You can clear the displayed statistics (that is, reset the displayed performance
monitoring counters) by typing C. This ensures that only fresh data is displayed, a
useful feature during troubleshooting.
³ To display the Ethernet port performance monitoring statistics:
1. Navigate to the Monitoring > Physical Layer > IO > Ethernet screen of the
desired module, and select the desired Ethernet port, ETH 1 or ETH 2.
2. On the Ethernet port screen, select Statistics.
3. You will see the Statistics screen for the selected Ethernet port. The screen
includes a large number of items and therefore it consists of three pages:
 To continue from the first page to the next page, type N (next)
 To return from the second page to the previous page, type P (previous).
Table 4-8 explains the statistics parameters.
The information displayed on the screen, which is accumulated continuously, is
automatically refreshed every few seconds. You can clear the displayed statistics
(that is, reset the displayed performance monitoring counters) by typing C. The
counters are also reset when the ASMi-54C is powered up.

Parameter Description
Rx Total Frames Total number of frames received through the corresponding Ethernet port
Rx Total Octets Total number of data octets carried by all frames received through the
corresponding Ethernet port
Rx Correct Frames Total number of good frames received through the corresponding Ethernet
port
Rx FCS Errors Total number of frames received by the corresponding Ethernet port which
has an invalid FCS, but met the following conditions:
• Frame data length is between 64 bytes, and 1518 or 1536 bytes
(depending on mode)
• Collision event has not been detected
• Late collision event has not been detected
Rx Jabber Errors Total number of frames received by the corresponding Ethernet port during
jabber (such frames are frames with a data field length exceeding 1518 or
1536 bytes, and also having invalid CRC)
Rx Fragments Errors Number of fragmented frames received at the corresponding Ethernet port (a
fragmented frame is a frame with a data field length less than 64 bytes and
invalid CRC, for which no collision event and no late collision event have not
been detected during its reception)
Rx Pause Frames Total number of pause frames (used for flow control) received through the
corresponding Ethernet port
