6-8 Monitoring Performance RICi-622GE Ver. 1.0
Parameter Description
Collisions Total number of collisions that occurred
Discard Frames Total number of frames that were discarded even though no errors were
detected
TX
Total Frames Total number of correct frames transmitted
Total Octets Total number of octets transmitted, including framing characters
Correct Frames Total number of frames successfully transmitted
FCS Errors Total number of frames transmitted on a particular interface that are an integral
number of octets in length, but do not pass the FCS check. This count does not
include frames transmitted with Frame-Too-Long or Frame-Too-Short error.
Jabber Errors Total number of long frames transmitted with invalid CRC
Fragments Errors Total number of frames that are less than 64 octets in length (excluding framing
bits, but including FCS octets) and had either a bad Frame Check Sequence (FCS)
with an integral number of octets (FCS Error) or a bad FCS with a non-integral
number of octets (alignment error)
Pause Frames Total number of transmitted pause frames (indicate pause in transmission
needed due to congestion)
Undersized Frames Total number of transmitted short frames with size under 64 bytes and with valid
CRC
Oversized Frames Total number of transmitted long frames with size over 1518 bytes and with
valid CRC
Collisions Total number of occurred collisions
Discard Frames Total number of discarded frames
Errors Total number of transmission errors
Displaying SDH/SONET Statistics
RICi-622GE allows you to display SDH/SONET statistics for SOH, HVC, and LVC.
³ To display the SDH/SONET statistics for SOH:
1. From the Monitoring SDH/SONET menu (Monitoring > Physical Layer >
Statistics > SDH/SONET), select SOH to show the SOH statistics screen for
SOH-1 (
Figure 6-12 ). Table 6-3 describes the SDH/SONET statistic counters.
2. Type f to advance to the statistics for SOH-2.
