Chapter 15 Performance Monitoring
15.6.3 ML-Series Ethernet Card Performance Monitoring Parameters
15.6.3.2 ML-Series POS Ports Parameters
The POS Ports window lists PM parameter values for each POS port on the card. The parameters
displayed depend on the framing mode employed by the ML-Series card. The two framing modes for the
POS port on the ML-Series card are HDLC and frame-mapped generic framing procedure (GFP-F). For
more information on provisioning a framing mode, refer to the Cisco ONS 15454 SDH Procedure Guide.
Auto-Refresh sets a time interval at which automatic refresh will occur. The PM values are a snapshot
captured at the time intervals selected in the Auto-Refresh field. Historical PM values are not stored or
displayed.
Table 15-12 defines the ML-Series Ethernet card POS Ports parameters for HDLC mode.
ifOutUcast Pkts Indicates the number of unicast packets transmitted.
ifOutMulticast Pkts Indicates the number of multicast packets transmitted.
ifOutBroadcast Pkts Indicates the number or broadcast packets transmitted.
dot3StatsAlignmentErrors Indicates the count of frames received on a particular interface that are
not an integral number of octets in length and do not pass the FCS check.
dot3StatsFCSErrors Indicates the count of frames received on a particular interface that are
an integral number of octets in length but do not pass the FCS check.
etherStatsUndersizePkts Indicates the total number of packets received that were less than
64 octets long (excluding framing bits, but including FCS octets) and
were otherwise well formed.
etherStatsOversizePkts Indicates the total number of packets received that were longer than
1518 octets (excluding framing bits, but including FCS octets) and were
otherwise well formed. Note that for tagged interfaces, this number
becomes 1522 bytes.
etherStatsJabbers Indicates the total number of packets received that were longer than
1518 octets (excluding framing bits, but including FCS octets), and had
either a bad FCS with an integral number of octets (FCS error) or a bad
FCS with a nonintegral number of octets (alignment error).
etherStatsCollissions Indicates the number of transmit packets that are collisions; the port and
the attached device transmitting at the same time caused collisions.
etherStatsDropEvents Indicates the number of received frames dropped at the port level.
rx PauseFrames Indicates the number of received Ethernet IEEE 802.3z pause frames.
mediaIndStatsOversize
Dropped
Indicates the number of received oversized packages that are dropped.
mediaIndStatsTxFramesToo
Long
Indicates the number of received frames that are too long. The maximum
is the programmed maximum frame size (for virtual storage access
network [VSAN] support); if the maximum frame size is set to default,
then the maximum is the 2112 byte payload plus the 36 byte header,
which is a total of 2148 bytes.
