Chapter 15 Performance Monitoring
15.5.3 ML-Series Ethernet Card Performance Monitoring Parameters
15.5.3.2 ML-Series POS Ports Window
The POS Ports window lists PM parameter values for each POS port on the card. 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 15-22 defines the ML-Series Ethernet card POS Ports parameters.
Rx FCS Errors Number of packets with a Frame Check Sequence (FCS) error.
Rx Runts Total number of frames received that are less than 64 bytes in length
and have a CRC error.
Rx Jabbers Total number of frames received that exceed the maximum
1548 bytes and contain CRC errors.
Rx Align Errors Number of received packets with alignment errors.
Tx Bytes Number of bytes transmitted since the last counter reset.
Tx Packets Number of packets transmitted since the last counter reset.
Tx Unicast Packets Number of unicast packets transmitted.
Tx Multicast Packets Number of multicast packets transmitted.
Tx Broadcast Packets Number or broadcast packets transmitted.
Tx Giants Number of packets transmitted that are greater than 1548 bytes in
length.
Tx Collisions Number of transmitted packets that collided.
Port Drop Counts Number of received frames dropped at the port level.
Rx Pause Frames Number of received pause frames.
Rx Threshold Oversizes Number of received packets larger than the ML-Series remote
monitoring (RMON) threshold.
Rx GMAC Drop Counts Number of received frames dropped by MAC module.
Tx Pause Frames Number of transmitted pause frames.

Rx Normal Packets Number of packets between the minimum and maximum packet size
received.
Rx Shorts Number of packets below the minimum packet size received.
Rx Runts Total number of frames received that are less than 64 bytes in length
and have a CRC error.
