Tx Valid Frames
Column
Description
Port
The corresponding Ethernet port on the NP Interface and, when in BPM Mode, the
base modem’s J5 Ethernet port.
Unicast
Number of valid unicast frames transmitted.
Broadcast
Number of valid broadcast frames transmitted.
Multicast
Number of valid multicast frames transmitted.
Pause
Number of PAUSE frames transmitted.
Tx Collision Frames
The counters provided in this table are applicable in half-duplex only.
Column
Description
Port
The corresponding Ethernet port on the NP Interface and, when in BPM Mode, the
base modem’s J5 Ethernet port.
Collision
The number of Collision events seen by the GMAC, not including those controls in a
single, Multiple, Excessive or Late.
Late Collision
The number of times a collision is detected later than 512 bits-times into the
transmission of the frame.
Single Collision
The total number of successfully transmitted frames that experienced exactly one
collision.
Multiple Collision
The total number of successfully transmitted frames that experienced more than one
collision.
Maximum Collision
The number of frames dropped in the transmit GMAC because the frame experienced
16 consecutive collisions.
Tx Discarded/Filtered
Column
Description
Port
The corresponding Ethernet port on the NP Interface and, when in BPM Mode, the
base modem’s J5 Ethernet port.
Discarded
The total number of frames received with either FCS errors or Tx Maximum Collision
frames.
Filtered
