SLM-5650A Satellite Modem
Revision 10
Appendix E E–54 MN-SLM-5650A
Tx Collision Frames
The counters provided in this table are applicable in half-duplex only.
Column Description
Port
This is the corresponding Ethernet port on the NP Interface and, when in BPM
Mode, the Base Modem’s J5 Ethernet port.
Collision
This is the number of Collision events seen by the GMAC, not including those
controls in a single, Multiple, Excessive or Late.
Late Collision
This is the number of times a collision is detected later than 512 bits-times into
the transmission of the frame.
Single Collision
This is the total number of successfully transmitted frames that experienced
exactly one collision.
Multiple Collision
This is the total number of successfully transmitted frames that experienced
more than one collision.
Maximum Collision
This is the number of frames dropped in the transmit GMAC because the
frame experienced 16 consecutive collisions.
Tx Discarded/Filtered
Column Description
Port
This is the corresponding Ethernet port on the NP Interface and, when in BPM Mode,
the Base Modem’s J5 Ethernet port.
Discarded
This is the total number of frames received with either FCS errors or Tx Maximum
Collision frames.
Filtered Currently not implemented.
