Statistics
This report displays ADSL statistics.
overrun
Discarded received packets due to the internal 
Received Packet Ring Pool are full; therefore no 
incoming packets could be processed.
Sent Packet Information
packets sent
Total Ethernet packets sent.
discarded, TX ring full
Discarded outgoing packets due to internal 
Transmitted Packet Ring Pool Buffers are full. Could 
not process any outgoing packets.
discarded, bad pkt
Length of outgoing packets is larger than the 
maximum length of this interface. 
discarded, TX error
No. of discarded transmitted packets due to:
heartbeat lost
No. of transmitting Heartbeat (signal-quality error) 
packets lost/errors.
deferred
A count of frames for which the first transmission 
attempts on a particular interface is delayed because 
the medium is busy. The count represented by an 
instance of this object does not include frames 
involved in collisions.
late collision
Discarded transmitted frames because a collision 
occurred. No. of times that a collision is detected on a 
particular interface later than 512 bit-times into the 
transmission of a packet.
excessive collision
A count of frames for which transmission on a 
particular interface fails due to excessive collision
carrier sense lost
No. of times that the carrier sense condition was lost 
or never asserted when attempting to transmit a frame 
on a particular interface. The count represented by an 
instance of this object is incremented at most once per 
transmission attempt, even if the carrier sense 
condition fluctuates during a transmission attempt.
underrun
DMA underrun. Discarded outgoing packets because 
there are no packets waiting in the buffer.
transmitter resets
No. of transmitted packets after an error occurred
Parameter
Description

Description
Operational Seconds
Total kernel time (in seconds) link was operational.
Downstream SNR Margin
Current rate of downstream signal-to-noise ratio 
margin.
Downstream Attenuation
Current rate of downstream attenuation.
Upstream Attenuation
Current rate of upstream attenuation.
Near-End FEC
Count of near-end forward error correction.
