Checking status of physical interface
The Physical-Status subprofile provides read-only information about the physical interface.
The interface runs a continuous bit-error-rate test (BERT) over unused bandwidth, so bit-error
counts are always available without explicitly running a BERT and disrupting data
transmission. Integrated BERT results are displayed by the Accum-Bit-Err, Num-Sec-Valid,
and Num-Sec-Invalid parameters.
Following are the Physical-Status parameters shown with settings for an active interface:
[in AL-DMT-STAT/{ shelf-1 slot-3 4 }:physical-status]
if-group-index = 0
unit-type = coe
dev-line-state = port-up
up-stream-rate-fast = 0
down-stream-rate-fast = 0
up-stream-rate-interleave = 288000
down-stream-rate-interleave = 3200000
up-stream-latency = interleave
down-stream-latency = interleave
firmware-ver = 0047
ansi-adsl-ver = 4
initial-adsl-ver = 2
hardware-ver = 9
modem-hw-state = init-ok
accum-bit-err = 0
num-sec-valid = 0
num-sec-invalid = 0

Parameter
Description
IF-Group-Index
Indicates the SNMP interface group index of the line.
Unit-Type
Indicates the operating mode (should always be COE).
Dev-Line-State
Indicates the current state of the interface. Valid values are:
•
down
—Either there is no connection or the interface is
disabled.
•
activation
—Interface is trying to train but not
detecting a modem on the other end.
•
training
—Training with a modem on the other end.
•
port-up
—Interface is successfully trained up.
•
failed
—Interface failed training (usually a log
message gives the reason).
•
loopback
—Interface is in special loopback test mode.
Up-Stream-Rate-Interleave
Indicates the upstream data rate in bps when latency is
interleave
. Zero means that latency is set to
fast
or the
data rate is unknown.
