For the show port [portlist|all|active] command, if the port is in the up state, the system will show some current
information on the ADSL link: Current working mode, current upstream/downstream rate, current noise margin,
and upstream/downstream attainable rate. If the port in the down state, the displayed information will be of little
use. For example (only one port 15:2 is in the up state):
3P@C(config)#show port active
--------------------------------------------------------------------------
Port:<15:2> 's Current Value Information
Link state : Up Port state : enabled
Port Default VLAN ID : 2881 Port VLAN name : dsl2881
Remote modem connection : YES
Service Mode : G.dmt Channel Mode : Interleaved
DS Rate(Kbps) : 8064 US Rate(Kbps) : 1024
DS NoiseMargin(dB) : 12.00 US NoiseMargin(dB) : 7.00
DS Interleaved Delay(ms) : 16 US Interleaved Delay(ms) : 8
DS Attenuation(dB) : 32.50 US Attenuation(dB) : 23.5
DS Out Power(dB) : 7.60 US Out power(dB) : 12.40
DS Attainable Rate(Kbps) : 10400 US Attainable Rate(Kbps) : 1186
--------------------------------------------------------------------------
The parameters in the command are described below:
„ Link state: Whether the port is in the link state (up or down)
„ Port state: Whether the port is enabled or not. If the port is in the Disable state, the Link state
must be down.
„ Port Default VLAN ID: By default, each port belongs to the VLAN created by a system to
isolate the ports. This item indicates the ID of the VLAN where the port is located.
„ Port VLAN name: Name of the VLAN where the port is located
„ Remote modem connection: Whether the port is connected with a modem. If it is “yes”, it
indicates that the port is connected with a modem.
„ Service Mode: The working mode of the port (g.dmt, g.lite, or t1.413)
„ Channel Mode: The channel mode for port data transmission (Interleaved or Fast).
„
DS Rate(Kbps): Actual rate in the downstream direction (Kbps)
„ US Rate(Kbps): Actual rate in the upstream direction (Kbps)
„ DS NoiseMargin(dB): Actual noise margin in the downstream direction, that is, signal-to-noise
ratio. The greater it is, the better the link quality in the downstream direction is.
„ US NoiseMargin(dB): Actual noise margin in the upstream direction, that is, signal-to-noise
ratio. The greater it is, the better the link quality in the upstream direction is.
„ DS Interleaved Delay(ms): Actual interleaved depth in the downstream direction. It is used for
interleaved channels.
„ US Interleaved Delay(ms): Actual interleaved depth in the upstream direction. It is used for
interleaved channels.
„ DS Attenuation(dB): Link attenuation in the downlink direction. It is a link parameter calculated
from the ATU-R. The greater it is, the worse the link quality in the downstream direction.
„ US Attenuation(dB): Link attenuation in the uplink direction. It is a link parameter calculated
from the ATU-C. The greater it is, the worse the link quality in the upstream direction.
