adsl inp
<portlist>[<usinp>[,<dsinp>]]
Sets the upstream (us) and downstream (ds) impulse
noise protection minimum setting on the specified
ADSL port(s). Sudden spikes in the line’s noise level
(impulse noise) can cause errors and result in lost
packets. Set the impulse noise protection minimum to
have a buffer to protect the ADSL physical layer
connection against impulse noise. This buffering
causes a delay that reduces transfer speeds. It is
recommended that you use a non-zero setting for real
time traffic that has no error correction (like
videoconferencing).
usinp: Sets the minimum upstream (us) impulse noise
protection setting. Use 0~3 to define a number of DMT
symbols. 0 = 0 DMT symbols, 1 = 0.5 DMT symbols, 2
= 1 DMT symbols, 3 = 2 DMT symbols.
dsinp: Sets the minimum downstream (ds) impulse
noise protection setting. Use 0~3 to define a number
of DMT symbols. 0 = 0 DMT symbols, 1 = 0.5 DMT
symbols, 2 = 1 DMT symbols, 3 = 2 DMT symbols.
H/H
adsl annexm show <portlist> Displays the Annex M feature setting for the specified
port(s).
M/L
adsl annexm enable <portlist> This command turns on the Annex M double upstream
feature on the specified ADSL2/2+ port(s). This has
the upstream connection use tones 6 to 63.
H/H
adsl annexm disable <portlist> This command turns off the Annex M double upstream
feature on the specified ADSL2/2+ port(s).
H/H
adsl queuemap set <priority>
<queue-level>
IEEE 802.1p defines up to 8 separate traffic types by
inserting a tag into a MAC-layer frame that contains
bits to define class of service. Frames without an
explicit priority tag are given the default priority of the
ingress port. Use this command to configure the
priority level-to-physical queue mapping.
queue-level: The device has 4 physical queues that
you can map to the 8 priority levels for outgoing
Ethernet traffic. The device has 8 physical queues that
you can map to the 8 priority levels for outgoing DSL
traffic. Traffic assigned to higher index queues gets
through the device faster while traffic in lower index
queues is dropped if the network is congested.
H/H
adsl queuemap show Displays the xDSL priority level to physical queue
mapping.
M/L
adsl dsbcast enable <portlist>
<vlanlist>
Enables downstream broadcast packets sent to
specified VLANs on specified ports.
M/
H
adsl dsbcast show <portlist> Shows downstream broadcast settings on specified
xDSL port(s).
L/L
adsl dsbcast disable <portlist>
<vlanlist>
Disables downstream broadcast packets sent to
specified VLANs on specified ports.
M/
H
adsl sra enable <portlist> Turns on Seamless Rate Adaptation (SRA) ADSL2+ on
the specified port(s).
H/H
