config vdsl_ports
Parameters downstream – Downstream data transmission
speed speed, specify speed as Mode 0, 512 Kbps
or from 1 – 15 Mbps.
upstream – Upstream data transmission speed
speed, specify speed as Mode 0, 512 Kbps or
from 1 – 15 Mbps.
Mode 0 – This is the default setting for VDSL
ports. It specifies a downstream speed of 4Mbps
and upstream speed of 1Mbps.
rate adaptive mode – When the VDSL rate
adaptive mode is enabled, the switch
automatically senses line condition and adjusts
downstream and upstream speeds if the set rate
cannot be maintained. The default setting will
set speed to Mode 0 when a rate can no longer
be supported.
optimum – When rate adaptive mode is enabled,
this sets speed to Mode 0 but then tests the
downstream and upstream speed and raises
each incrementally to achieve the best
performance level.
state – Enable or disable the listed ports.
learning – When learning is enabled, MAC
addresses are automatically added to the
forwarding table. When disabled, any additions
to the forwarding table must be entered
manually.
Restrictions This is for VDSL applications only. Requires
installation of DES-7010 Ethernet over VDSL
module.
