shdsl rate
Use shdsl rate to set the single-pair interface rate for an EFM interface.
Use undo shdsl rate to restore the default.

Parameters
rate: Specifies the maximum single-pair rate for the EFM interface. The value range is 192 kbps to 5696
kbps.
auto: Specifies the auto-negotiation mode.
Usage guidelines
The maximum downlink rate might not reach the specified rate as restricted by the CO equipment and
line conditions. If you select the auto mode, CPE and CO can negotiate a rate commensurate with the
current line condition during the activation process. If fixed rates are set at both ends, the two parties
negotiate a rate. In case the lower rate between them cannot be provided, the line cannot be activated.
Examples
# Set EFM 2/4/0 to operate in the auto-negotiation mode.
<Sysname> system-view
[Sysname] interface efm 2/4/0
[Sysname-EFM2/4/0] shdsl rate auto
shdsl snr-margin
Use shdsl snr-margin to set a target margin to SNR.
Use undo shdsl snr-margin to restore the default.
Syntax
shdsl snr-margin [ current current-margin-value ] [ snext snext-margin-value ]
undo shdsl snr-margin
