Accton Technology VS4512 Vdsl Port Link Status, Command Attributes General Status, PMD1 Status

	VDSL Configuration
The following example shows rate adaption enabled for port 1.
Console#config
Console(config)#interface ethernet 1/1	4-84
Console(config-if)#efm rate-adapt	4-108
Console(config-if)#end
Console#

The following example configures VDSL port 1 with an upstream noise margin of 6, and a downstream noise margin of 6.

Console#config
Console(config)#interface ethernet 1/1	4-84
Console(config-if)#efm noise-margin 6 6	4-107
Console(config-if)#end
Console#

The following example configures VDSL port 1 with:

•M - downstream value: 16, Upstream value: 8

•I - downstream value: 8, Upstream value: 8

Console#config
Console(config)#interface ethernet 1/1							4-84

VDSL Port Link Status

Command Attributes

•General Status

-Link – Shows the status of the VDSL link.

-Noise Margin – To ensure a stable link, you should add a margin to the theoretical minimum Signal-to-noise ratio (SNR). For details see “VDSL Port Configuration” on page 3-58.

Range: 0-9 dBm. Default: 0 dBm

•PMD1 Status

-SNR (dB) –The signal-to-noise ratio of the VDSL line.

-Downstream Rate (Mbps) – The rate at which data is transmitted from the switch to the CPE.

-Upstream Rate (Mbps) – The rate at which data is transmitted from the CPE to the switch.

1 Physical Media Dependent
