VDSL Commands

show controllers efm actual

Use this command to display the current values of the VDSL link on a specific VDSL port.

Syntax

show controllers efm interface-idactual {dsrserrs usrserrs txpower rxpower snr link}

interface-id- ID of the VDSL port.

dsrserrs - Displays the downstream Reed-Solomon errors on the VDSL port.

link - Displays the VDSL link status of the VDSL port.

rxpower - Displays the local receive power (dBm/Hz) on the remote customer premises equipment (CPE) port.

snr - Displays the signal-to-noise ratio (SNR) on the VDSL port.

txpower - Displays the remote transmit power (dBm/Hz) on the VDSL port.

usrserrs - Displays the upstream Reed-Solomon errors on the VDSL port.

Default Setting

None

Command Mode

Privileged EXEC

Command Usage

SNR and Reed-Solomon error information display the quality of the VDSL link.

The SNR represents the upper limit of received signal-to-noise ratio that the switch will handle before disconnecting from the remote CPE.

The Reed-Solomon errors show the number of errors detected and corrected in the data being received on, and transmitted from, the VDSL ports. Reed-Solomon errors are the result of noise exceeding the noise margin.

Example

The following example displays the current values of the VDSL link on VDSL switch port 2.
