COMMAND LINE INTERFACE

show controllers efm interface-id 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.

•actual - Displays the VDSL port current status, which might not be the same as the administratively configured settings.

•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) ratio 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 displays 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.
