Command History
Usage Guidelines
Caution This command causes the port to retrain when you change the parameter.
Setting a parameter to its current value does not cause a retrain. If a port is training when you change
this value, the port untrains and retrains to the new value.
Examples In this example, the command sets the SNR margins of the default profile to 12 dB downstream and
6 dB upstream:
DSLAM# configure terminal
DSLAM(config)# dsl-profile default
DSLAM(config-dsl-prof)# dmt margin downstream 12 upstream 6
Related Commands None.
dmt-margin Enter the upstream and downstream SNR margins in decibels. The range is
0 to 15.
