ONFIGURATION

Use the Administration > OAM > Interface page to enable OAM
functionality on the selected port. Not all CPEs support operation and
maintenance functions, so OAM is therefore disabled by default. If a CPE
supports OAM, this functionality must first be enabled on the connected
port to gain access to the configuration functions provided under the OAM
menu.
