For ATM encapsulation only, configure the OAM F5 loopback cell period. Not supported on ATM-over-SHDSL interfaces.

For ATM2 IQ PICs only, configure OAM F4 loopback cell period at the [edit interfaces interface-name atm-options vpi vpi-identifier] hierarchy level.


If you omit this statement, OAM F5 loopback cells are not originated, but the interface still responds if it receives OAM F5 loopback cells.


disable—Disable OAM loopback cell transmit feature.

seconds—OAM loopback cell period.
