The atm-ping OAM loopback feature can be enabled on an ATM SAP for a period of time
configured through the interval and the send-count parameters. When the ATM SAP terminates on
IES or VPRN services, a failure of the loopback state machine does not bring down the Layer 3
interface. Only receiving AIS/RDI OAM cells or entering the AIS/RDI state brings down the
Layer 3 interface.
The atm-ping OAM loopback feature can be also be enabled on a continuous basis on an ATM
SAP terminating on IES or VPRN services. When the loopback state machine fails, the Layer 3
interface is brought down.
The ATM OAM loopback parameters must be first enabled and configured in the config>system>
atm>oam context and then enabled in the
IES or VPRN service interface SAP atm oam
context.
Refer to the IES and VPRN sections of the 7750 SR OS Services Guide for further information.
