I suppose if you configure an ATM interface with only one PVC and you don't subinterface, OAM would do little good, nor harm I might add. > > I forget the exact situation, but I was working with a customer on an issue, > and the customer brought up OAM, and my own reading suggested it wasn't a > bright idea.

If so, OAM > is more of a carrier thing? I is definately not a carrier thing. The loss of OAM cells causes the subinterface, PVC, to go down though not in shutdowm state. This is very useful, even mandatory, when doing certain backup configs and HSRP tracking. Without OAM your subinterface is up regardless of the state of the connection on the other side of the PVC. The physical interface is indicative of the status of you connection to the ATM switch. OAM allows for the status of the PVC.
