it considers the PVC as normal. If the sender fails to receive a certain number of consecutive OAM cells
sent by itself, the PVC is considered as faulty.
Two approaches are available for implementing the OAM F5 Loopback function: manual (OAMPing)
and auto (OAM Frequency). In the OAMPing approach, you need to send OAM cells manually; this
approach is usually used for diagnosis. In the OAM Frequency approach, you need to configure an ATM
interface to send OAM cells regularly at a certain interval. The latter approach automatically checks link
status.
OAM continuity check
When enabled, the OAM Continuity Check (CC) function periodically sends OAM cells to check
whether a connection is idle or has failed.
The OAM CC function works as follows on a PVC:
One side of the PVC sends OAM cells to its peer, which checks the connection status based on these
OAM cells.

Configuring an ATM interface
Depending on the actual networking environment and system requirements, you may be required to
modify certain parameters of an ATM interface.
Note that except the mtu command, which can be configured on a subinterface, the ATM settings in this
section must be modified in ATM main interface view, although they apply to the ATM main interface and
subinterfaces at the same time.
To configure an ATM interface:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter ATM main interface
view.
