Use the OAM tab of the PVC Advanced Settings dialog box to define:
• The number of loopback cell responses that move the PVC to the down or up state.
• The number of alarm indication signal/remote defect indication (AIS/RDI) cells that move the PVC
to the down or up state.
• The number and frequency of segment/end continuity check (CC) activation and deactivation
requests that are sent on this PVC.
For more information, see Defining OAM Management on ATM PVCs, page 59-53.

Element Description
Retry settings
Enable OAM Retry When selected, OAM management settings can be defined.
When deselected, OAM management settings cannot be defined.
Note If Enable OAM Management is deselected in the OAM-PVC
tab, these settings are saved in the device configuration but are
not applied.
Down Count The number of consecutive, unreceived, end-to-end loopback cell
responses that cause the PVC to move to the down state. The default is
3.
Up Count The number of consecutive end-to-end loopback cell responses that
must be received in order to move the PVC to the up state. The default
is 5.
Retry Frequency The interval between loopback cell verification transmissions in
seconds. The default is 1 second.
If a PVC is up and a loopback cell response is not received within the
specified interval (as defined in the Frequency field of the PVC-OAM
tab), loopback cells are transmitted at the frequency defined here to
verify whether the PVC is down. If the number of consecutive cells that
do not receive a response matches the defined down count, the PVC is
moved to the down state.
