OAM settings
Enable OAM Management When selected, OAM loopback cell generation and OAM management
are enabled on the PVC.
When deselected, OAM loopback cells and OAM management are
disabled. However, continuity checks can still be performed.
Frequency The interval between loopback cell transmissions. Valid values range
from 0 to 600 seconds.
Segment Continuity Check settings
Segment Continuity Check The current configuration of OAM F5 continuity checks performed on
PVC segments:
•None—Segment continuity checks (CC) are disabled.
•Deny Activation Requests—The PVC rejects activation requests
from peer devices, which prevents OAM F5 CC management from
being activated on the PVC.
•Configure Continuity Check—Segment CCs are enabled on the
PVC. The router on which CC management is configured sends a
CC activation request to the router at the other end of the segment,
directing it to act as either a source or a sink.
Segment CCs occur on a PVC segment between the router and a
first-hop ATM switch.
