(OAM) F5 Loopback cells, in seconds, and the range of the value is 1 to 600.
(OAM) F5 Loopback cells, in seconds, and the range of the value is 1 to 600.
up-count: Number of OAM F5 Loopback cells. A PVC goes up only when the
number of the OAM F5 Loopback cells successively and correctly received reaches
the number specified by this argument. This argument ranges from 1 to 600. The
system default is 3.

system default is 3.
down-count: Number of OAM F5 Loopback cells. A PVC goes down only when
the number of the successive OAM F5 Loopback cells not received reaches the
number specified by this argument. This argument ranges from 1 to 600. The
system default is 5.
the number of the successive OAM F5 Loopback cells not received reaches the
number specified by this argument. This argument ranges from 1 to 600. The
system default is 5.
retry-frequency: Interval (in seconds) to send OAM F5 Loopback cell in
retransmission detection before PVC status changes. This argument ranges from 1
to 1,000. The system default is 1.

Description
Use the oam frequency command to enable the transmission and
retransmission detection of OAM F5 Loopback cell, as well as to modify the related
parameters.
retransmission detection of OAM F5 Loopback cell, as well as to modify the related
parameters.
Use the undo oam frequency command to disable the transmission and
retransmission detection of the cell.
retransmission detection of the cell.
By default, OAM F5 Loopback cell transmission is disabled, but if an OAM F5
Loopback cell is received, it should be responded.
Loopback cell is received, it should be responded.
The oam frequency command is not applicable to the secondary PVCs of a PVC
group.
group.
Example
# Enable OAM F5 Loopback detection on PVC 1/32, with the period of 12
seconds. And set the retransmission detection up-count as 4, down-count as 4
and retransmission period as 1 second.
