Oam Frequency - H3C SR8800 Command Reference Manual

When you configure OAM CC on a PVC, configure one end of the PVC as the CC cell source and the
other end as the CC cell sink.
On an OAM CC-enabled PVC, if the detecting end fails to receive CC cells within 3 seconds, the state
of the PVC changes to down and will change to up only after CC cells or packets are received again.
When disabling OAM CC on a PVC, make sure that the role of the PVC in continuity check is the same
as the one that has been enabled. For example, if you have enabled the PVC as both the CC cell source
and the sink, you should perform the undo oam cc end-to-end both command rather than the undo oam
cc end-to-end sink command to disable the function.
This command cannot be configured on the member PVCs in a PVC group.

Parameters
frequency: Interval in seconds for sending OAM F5 Loopback cells, in the range of 0 to 600. When the
interval is set to 0, no OAM F5 loopback cells are sent.
up up-count: Specifies that the PVC goes up when the number of successive OAM F5 loopback cells
received correctly reaches the value specified by the up-count argument. The value range for the up-count
argument is 1 to 600, and the default is 3.
down down-count: Specifies that the PVC goes down when the number of successive OAM F5 loopback
cells that it fails to receive reaches the value specified by the down-count argument. The value range for
the down-count argument is 1 to 600, and the default is 5.
retry-frequency retry-frequency: Specifies the interval (in seconds) at which OAM F5 loopback cells
should be transmitted to verify a change in the PVC state (up/down). The value range is 1 to 1000. The
default is 1.
Description
Use the oam frequency command to enable the transmission and retransmission detection of OAM F5
Loopback cells, as well as to modify the related parameters.
Use the undo oam frequency command to disable the transmission and retransmission detection of OAM
F5 Loopback cells.
