17When you configure OAM CC on a PVC, configure one end of the PVC as the CC cell source and theother 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 stateof 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 sameas the one that has been enabled. For example, if you have enabled the PVC as both the CC cell sourceand the sink, you should perform the undo oam cc end-to-end both command rather than the undo oamcc end-to-end sink command to disable the function.This command cannot be configured on the member PVCs in a PVC group.Examples# Enable OAM CC. system-view[Sysname] interface Atm 3/1/1[Sysname-Atm3/1/1] pvc 1/32[Sysname-atm-pvc-Atm3/1/1-1/32] oam cc end-to-end sinkoam frequencySyntaxoam frequency frequency [ up up-count down down-count retry-frequency retry-frequency ]undo oam frequencyViewPVC viewDefault level2: System levelParametersfrequency: Interval in seconds for sending OAM F5 Loopback cells, in the range of 0 to 600. When theinterval 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 cellsreceived correctly reaches the value specified by the up-count argument. The value range for the up-countargument 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 loopbackcells that it fails to receive reaches the value specified by the down-count argument. The value range forthe 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 cellsshould be transmitted to verify a change in the PVC state (up/down). The value range is 1 to 1000. Thedefault is 1.DescriptionUse the oam frequency command to enable the transmission and retransmission detection of OAM F5Loopback cells, as well as to modify the related parameters.Use the undo oam frequency command to disable the transmission and retransmission detection of OAMF5 Loopback cells.
