Parameter frequency: Time interval to send operations, administration, and maintenance (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.

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.

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.

Use the undo oam frequency command to disable the transmission and 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.

The oam frequency command is not applicable to the secondary PVCs of a PVC group.

Example # Enable OAM F5 Loopback detection on PVC 1/32, with the period of 12 seconds. And set the retransmission detection up-countas 4, down-countas 4 and retransmission period as 1 second.
