Configuring the ATM OAM F5 Loopback Cell Threshold
For ATM1 and ATM2 IQ interfaces with an ATM encapsulation, you can configure the OAM F5 loopback cell threshold on VCs. This is the minimum number of consecutive OAM F5 loopback cells received before a VC is declared up, or the minimum number of consecutive OAM F5 loopback cells lost before a VC is declared down.
By default, when five consecutive OAM F5 loopback cells are received, the VC is considered to be up, and when five consecutive cells are lost, the VC is considered to be down. To modify these values, include the oam-liveness statement:
For a list of hierarchy levels at which you can include this statement, see oam-liveness.
The cell count can be a value from 1 through 255.
