Release Information

Statement introduced before JUNOS Release 7.4.

Description

For ATM encapsulation only, configure Operation, Administration, and Maintenance (OAM) F5 loopback cell count thresholds. Not supported on ATM-over-SHDSL interfaces.

For ATM2 IQ PICs only, configure OAM F4 loopback cell count thresholds at the [edit interfaces interface-name atm-options vpi vpi-identifier] hierarchy level.

Options

down-count cells—Minimum number of consecutive OAM F4 or F5 loopback cells lost before a VC is declared down.
up-count cells—Minimum number of consecutive OAM F4 or F5 loopback cells received before a VC is declared up.

Usage Guidelines

See Configuring the ATM OAM F5 Loopback Cell Threshold.
