Oam Loopback - H3C MSR810 Command Reference Manual

down down-seconds: Specifies the time (in seconds) within which the PVC goes down if it receives
successive AIS/RDI alarm cells. The value range for the down-seconds argument is 1 to 60 seconds.
Usage guidelines
The system uses a 1-second timer to detect AIS/RDI alarm cells.
• A PVC goes down if it receives successive AIS/RDI alarm cells in the time period specified by
the down-seconds argument.
• A PVC comes up if no AIS/RDI alarm cells are received in the time period specified by
the up-seconds argument.
Examples
# Configure the AIS/RDI alarm detection parameters for PVC 1/32, setting up-seconds to 5
and down-seconds to 5.
<Sysname> system-view
[Sysname] interface atm 2/4/0
[Sysname-ATM2/4/0] pvc 1/32
[Sysname-ATM2/4/0-pvc-1/32] oam ais-rdi up 5 down 5
# Configure the AIS/RDI alarm detection parameters for PVC 1/33 of PVC-group 2,
setting up-seconds to 5 and down-seconds to 5.
