215down down-seconds: Specifies the time (in seconds) within which the PVC goes down if it receivessuccessive AIS/RDI alarm cells. The value range for the down-seconds argument is 1 to 60 seconds.Usage guidelinesThe 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 bythe down-seconds argument.• A PVC comes up if no AIS/RDI alarm cells are received in the time period specified bythe up-seconds argument.Examples# Configure the AIS/RDI alarm detection parametersfor PVC 1/32, settingup-seconds to 5and down-seconds to 5. 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. system-view[Sysname] interface atm 2/4/0[Sysname-ATM2/4/0] pvc-group 2[Sysname-ATM2/4/0-pvc-group-2] pvc 1/33[Sysname-ATM2/4/0-pvc-group-2-pvc-1/33] oam ais-rdi up 5 down 5oam loopbackUse oam loopback to enable OAM F5 Loopback cell transmission and retransmission detection andmodify related parameters.Use undo oam loopback to disable OAM F5 Loopback cell transmission and retransmissiondetection.Syntaxoam loopback interval [ up up-count down down-count retry retries ]undo oam loopbackDefaultOAM F5 Loopback cell transmission is disabled.
