304CHAPTER 19: ATM CONFIGURATION COMMANDS

mechanism used by PVC is FIFO. You can use the fifo queue-lengthcommand in the PVC view to change its queue length.

n The effect of this command applies to ATM main interface and sub-interface simultaneously.

Example # Set the MTU of ATM interface atm 1/0 to 1492 bytes.

<Sysname> system-view

[Sysname] interface atm 1/0

[Sysname-Atm1/0] mtu 1492

oam ais-rdi

Syntax

oam ais-rdi up up-countdown down-count

 

undo oam ais-rdi

View

PVC view, ATM class view

Parameter

up-count: Period (in seconds). A PVC goes up if no alarm indication signal/remote

 

defect indication (AIS/RDI) alarm cell is received in the period specified by this

 

argument. The value range of this argument varies with device model.

 

down-count: Number of AIS/RDI alarm cells. A PVC goes down if the number of

 

the successive AIS/RDI alarm cells received reaches the number specified by this

 

argument. The value range of this argument varies with device model.

Description

Use the oam ais-rdicommand to modify the parameters related to AIS/RDI alarm

 

cell detection.

 

Use the undo oam ais-rdicommand to restore the default.

 

By default, AIS/RDI alarm cell detection is enabled, which means a PVC goes down

 

if the number of successive AIS/RDI alarm cells received reaches that specified by

 

the down-countargument, and it goes up if no AIS/RDI alarm cell is received in a

 

period specified by the up-countargument.

 

Note that the oam ais-rdicommand is not applicable to the secondary PVCs of a

 

PVC group.

n

The primary PVC of a PVC group is the PVC based on which the PVC group is

created.

 

Second PVCs are created in PVC groups.

Example

# Configure the AIS/RDI alarm detection parameters for PVC 1/32, setting both

 

up-count and down-count to 5.

 

<Sysname> system-view

 

[Sysname] interface atm 1/0

 

[Sysname-Atm1/0] pvc 1/32

 

[Sysname-atm-pvc-Atm1/0-1/32] oam ais-rdi up 5 down 5
