Configuring ATM Cell-Relay Accumulation Mode on an ATM1 PIC

You can configure an Asynchronous Transfer Mode (ATM) 1 PIC to use cell-relay accumulation mode. In this mode, the incoming cells (one to eight cells) are packaged into a single packet and forwarded to the label-switched path (LSP). At the edge router, this packet is divided in to individual cells and transmitted over the ATM interface.

Note: When you configure an ATM PIC to use cell-relay accumulation, all ports on the ATM PIC use cell-relay accumulation mode.

To configure an ATM PIC to use cell-relay accumulation mode, include the atm-cell-relay-accumulation statement at the [edit chassis fpc slot-number pic pic-number] hierarchy level:



[edit chassis fpc slot-number pic pic-number ]

atm-cell-relay-accumulation;

On a TX Matrix platform, include the atm-cell-relay-accumulation statement at the [edit chassis lcc number fpc slot-number pic pic-number] hierarchy level:



[edit chassis lcc number fpc slot-number pic pic-number]

atm-cell-relay-accumulation;
