Configuring Layer 2 Circuit Cell-Relay Promiscuous Mode

By default, all incoming cells are mapped from a single VC to an external LSP. For ATM interfaces with Layer 2 circuit cell-relay transport mode and atm-ccc-cell-relay encapsulation, you can configure promiscuous mode. Promiscuous mode allows you to map all incoming cells from either an interface port or a VP to a single LSP without restricting the VCI number. You can map traffic from all 65,535 VCIs to a single LSP, or from all 256 VPIs to a single LSP. For promiscuous-mode configuration guidelines, see Configuring ATM Cell-Relay Promiscuous Mode.

Example: Configuring Layer 2 Circuit Cell-Relay Promiscuous Mode

Configure Layer 2 circuit cell-relay VP- and port-promiscuous mode:

VP-Promiscuous Mode



[edit interfaces]
at-0/1/0 {
encapsulation atm-ccc-cell-relay;


atm-options {
pic-type atm2;
cell-bundle-size 4;


promiscuous-mode {
vpi 0;
}


}




unit 0 {
encapsulation atm-ccc-cell-relay;
point-to-point;
vci 0.32;
}


}

Port-Promiscuous Mode



[edit interfaces]
at-0/1/0 {
encapsulation atm-ccc-cell-relay;


atm-options {
pic-type atm2;
promiscuous-mode;
}




unit 0 {
allow-any-vci;
}


}
