Command Modes
FRF.5 connect submode
Command History
Usage Guidelines
In the default state, the DE bit in the Frame Relay header is set to 1 when one or more ATM cells belonging to a frame has its cell loss priority (CLP) field set to 1, or when the DE field of the Frame Relay service specific convergence sublayer (FR-SSCS) protocol data unit (PDU) is set to 1.
When the no de-bit map-clp command is entered, the FR-SSCS PDU DE field is copied unchanged to the Q.922 core frame DE field, independent of CLP indications received at the ATM layer.
Examples
The following example creates a connection that connects the virtual circuit (VC) group named friends to ATM PVC 0/32 and configures FR DE field mapping to match the ATM CLP field:
router(config)# vc-group friendsrouter(config-vc-group)# serial0 16 16router(config-vc-group)# serial0 17 17router(config-vc-group)# serial0 18 18router(config-vc-group)# serial0 19 19router(config)# interface atm3/0router(config-if)# pvc 0/32router(config-if-atm-vc)# encapsulation aal5mux frame-relayrouter(config)# connect vc-group friends atm3/0 0/32router(config-frf5)# de-bit map-clpRelated Commands
