Cisco ATM Frame Adapter If Vc Q Outq Mark Threshold

1.3.6.1.4.1.9.9.110.1.1.1.1.5

This object defines the Marking threshold applied to the Frame Relay - ATM interworking virtual circuit output queue, on the Frame Relay PAM. The output queue is in the direction of the ATM switch fabric to the Frame Relay/FUNI interface. If the fill level of the output queue for the Frame Relay - ATM interworking virtual circuit exceeds this threshold, the following will happen: 1. For frames coming into the Frame Relay - ATM interworking virtual circuit from the Frame Relay side, the frame will have the BECN bit set in the Frame Relay header before getting converted to cells and entering the ATM switch fabric. 2. For cells arriving from the ATM switch fabric side for this Frame Relay - ATM interworking virtual circuit, the corresponding frames will have the Forward Explicit Congestion Notification (FECN) bit set in the Frame Relay header upon exiting the Frame Relay interface. For FUNI - ATM interworking connections, the Congestion Notification (CN) bit gets set in the FUNI header. The threshold value is expressed as a percent-of-full. Setting this object to 100 effectively turns off the threshold.
