CISCO-WAN-FR-CONN-STAT-MIB

The MIB module for frame relay connection statistics. Terminologies Used: SIW - Frame-Relay-to ATM Service Interworking FECN - Forward Explicit Congestion Notification. The FECN bit in Frame Relay header communicate network congestion to the endpoint in the forward direction. BECN - Backward Explicit Congestion Notification. The BECN bit in Frame Relay header communicate network congestion to the endpoint in the backward direction. DE - Discard Eligibility. The DE bit in Frame Relay header communicates the loss priority. A marked frame with a DE bit value of 1 is considered less important than other frames in transmission and should be discarded before frames with a DE bit value of zero. Tagged - Some of the statistics objects described in this MIB are applicable where the information is Set by the Switch/Service-Module. These objects contain word 'Tagged' in the name. For example : 'rcvFramesTaggedFECN'; This is the counter where FECN is set by the Switch in the frame received from the network. FECN was not set in the frame from the Network. The bit Set by the switch on an incoming or outgoing frame is called 'tagged' in this mib.
