Viewing Frame Relay Statistics

The NMC-RX application allows you to view and monitor information about Frame Relay interfaces, subinterfaces, and circuits. Once you select a configured device, you can list the objects and request statistics.

To view statistics:

From the Device-wide Explorer, select Frame Relay, and click either Interfaces, Sub Interfaces, or Circuits.
Right-click, and select List All.

A list of all objects of the type you selected, which are configured on the device, appears in the list area.

Select an item in the list area, right-click, and select Statistics.

The appropriate Statistics tab appears. See the following sections for more information.

Interface and Subinterface Statistics

The Statistics tab for Frame Relay interface and subinterface statistics is shown. Table 73 describes the attributes.

Circuit Statistics

The Statistics tab for a Frame Relay circuit is shown. Table 74 describes the attributes.




 Table 74:  Frame Relay Circuit Statistics Attributes 

 Attribute
 Description

 Received FECN Frames

 Number of packets received with the forward explicit congestion notification (FECN) bit set
 NOTE: The FECN bit is set by a network to notify the user that data traffic may experience congestions in the direction of the frame carrying the FECN bit. The FECN bit is set by the network (not by the transmitting user), and there is no obligation for end systems to take any action regarding the FECN bit.


 Transmitted FECN Frames

 Number of packets transmitted with the FECN bit set
 NOTE: The FECN bit is set by a network to notify the user that data traffic may experience congestions in the direction of the frame carrying the FECN bit. The FECN bit is set by the network (not by the transmitting user), and there is no obligation for end systems to take any action regarding the FECN bit.


 Received BECN Frames

 Number of packets received with the backward explicit congestion notification (BECN) bit set
 NOTE: The BECN bit is set by a network to notify the user that data traffic may experience congestions in the opposite direction of the frame carrying the BECN bit. The BECN bit is set by the network, and there is no obligation for end systems to take any action regarding the BECN bit.


 Transmitted BECN Frames

 Number of packets transmitted with the BECN bit set
 NOTE: The BECN bit is set by a network to notify the user that data traffic may experience congestions in the opposite direction of the frame carrying the BECN bit. The BECN bit is set by the network, and there is no obligation for end systems to take any action regarding the BECN bit.


 Received Frames

 Number of incoming packets received on the circuit


 Transmitted Frames

 Number of outgoing packets transmitted on the circuit


 Received Octets

 Number of octets received on the circuit


 Transmitted Octets

 Number of octets sent


 Received DE Frames

 Number of packets received with the discard eligibility (DE) bit set
 NOTE: When the DE value is set, it indicates that the frame should be discarded in preference to other frames without the DE bit set. DE bit may be set by the network or the user. Once set, it cannot be reset.


 Transmitted DE Frames

 Number of packets transmitted with the DE bit set
 NOTE: When the DE value is set, it indicates that the frame should be discarded in preference to other frames without the DE bit set. DE bit may be set by the network or the user. Once set, it cannot be reset.


 Received Frames Discarded

 Number of inbound packets dropped
