Monitoring Frame Relay

You can monitor Frame Relay interfaces using the show frame-relay commands:

• show frame-relay interface
• show frame-relay lmi
• show frame-relay map
• show frame-relay pvc
• show frame-relay subinterface
• show frame-relay summary

You can set a statistics baseline for Frame Relay interfaces, subinterfaces, and/or circuits using the baseline frame-relay command.

You can use the output-filtering feature of the show command to include or exclude lines of output based on a text string you specify. Refer to show Commands in ERX System Basics Configuration Guide, Chapter 2, Command Line Interface, for details.

If you do not specify an interface type for the appropriate show command, the output indicates whether a serial or POS interface is being displayed.

    baseline frame-relay interface

• Use to set a statistics baseline at the Frame Relay layer for HSSI, multilink Frame Relay, POS, serial or GRE tunnel interfaces, subinterfaces, and/or circuits.
• The system implements the baseline by reading and storing the statistics at the time the baseline is set and then subtracting this baseline whenever baseline-relative statistics are retrieved.
• Specify an interface or subinterface using the interface type and specifier. For more information, see Interface Types and Specifiers in ERX Command Reference Guide, About This Guide.
• Specify a circuit using the interface type and specifier and the dlci keyword and the dlci number.
• You cannot set a baseline for groups of interfaces, subinterfaces, or circuits. You must set baselines individually.
• When baselining is requested, the time since the last baseline was set is displayed in hours:minutes:seconds or days/hours format. If a baseline has not been set, the message "No baseline has been set" is displayed instead.
• The regular interface statistics and LMI statistics for interfaces are subject to the same baseline timestamp. You cannot set separate baselines.
• Use the optional delta keyword with Frame Relay show commands to specify that baselined statistics are to be shown.
• Example

host1#baseline frame-relay interface serial 2/0:1/1

host1#show frame-relay interface delta

Frame relay interface 2/0:1/1, status is lowerLayerDown

Number of interface down transitions is 0

Time since last status change 21:06:34

The FECN bit is set by a network to notify the user that congestions may be experienced by data traffic 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.
• Out FECN pkts - number of packets transmitted with the FECN bit set
• In BECN pkts - number of packets received with the backward explicit congestion notification (BECN) bit set. The BECN bit is set by a network to notify the user that congestions may be experienced by data traffic 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.
• Out BECN pkts - number of packets transmitted with the BECN bit set
• In DE pkts - number of packets received with the discard eligibility (DE) bit set. When the DE bit is set, it indicates that the frame should be discarded in preference to other frames without the DE bit set. The DE bit may be set by the network or the user. Once it is set, it cannot be reset by the user.
• Out DE pkts - number of packets transmitted with the DE bit set
• Dropped packets - number of dropped packets
