(Most likely with RADIUS authentication.)Chap-Resp-sent—Response was sent for the challenge received.Closed—CHAP authentication is incomplete.Failure—CHAP authentication failed.Not-configured—CHAP is not configured on the interface.Success—CHAP authentication was successful.Date, time, and how long ago the interface went from down to up. The format is
Last flapped:year-month-day hour:minute:secondtimezone(hour:minute:secondago). For example,Last flapped: 2002-04-26 10:52:40 PDT (04:33:20 ago).Input rate in bits per second (bps) and packets per second (pps).
Time when the statistics for the interface were last set to zero.
Number of bytes and packets received and transmitted on the physical interface.
Input errors on the interface. The following paragraphs explain the counters whose meaning might not be obvious:
Errors—Sum of the incoming frame aborts and FCS errors.Drops—Number of packets dropped by the input queue of the I/O Manager ASIC. If the interface is saturated, this number increments once for every packet that is dropped by the ASIC's RED mechanism.Framing errors—Number of packets received with an invalid frame checksum (FCS).Giants—Number of frames received that are larger than the giant threshold.Runts—Number of frames received that are smaller than the runt threshold.Policed discards—Number of frames that the incoming packet match code discarded because they were not recognized or not of interest. Usually, this field reports protocols that the JUNOS software does not handle.L3 incompletes—Number of incoming packets discarded because they failed Layer 3 (usually IPv4) sanity checks of the header. For example, a frame with less than 20 bytes of available IP header is discarded.L2 channel errors—Number of times the software did not find a valid logical interface for an incoming frame.L2 mismatch timeouts—Number of malformed or short packets that caused the incoming packet handler to discard the frame as unreadable.HS link CRC errors—Number of errors on the high-speed links between the ASICs responsible for handling the router interfaces.Resource errors—Sum of transmit drops.Output errors on the interface. The following paragraphs explain the counters whose meaning might not be obvious:
Carrier transitions—Number of times the interface has gone fromdowntoup. This number does not normally increment quickly, increasing only when the cable is unplugged, the far-end system is powered down and up, or another problem occurs. If the number of carrier transitions increments quickly (perhaps once every 10 seconds), then either the cable, the far-end system, or the PIC is malfunctioning.Errors—Sum of the outgoing frame aborts and FCS errors.Drops—Number of packets dropped by the output queue of the I/O Manager ASIC. If the interface is saturated, this number increments once for every packet that is dropped by the ASIC's RED mechanism.Aged packets—Number of packets that remained in shared packet SDRAM so long that the system automatically purged them. The value in this field should never increment. If it does, it is most likely a software bug or possibly malfunctioning hardware.MTU errors—Number of packets larger than the MTU threshold.Resource errors—Sum of transmit drops.E1 media-specific defects that can render the interface unable to pass packets. When a defect persists for a certain amount of time, it is promoted to an alarm. Based on the router configuration, an alarm can ring the red or yellow alarm bell on the router, or turn on the red or yellow alarm LED on the craft interface. The following lists all possible alarms and defects. For complete explanations of most of these alarms and defects, see Bellcore Telcordia GR-499-CORE.
Active alarms and defects, plus counts of specific E1 errors with detailed information.
Seconds—Number of seconds the defect has been active.Count—Number of times that the defect has gone from inactive to active.State—State of the error. State other than OK indicates a problem.The E1 media-specific error types can be:
SEF—Severely errored framingBEE—Bit errorAIS—Alarm indication signalLOF—Loss of frameLOS—Loss of signalYELLOW—Errors at the remote site receiverBPV—Bipolar violationEXZ—Excessive zerosLCV—Line code violationPCV—Pulse code violationCS—Carrier stateFEBE—Far-end block errorLES—Line error secondsES—Errored secondsBES—Bit error secondsSES—Severely errored secondsSEFS—Severely errored framing secondsUAS—Unavailable secondsNames of the transmit queues and their associated statistics for each DS0 channel on the Channelized E1 to DS0 PIC.
BERT (bit error rate test) checks the quality of the line. This output appears only when a BERT is run on the interface.
Information about the configuration of the Packet Forwarding Engine:
Destination slot—FPC slot number.PLP byte—Packet Level Protocol byte.CoS transmit queue—Queue number and its associated user-configured forwarding class name.
bandwidth%—Percentage of bandwidth allocated to the queue.Bandwidth bps—Bandwidth allocated to the queue (in bps).buffer%—Percentage of buffer space allocated to the queue.Buffer usec—Amount of buffer space allocated to the queue, in microseconds. This value is nonzero only if the buffer size is configured in terms of time.Priority—Queue priority. Possible values arelowandhigh.Limit—Displayed if rate limiting is configured for the queue. Possible values arenoneandexact. Ifexactis configured,the queue transmits only up to the configured bandwidth, even if excess bandwidth is available. Ifnone is configured,the queue transmits beyond the configured bandwidth if bandwidth is available.Logical interface index number, which reflects its initialization sequence.
Unique number for use by Juniper Networks technical support only.
Information about the logical interface. Possible values are described in Logical Interface Flags.
Number and rate of bytes and packets received and transmitted on the logical interface.
(Frame Relay) Statistics for traffic received from and transmitted to the Routing Engine. When a burst of traffic is received, the value in the output packet rate field might briefly exceed the peak cell rate. It takes awhile (generally, less than 1 second) for this counter to stabilize.
(Frame Relay) Statistics for traffic transiting the router. When a burst of traffic is received, the value in the output packet rate field might briefly exceed the peak cell rate. It takes awhile (generally, less than 1 second) for this counter to stabilize.
Protocol family configured on the logical interface, such as
iso,inet6,mpls.(Multilink) Interface name for the multilink bundle, if configured.
Unique number for use by Juniper Networks technical support only.
Routing table in which the logical interface address is located. For example,
