• Output bytes—Number of bytes transmitted on the interface. The value in this field also includes the Layer 2 overhead bytes for egress traffic on Ethernet interfaces if you enable accounting of Layer 2 overhead at the PIC level or the logical interface level.

• Input packets—Number of packets received on the interface.

• Output packets—Number of packets transmitted on the interface.

Gigabit Ethernet and 10-Gigabit Ethernet IQ PICs count the overhead and CRC bytes.

For Gigabit Ethernet IQ PICs, the input byte counts vary by interface type. For more information, see Table 31 under the show interfaces command.

detail extensive

Input errors

Input errors on the interface. The following paragraphs explain the counters whose meaning might not be obvious:

• Errors—Sum of the incoming frame terminates 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).

• 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 Junos OS 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. L3 incomplete errors can be ignored by configuring the ignore-l3-incompletes statement.

• 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.

• FIFO errors—Number of FIFO errors in the receive direction that are reported by the ASIC on the PIC. If this value is ever nonzero, the PIC is probably malfunctioning.

• Resource errors—Sum of transmit drops.

extensive

Output errors

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 from down to up. This number does not normally increment quickly, increasing only when the cable is unplugged, the far-end system is powered down and then up, or another problem occurs. If the number of carrier transitions increments quickly (perhaps once every 10 seconds), the cable, the far-end system, or the PIC or PIM is malfunctioning.

• Errors—Sum of the outgoing frame terminates 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.

  Note:

  Due to accounting space limitations on certain Type 3 FPCs (which are supported in M320 and T640 routers), the Drops field does not always use the correct value for queue 6 or queue 7 for interfaces on 10-port 1-Gigabit Ethernet PICs.

• Collisions—Number of Ethernet collisions. The Gigabit Ethernet PIC supports only full-duplex operation, so for Gigabit Ethernet PICs, this number should always remain 0. If it is nonzero, there is a software bug.

• 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.

• FIFO errors—Number of FIFO errors in the send direction as reported by the ASIC on the PIC. If this value is ever nonzero, the PIC is probably malfunctioning.

• HS link CRC errors—Number of errors on the high-speed links between the ASICs responsible for handling the router interfaces.

• MTU errors—Number of packets whose size exceeded the MTU of the interface.

• Resource errors—Sum of transmit drops.

• Dropped packets—Number of packets dropped by the ASIC's RED mechanism.

  Note:

  Due to accounting space limitations on certain Type 3 FPCs (which are supported in M320 and T640 routers), the Dropped packets field does not always display the correct value for queue 6 or queue 7 for interfaces on 10-port 1-Gigabit Ethernet PICs.

Ingress queues

Total number of ingress queues supported on the specified interface. Displayed on IQ2 interfaces.

extensive

Queue counters (Ingress)

CoS queue number and its associated user-configured forwarding class name. Displayed on IQ2 interfaces.

• Queued packets—Number of queued packets.

• Transmitted packets—Number of transmitted packets.

• Dropped packets—Number of packets dropped by the ASIC's RED mechanism.

extensive

Active alarms and Active defects

Ethernet-specific defects that can prevent the interface from passing 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. These fields can contain the value None or Link.

• None—There are no active defects or alarms.

• Link—Interface has lost its link state, which usually means that the cable is unplugged, the far-end system has been turned off, or the PIC is malfunctioning.

detail extensive none

Interface transmit statistics

(On MX Series devices) Status of the interface-transmit-statistics configuration: Enabled or Disabled.

• Enabled—When the interface-transmit-statistics statement is included in the configuration. If this is configured, the interface statistics show the actual transmitted load on the interface.

• Disabled—When the interface-transmit-statistics statement is not included in the configuration. If this is not configured, the interface statistics show the offered load on the interface.

detail extensive

OTN FEC statistics

The forward error correction (FEC) counters provide the following statistics:

• Corrected Errors—The count of corrected errors in the last second.

• Corrected Error Ratio—The corrected error ratio in the last 25 seconds. For example, 1e-7 is 1 error per 10 million bits.

detail extensive

PCS statistics

(10-Gigabit Ethernet interfaces) Displays Physical Coding Sublayer (PCS) fault conditions from the WAN PHY or the LAN PHY device.

• Bit errors—The number of seconds during which at least one bit error rate (BER) occurred while the PCS receiver is operating in normal mode.

• Errored blocks—The number of seconds when at least one errored block occurred while the PCS receiver is operating in normal mode.

detail extensive

MAC statistics

Receive and Transmit statistics reported by the PIC's MAC subsystem, including the following:

• Total octets and total packets—Total number of octets and packets. For Gigabit Ethernet IQ PICs, the received octets count varies by interface type. For more information, see Table 31 under the show interfaces command.

• Unicast packets, Broadcast packets, and Multicast packets—Number of unicast, broadcast, and multicast packets.

• CRC/Align errors—Total number of packets received that had a length (excluding framing bits, but including FCS octets) of between 64 and 1518 octets, inclusive, and had either a bad FCS with an integral number of octets (FCS Error) or a bad FCS with a nonintegral number of octets (Alignment Error).

• FIFO error—Number of FIFO errors that are reported by the ASIC on the PIC. If this value is ever nonzero, the PIC or a cable is probably malfunctioning.

• MAC control frames—Number of MAC control frames.

• MAC pause frames—Number of MAC control frames with pause operational code.

• Oversized frames—There are two possible conditions regarding the number of oversized frames:

  • Packet length exceeds 1518 octets, or

  • Packet length exceeds MRU

• Jabber frames—Number of frames that were longer than 1518 octets (excluding framing bits, but including FCS octets), and had either an FCS error or an alignment error. This definition of jabber is different from the definition in IEEE-802.3 section 8.2.1.5 (10BASE5) and section 10.3.1.4 (10BASE2). These documents define jabber as the condition in which any packet exceeds 20 ms. The allowed range to detect jabber is from 20 ms to 150 ms.

• Fragment frames—Total number of packets that were less than 64 octets in length (excluding framing bits, but including FCS octets) and had either an FCS error or an alignment error. Fragment frames normally increment because both runts (which are normal occurrences caused by collisions) and noise hits are counted.

• VLAN tagged frames—Number of frames that are VLAN tagged. The system uses the TPID of 0x8100 in the frame to determine whether a frame is tagged or not.

  Note:

  The 20-port Gigabit Ethernet MIC (MIC-3D-20GE-SFP) does not have hardware counters for VLAN frames. Therefore, the VLAN tagged frames field displays 0 when the show interfaces command is executed on a 20-port Gigabit Ethernet MIC. In other words, the number of VLAN tagged frames cannot be determined for the 20-port Gigabit Ethernet MIC.

• Code violations—Number of times an event caused the PHY to indicate “Data reception error” or “invalid data symbol error.”

Filter statistics

Receive and Transmit statistics reported by the PIC's MAC address filter subsystem. The filtering is done by the content-addressable memory (CAM) on the PIC. The filter examines a packet's source and destination MAC addresses to determine whether the packet should enter the system or be rejected.

• Input packet count—Number of packets received from the MAC hardware that the filter processed.

• Input packet rejects—Number of packets that the filter rejected because of either the source MAC address or the destination MAC address.

• Input DA rejects—Number of packets that the filter rejected because the destination MAC address of the packet is not on the accept list. It is normal for this value to increment. When it increments very quickly and no traffic is entering the router from the far-end system, either there is a bad ARP entry on the far-end system, or multicast routing is not on and the far-end system is sending many multicast packets to the local router (which the router is rejecting).

• Input SA rejects—Number of packets that the filter rejected because the source MAC address of the packet is not on the accept list. The value in this field should increment only if source MAC address filtering has been enabled. If filtering is enabled, if the value increments quickly, and if the system is not receiving traffic that it should from the far-end system, it means that the user-configured source MAC addresses for this interface are incorrect.

• Output packet count—Number of packets that the filter has given to the MAC hardware.

• Output packet pad count—Number of packets the filter padded to the minimum Ethernet size (60 bytes) before giving the packet to the MAC hardware. Usually, padding is done only on small ARP packets, but some very small IP packets can also require padding. If this value increments rapidly, either the system is trying to find an ARP entry for a far-end system that does not exist or it is misconfigured.

• Output packet error count—Number of packets with an indicated error that the filter was given to transmit. These packets are usually aged packets or are the result of a bandwidth problem on the FPC hardware. On a normal system, the value of this field should not increment.

• CAM destination filters, CAM source filters—Number of entries in the CAM dedicated to destination and source MAC address filters. There can only be up to 64 source entries. If source filtering is disabled, which is the default, the values for these fields should be 0.

Received path trace, Transmitted path trace

(10-Gigabit Ethernet interfaces, WAN PHY mode) SONET/SDH interfaces allow path trace bytes to be sent inband across the SONET/SDH link. Juniper Networks and other router manufacturers use these bytes to help diagnose misconfigurations and network errors by setting the transmitted path trace message so that it contains the system hostname and name of the physical interface. The received path trace value is the message received from the router at the other end of the fiber. The transmitted path trace value is the message that this router transmits.
