Traffic statistics

Number and rate of bytes and packets received and transmitted on the physical interface.

  • Input bytes—Number of bytes received on the interface.
  • Output bytes—Number of bytes transmitted on the interface.
  • Input packets—Number of packets received on the interface
  • Output packets—Number of packets transmitted on the interface.

Note: The bandwidth bps counter is not enabled on the switch.

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 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).
  • 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 sanity checks of the headers. 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.
  • 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 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.
  • 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 switch interfaces.
  • MTU errors—Number of packets whose size exceeded the MTU of the interface.
  • Resource errors—Sum of transmit drops.

extensive

Egress queues

Total number of egress queues supported on the specified interface.

detail extensive

Queue counters (Egress )

CoS queue number and its associated user-configured forwarding class name.

  • Queued packets—Number of queued packets.
  • Transmitted packets—Number of transmitted packets.
  • Dropped packets—Number of packets dropped by the ASIC's RED mechanism.

detail extensive

Queue Number

The CoS queue number and the forwarding classes mapped to the queue number. The Mapped forwarding class column lists the forwarding classes mapped to each CoS queue.

detail 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 switch configuration, an alarm can ring the red or yellow alarm bell on the switch or turn on the red or yellow alarm LED on the front of the switch. 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

MAC statistics

Receive and Transmit statistics reported by the PIC's MAC subsystem.

  • Total octets and total packets—Total number of octets and packets. For Gigabit Ethernet IQ PICs, the received octets count varies by interface type.
  • 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 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—Number of packets that exceeds the configured MTU.
  • 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. This counter is not supported on EX Series switches and is always displayed as 0.
  • 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.

Autonegotiation information

Information about link autonegotiation:

  • Negotiation status:
    • Incomplete—Ethernet interface has the speed or link mode configured.
    • No autonegotiation—Remote Ethernet interface has the speed or link mode configured or does not perform autonegotiation.
    • Complete—Ethernet interface is connected to a device that performs autonegotiation and the autonegotiation process is successful.
  • Link partner status—OK when the Ethernet interface is connected to a device that performs autonegotiation and the autonegotiation process is successful.
  • Link partner:
    • Link mode—Depending on the capability of the attached Ethernet device, either Full-duplex or Half-duplex.
    • Flow control—Types of flow control supported by the remote Ethernet device. For Gigabit Ethernet interfaces, types are Symmetric (link partner supports PAUSE on receive and transmit), Asymmetric (link partner supports PAUSE on transmit), and Symmetric/Asymmetric (link partner supports PAUSE on both receive and transmit or PAUSE only on receive).
    • Remote fault—Remote fault information from the link partner—Failure indicates a receive link error. OK indicates that the link partner is receiving. Negotiation error indicates a negotiation error. Offline indicates that the link partner is going offline.
    • Link partner speed—Speed of the link partner.
  • Local resolution:
    • Flow control—Types of flow control supported by the remote Ethernet device. For Gigabit Ethernet interfaces, types are Symmetric (link partner supports PAUSE on receive and transmit), Asymmetric (link partner supports PAUSE on transmit), and Symmetric/Asymmetric (link partner supports PAUSE on both receive and transmit or PAUSE only on receive).

      For asymmetric PAUSE, shows if the PAUSE transmit and PAUSE receive states on the interface are enable or disable.

    • Remote fault—Remote fault information. Link OK (no error detected on receive), Offline (local interface is offline), and Link Failure (link error detected on receive).
