Release Information

Command introduced in Junos OS Release 9.0 for EX Series switches.

Description

Display status information about the specified 10-Gigabit Ethernet interface.

Note: You must have a transceiver plugged into an SFP+ or an XFP port before information about the interface can be displayed.

Note: On an EX Series switch, the traffic statistics for a LAG might vary slightly from the cumulative traffic statistics of the member interfaces of the LAG. This difference is more likely to be seen when the traffic is bursty in nature, and because the statistics are not fetched from the LAG and the members in the same instant. For accurate traffic statistics for a LAG, use the aggregated Ethernet counters.

Options

xe-fpc/pic/port

—

Display standard information about the specified 10-Gigabit Ethernet interface.

brief | detail | extensive | terse

—

(Optional) Display the specified level of output.

media

—

(Optional) Display media-specific information about network interfaces. For 10-Gigabit Ethernet interfaces, using the media option does not provide you with new or additional information. The output is the same as when the media option is not used.

statistics

—

(Optional) Display static interface statistics. For 10-Gigabit Ethernet interfaces, using the statistics option does not provide you with new or additional information. The output is the same as when the statistics option is not used.

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 and rate in bits per second. Output bytes—Number of bytes transmitted on the interface and rate in bits per second. Input packets—Number of packets received on the interface and rate in packets per second. Output packets—Number of packets transmitted on the interface and rate in packets per second.	detail extensive
IPv6 transit statistics	EX Series switches do not support the collection and reporting of IPv6 transit statistics.	detail extensive
Input errors	Input errors on the interface: 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 the Junos OS does not handle. L3 incompletes—Number of incoming packets discarded because they failed Layer 3 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 if you configure 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: 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. A 10-Gigabit Ethernet interface supports only full-duplex operation, so for 10-Gigabit Ethernet interfaces, 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
Ingress queues	Number of CoS ingress queues supported on the specified interface. Displayed only for an interface on a line card with oversubscribed ports.	detail extensive
Egress queues	Number of CoS egress queues supported on the specified interface.	detail extensive
PFE Egress queues	Number of Packet Forwarding Engine egress queues shared by the interfaces in a port group. Displayed only for an interface on a line card with oversubscribed ports.	detail extensive
Queue counters	Statistics for queues: Queued packets—Number of queued packets. This counter is not supported on EX switches and always contains 0. Transmitted packets—Number of transmitted packets. Dropped packets—Number of packets dropped by the ASIC's RED mechanism.	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. 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 frames that exceed 1518 octets. 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. Code violations—Number of times an event caused the PHY to indicate “Data reception error” or “invalid data symbol error.”	extensive
Packet Forwarding Engine configuration	Information about the configuration of the Packet Forwarding Engine: Destination slot—FPC slot number: On standalone switches with built-in interfaces, the slot number refers to the switch itself and is always 0. On Virtual Chassis composed of switches with built-in interfaces, the slot number refers to the member ID of the switch. On switches with line cards or on Virtual Chassis composed of switches with line cards, the slot number refers to the line card slot number on the switch or Virtual Chassis.	extensive
CoS Information	Scheduler information for the CoS egress queues on the physical interface: Direction—Queue direction, always Output. CoS transmit queue—Queue number and its associated user-configured forwarding class name. Bandwidth—Information about bandwidth allocated to the queue: %—Bandwidth allocated to the queue as a percentage bps—Bandwidth allocated to the queue in bps Buffer—Information about buffer space allocated to the queue: %—Buffer space allocated to the queue as a percentage. usec—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: low or high. Limit—Displayed if rate limiting is configured for the queue. Possible values are none and exact. If exact is configured, the queue transmits only up to the configured bandwidth, even if excess bandwidth is available. If none is configured, the queue transmits beyond the configured bandwidth if bandwidth is available.	extensive
