Extended port information

Satellite device port ID

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.

IPv6 transit 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.

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.

• Giants—Number of frames received that are greater than the giant 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.

• Resource errors—Sum of transmit drops.

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.

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

• Resource errors—Sum of transmit drops.

Egress queues

Total number of egress queues supported on the specified interface.

Queue counters

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.

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.

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 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.

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.

Packet Forwarding Engine configuration

Information about the configuration of the Packet Forwarding Engine:

• Destination slot—FPC slot number.

• 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: 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.
