Chapter 56: Operational Mode Commands for Interfaces Table 139: show interfaces xe- Output Fields (continued) Field Name Field Description Level of Output Queue counters (Packet Forwarding Engine Egress) Statistics for the Packet Forwarding Engine egress queues: detail extensive • Queued packets-Number of queued packets. • Transmitted packets-Number of transmitted packets. • Dropped packets-Number of packets dropped by the ASIC's RED mechanism. Displayed for an interface on a 40-port SFP+ line card. 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. detail extensive none • 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. PCS statistics Physical Coding Sublayer (PCS) fault conditions from the LAN PHY device. detail extensive MAC statistics Receive and Transmit statistics reported by the PIC's MAC subsystem. extensive • 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 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." 1023
