Table 4: show interfaces Gigabit Ethernet Output Fields (continued)

Level of OutputField DescriptionField Name

extensiveReceive 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 (10-Gigabit

Ethernet) 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.”
