If 100BaseTX is being used, ensure Category 5 cabling is being used and not another type, such as Category 3. There have been 1599 'frame errors' reported. This indicates the number In the case of IEEE 802.3, the upper-layer protocol must be defined within the data portion of the frame, if at all.

Troubleshooting Ethernet Table4-5 provides troubleshooting procedures for common Ethernet media problems.
Addresses are contained in hardware on the Ethernet and IEEE 802.3 interface cards. Ethernet is well suited to applications on which a local communication medium must carry sporadic, occasionally heavy traffic at high peak data rates. port-adapter--Refer to the appropriate hardware manual for information about port adapter compatibility. Ethernet frame CRC (FCS) is usually understood to be on OSI layer 2, many people claim it is layer 1 on Ethernet, but that is incorrect (only preamble, SFD and IFG
In Ethernet frames, the 2-byte field following the source address is a type field. When you're troubleshooting Ethernet media in a Cisco router environment, the show interfaces ethernet command provides several key fields of information that can assist with isolating problems. All network devices can discard packets, and are expected to. Frame Errors FCS ErrorsFrame Check Sequence (FCS) Errors, a type of CRC, indicate that frames received by an interface are an integral number of octets long but do not pass the FCS check.

Too Short Errors (Runt)A Too Short Error, also called a runt, indicates that a packet is fewer than 64 octets long (including FCS octets) but otherwise well formed.10. Cisco Crc Errors Fiber Late collisions should never occur in a properly designed Ethernet network. Output queue, input queue, drops Gives the number of packets in output and input queues.

Other input-related errors can also cause the input error count to be increased, and some datagrams may have more than one error; therefore, this sum may not balance with the sum
The type field and the LLC header are not replacements for each other, but they serve to offer backward compatibility between network protocol implementations without rewriting the entire Ethernet frame. Input Errors And Crc Errors On Serial Interface Too Long Errors (Giants/Jumbo)A Too Long Error indicates that a packet is longer than 1518 octets (including FCS octets) but otherwise well formed. This field specifies the upper-layer protocol to receive the data after Ethernet processing is complete.

If a station "hears" another signal on the wire while transmitting the first 64 bytes of a frame, it should recognize that its frame has collided with another. 2. If it is a destination, the frame is passed to a higher protocol layer for appropriate processing.
