Runts |
Runts are ethernet Frames that are less than 64 bytes |
|
|
Giants |
Ethernet frames that exceed the IEEE 802.3 frame size (1518 bytes, no Jumbo frames) and have a incorrect FCS (Frame Check Sequence) |
|
|
Input errors |
Thiscounter will increase when the interface receives a frame with any kind oferror, this includes runts, giants, no buffer available, CRC errors, etc. |
|
|
CRC |
Thenumber of packets received with CRC (Cyclic Redundancy Checksum) errors. Thismeans that the checksum that was generated by the sender does not match thechecksum that the receiver calculated. On a LAN this typically occurs when youhave issues with cabling or defective network cards. |
|
|
Frame |
Thenumber of packets that were received with a CRC error and a nonintegernumber of octets |
|
|
Source port and destination port |
Identifythe points (sockets) at which upper-layer source and destination processesreceive TCP services. |
|
|
Sequence number |
Usuallyspecifies the number assigned to the first byte of data in the current message.Under certain circumstances, it can also be used to identify an initialsequence number to be used in the upcoming transmission. |
|
|
Acknowledgment number |
containsthe sequence number of the next byte of data that the sender of the packetexpects to receive. |
|
|
Data offset |
Indicatesthe number of 32-bit words in the TCP header. |
|
|
Reserved |
Reserved for future use |
|
|
Flags |
carries a variety of control information |
|
|
Window |
Specifies the size of the sender's receive window (buffer space available for incoming data). |
|
|
Checksum |
Provides information used to determine whether the header was damaged in transit |
|
|
Urgent pointer |
Points to the first urgent data byte in the packet |
|
|
Options |
Specifies various TCP options |
|
|
DATA |
contains upper-layer information |
