When you are troubleshooting duplex mismatches, which two errors are typically seen on the full- duplex end? (Choose two.)
A. runts
B. FCS errors
C. interface resets
D. late collisions
Full-duplex endでは、runtsとFCS errorが表示される。
Runts is an error which means “packet too small”.In ethernet, the packet has to have more than 64 bytes long.
FCS Error is a check mechanism of whole frame. The packet source calculate the checksum in whole single frame when it transmit the packet. Then the source adds the result of checksum calculation and transmit the frame.
The destination calculate the checksum in whole single frame when it receives the packet, with the same way as the packet source did. So that means the checksum result would be the same value.
If the checksums are different between source and receiver, the destination discards the frame and ask the source to retransmit the frame.
Runts and FCS error occur in the situation of fragments or collisions. They could be seen in Full-Duplex end.
