However if the connected device is designed to work with full duplex then yes it could cause a problem but that would be something you would have to ask the manufacture. Frames that are too short (under 64 bytes, called runts), or too long (more than 1,518 bytes without a signal that a long frame is coming) or giant (more than 6,000 up vote 9 down vote favorite 4 I'm seeing network problems with a (RHEL) node (packets dropped), which also seem to manifest themselves by a non-zero count of the 'error' and here

  1. we had two occasions where the switch decided to dynamically change speed and all the AMX devices scattered around the building needed to be rebooted.
  2. The disadvantage is that data frames with FCS errors may be propagated to the next hop because transmission out of the switch begins before the FCS error is detected.
  3. Is the set cover problem NP-complete when the cardinality of the collection of sets is equal to the cardinality of the universe?
  4. average only 30KB/s.
  5. As with other FCS errors, alignment errors most often result from noise on the cabling, although hardware problems in network interface cards or other network hardware can also cause them.
