How do I approach my boss to discuss this? You have exceeded the maximum character limit. Today, the term Ethernet is often used to refer to all carrier sense multiple access collision detect (CSMA/CD) LANs that generally conform to Ethernet specifications, including IEEE 802.3. This field specifies the upper-layer protocol to receive the data after Ethernet processing is complete. my review here
Use a protocol analyzer to try to determine the source address of the runt frames. output hang Gives the number of hours, minutes, and seconds (or never) since the interface was last reset because of a transmission that took too long. An extension of NLPs is fast link pulses. If the network interfaces supported different speeds or different modes of operation, they will attempt to settle on a lower common denominator. visit
Another name for this shared LAN is a collision domain. Three new takes on WAN optimization Once considered new technology, WAN optimization is now widespread, and enterprises are including it in their networks from the ... Nodes that transmit Ethernet frames append an FCS number, which lets the receiving device determine if the packet is complete and correct upon arrival. packets output Shows the total number of messages transmitted by the system.
This issue might also be the cause of some of my CRC errors possibly...»Shielding for CAT5 LAN cables... Cisco Interface Crc Error The source address is always a unicast (single node) address, whereas the destination address may be unicast, multicast (group), or broadcast (all nodes). Ethernet is most similar to IEEE 802.3 10Base5. http://networkengineering.stackexchange.com/questions/1467/what-is-the-meaning-of-the-crc-counter-on-a-cisco-device Is it legal for Callwithus to deactivate accounts after 3 months [VOIPTechChat] by bekfe10© DSLReports · Est.1999feedback · terms · Mobile mode

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

The first 3 bytes of the addresses are specified by the IEEE on a vendor-dependent basis, and the last 3 bytes are specified by the Ethernet or IEEE 802.3 vendor. http://ebprovider.com/crc-error/crc-error-cisco-router.php Maybe add possible causes to your post like duplex mismatch and faulty cabling. –Daniel Dib May 31 '13 at 9:08 @ytti thank you for the tip concerning the book SearchMobileComputing Windows 10 piques IT interest in 2-in-1 devices Organizations that want to offer employees portability and PC functionality are turning toward 2-in-1 devices.

Alignment errors should always generate FCS errors.

If the interface is not in promiscuous mode, it senses network traffic it sends and receives (rather than all network traffic). If a signal is detected (carrier sense), then stations should not attempt to transmit frame. Five minute input rate, Five minute output rate Gives the average number of bits and packets transmitted per second in the past 5 minutes. useful reference You can withdraw your consent at any time.
