of unwanted signals that can disrupt communication between other devices on the network. This is especially common what is a jabber id on Ethernet networks, in which each device must compete for use of the line using the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) contention protocol. When a NIC jabbers what is a jabber account on an Ethernet network, all network communication might cease until the offending NIC is replaced. Other causes of jabbering on a network include a faulty NIC, loose cabling, or a poorly grounded cable (for shielded cabling). The term “jabber” is also used in the Institute of Electrical and Electronic Engineers (IEEE) 802.3 specification for any frame of data that

exceeds the maximum frame length for that specification. For Ethernet networks, the maximum frame length is 1518 bytes (18 bytes of overhead and 1500 bytes of payload). A frame longer than 1518 bytes is often called a “jabber frame.” Another name for jabbering is “long packet error.” Jabbering can also occur in Fast Ethernet networks, in which a combination of 100BaseT4 and 100BaseTX cabling schemes are employed in one network. The continuously generated idle stream signal of the TX network can appear to the T4 network as jabber and can bring down the entire network. This should not be a problem if all network devices implement autonegotiation in an IEEE-compliant fashion. In addition, Fast Ethernet repeaters generally implement jabber control by automatically disconnecting any port that transmits information in streams longer than 40 Kb. NOTE A frame shorter than 64 bytes on an Ethernet network is called a “runt frame.” Featured DHCP Maintenance Guide RAID RAID 0 RAID 1 RAID 5 Migrating Apache to IIS Migrating with the IIS Tool Migrating web sites m

The switch port is set to Autonegotiate both the speed and duplex and it negotiates to 100Mbps/Full Duplex when the cuda connects. I've verified that the cable is just fine too.Anyone else seeing similar error on their switches?

If one end is auto - then both ends must be auto or 99 times out of 100 one side runs half duplex and the other side runs full duplex with exactly the errors you describe!
