Port Error Statistics
Description
Select Port: Selects the range of ports to view. Statistics are displayed four
ports at a time. Press the z to toggle between port numbers and the
optional module. The example shows ports 1-4 on a 24-port switch.
Update interval: Press the z to select the time period between
updates. For example, an Update interval of 5 sec means Local
Management collects and displays information from the switch every five
seconds.
Speed/Duplex: Displays the current connection status of the port.
CRC Errors: This statistic counts the number of valid length frames
(between 64 and 1536 bytes) that had a bad Frame Check Sequence (FCS).
Oversize Frames: Number of frames exceeding the maximum allowed
frame size but are otherwise valid Ethernet frames (good CRC).
Fragment: The number of frames that are less than 64 bytes; this number
includes frames without a start-of-frame delimiter. A fragmented frame
also has an invalid CRC.
Jabber: Indicates that a device (such as a faulty NIC) on the network is
sending improper electrical signals. Because Ethernet uses electrical
signaling to determine whether it can transmit, a jabber condition can halt
all traffic on a segment.
