Port Error Statistics
Description
Select Port: Selects the range of ports to view. Statistics are displayed four
ports at a time. Press z to toggle between port numbers. The
example shows ports 1-4.
Update Interval: Selects the time period between updates (press
z). 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 Error: Displays the number of valid length frames (between 64 and
1536 bytes) that had a bad Frame Check Sequence (FCS).
Oversize Frames: Displays the number of frames exceeding the maximum
allowed frame size but are otherwise valid Ethernet frames (good CRC).
Fragments: Displays 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.
