Port Error Statistics
Description
Select port: Selects the range of ports to view. You can view statistics for
four ports at a time. Press
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.
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 that exceed the maximum
allowed frame size but are otherwise valid Ethernet frames (good CRC).
allowed frame size but are otherwise valid Ethernet frames (good CRC).
Fragments: Displays the number of frames that are less than 64 bytes,
including frames without a start-of-frame delimiter. A fragmented frame
also has an invalid CRC.

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.
