P
ORT
The Summit keeps track of errors for each port.
To view port error, enter
show port <portlist> errors
The following port error information is collected by the Switch:
¥ Link Status Ñ The current status of the link. Options are
Ñ Ready Ñ The port is ready to accept a link.
Ñ Active Ñ The link is present at this port.
¥ Transmit Collisions (TX Coll) Ñ The total number of collisions seen by the port,
regardless of whether a device connected to the port participated in any of the
collisions.
¥ Transmit Late Collisions (TX Late) Ñ The total number of collisions that have
occurred after the portÕs transmit window has expired.
¥ Transmit Deferred Frames (TX Def) Ñ The total number of frames that were
transmitted by the port after the Þrst transmission attempt was deferred by other
network trafÞc.
¥ Transmit Frames Lost (TX Lost) Ñ The total number of frames that were not
completely transmitted by the port because of underßow.
¥ Transmit Errored Frames (TX Err) Ñ The total number of frames that were not
completely transmitted by the port because of network errors (such as late collisions
or excessive collisions).
¥ Receive Bad CRC Frames (RX CRC) Ñ The total number of frames received by the
port that were of the correct length, but contained a bad FCS value.
¥ Receive Oversize Frames (RX Over) Ñ The total number of good frames received
by the port that were of greater than the supported maximum length of 1,522 bytes.
¥ Receive Undersize Frames (RX Under) Ñ The total number of frames received by
the port that were less than 64 bytes long.
¥ Receive Jabber Frames (RX Jab) Ñ The total number of frames received by the port
that was of greater than the support maximum length and had a Cyclic Redundancy
Check (CRC) error.
¥ Receive Alignment Errors (RX Align) Ñ The total number of frames received by the
port that occurs if a frame has a CRC error and does not contain an integral number
of octets.
