ExtremeWare XOS 11.0 Command Reference Guide 387
show ports txerrors
show ports {<port_list>} txerrors
Description
Displays real-time transmit error statistics.
Syntax Description
Default
N/A.
Usage Guidelines
If you do not specify a port number or range of ports, error statistics are displayed for all ports.
This status information may be useful for your technical support representative if you have a network
problem.
The switch collects the following port transmit error information:
• Port Number
• Link Status—The current status of the link. Options are:
— Ready (R): The port is ready to accept a link.
— Active (A): The link is present at this port.
• Transmit Collisions (TX Coll)—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 Coll)—The total number of collisions that have occurred after the
port’s transmit window has expired.
• Transmit Deferred Frames (TX Deferred)—The total number of frames that were transmitted by the
port after the first transmission attempt was deferred by other network traffic.
• Transmit Errored Frames (TX Error)—The total number of frames that were not completely
transmitted by the port because of network errors (such as late collisions or excessive collisions).
• Transmit Lost Frames (TX Lost)—The total number of transmit frames that do not get completely
transmitted because of buffer problems (FIFO underflow).
• Transmit Parity Frames (TX Parity)—The bit summation has a parity mismatch.
Example
The following command displays transmit error statistics for slot 5, ports 4 through 7 on a modular
switch:
show ports 5:4-5:7 txerrors
port_list Specifies one or more slots and ports. May be in the form 2:*, 2:5, 2:6-2:8.
