Commands for Status Monitoring and Statistics

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 frames transmitted by the port that were lost.

• 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.
