Syntax Description

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.
For PoS modules, displays the
txerror
information for the PoS ports. Only a subset of the statistics
displayed by this command is applicable to PoS ports. The fields that do not apply to PoS ports are
displayed with values of all zeroes.
The following port transmit error information is collected by the switch:
• 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.
— Disabled (D): The link is disabled at this port.
— Not Present (NP): The link is not 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.
mgmt Specifies the management port.
NOTE: This option is available only on switches that provide a management port.
portlist Specifies one or more ports or slots and ports. On a modular switch, can be a list of slots and ports.
On a stand-alone switch, can be one or more port numbers. May be in the form 1, 2, 3-5, 2:5, 2:6-2:8.
vlan Denotes the VLAN name for which the statistics are presented. For example, if VLAN name “v1” has
ports x, y, and z, the command
show port vlan v1 txerrors
displays the txerror statistics for
ports x, y, and z.
