show controllers ethernet-controller
show controllers ethernet-controller
Use the show controllers ethernet-controller privileged EXEC command without keywords to display
per-interface send and receive statistics read from the hardware. Use with keywords to display the
interface internal registers.
show controllers ethernet-controller interface-id [asic | phy] [ | {begin | exclude | include}
expression]
Syntax Description
Command Modes Privileged EXEC (only supported with the interface-id keywords in user EXEC mode)
Command History
Usage Guidelines This display without keywords provides traffic statistics, basically the RMON statistics for the interface.
When you enter the asic or phy keyword, the displayed information is useful primarily for Cisco
technical support representatives troubleshooting the switch.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output
do not appear, but the lines that contain Output appear.
Examples This is an example of output from the show controllers ethernet-controller command. Table 2-15
