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 this command with keywords to
display the interface internal registers or to display the statistics read from Long-Reach Ethernet (LRE)
and customer premises equipment (CPE) ports.

exclude | include} expression]
Syntax Description
Command Modes Privileged EXEC (only supported with the interface-id keywords in user EXEC mode)
Command History
Usage Guidelines Use this command without keywords to display traffic statistics, particularly the RMON statistics for the
interface. If this command is entered on a Catalyst 2950 LRE switch, the command output also shows
the statistics for the LRE switch interfaces.
When you enter the asic or phy 32 keyword, the displayed information is primarily useful for Cisco
technical support representatives troubleshooting the switch. When you enter the cpe keyword, the
displayed information shows the traffic statistics for the connected CPE devices. The CPE Ethernet link
on an LRE switch port is the connection between the Cisco LRE CPE and the remote Ethernet device
(such as a PC) connected to it. It is not the link between the LRE switch port and the LRE CPE device.
interface-id ID of the switch interface.
asic (Optional) Display the state of the internal registers on the forwarding
application-specific integrated circuit (ASIC) for the interface. This keyword is
available only on non-LRE switches.
cpe [port port-id] (Optional) Display statistics from the LRE and Fast Ethernet ports on connected
devices.
• port port-id—Display the Ethernet statistics of the designated CPE Ethernet
port. The range is 1 to 4, depending on the CPE device.
These keywords are available only on LRE switches.
phy 32 (Optional) Display the status of the internal registers on the switch physical layer
device (PHY) for the interface. This keyword is available only on non-LRE
switches.
| begin (Optional) Display begins with the line that matches the expression.
| exclude (Optional) Display excludes lines that match the expression.
| include (Optional) Display includes lines that match the specified expression.
expression Expression in the output to use as a reference point.
