setup express
Use the setup express global configuration command to enable Express Setup mode on the switch. This is the default setting. Use the no form of this command to disable Express Setup mode.
setup express
no setup express
Syntax Description
This command has no arguments or keywords.
Defaults
Express Setup is enabled.
Command Modes
Global configuration
Command History
Usage Guidelines
When Express Setup is enabled on a new (unconfigured) switch, pressing the Mode button for 2 seconds activates Express Setup. You can access the switch through an Ethernet port by using the IP address 10.0.0.1 and then can configure the switch with the web-based Express Setup program or the command-line interface (CLI)-based setup program.
When you press the Mode button for 2 seconds on a configured switch, the mode LEDs start flashing. If you press the Mode button for a total of 10 seconds, the switch configuration is deleted, and the switch reboots. The switch can then be configured like a new switch, either through the web-based Express Setup program or the CLI-based setup program.
Note
If Express Setup is active on the switch, entering the write memory or copy running-configuration startup-configuration privileged EXEC commands deactivates Express Setup. The IP address 10.0.0.1 is no longer valid on the switch, and your connection using this IP address ends.
The primary purpose of the no setup express command is to prevent someone from deleting the switch configuration by pressing the Mode button for 10 seconds.
Examples
This example shows how to enable Express Setup mode:
Switch(config)# setup expressYou can verify that Express Setup mode is enabled by pressing the Mode button:
•
•
Caution
This example shows how to disable Express Setup mode:
Switch(config)# no setup expressYou can verify that Express Setup mode is disabled by pressing the Mode button. The mode LEDs only turn solid green or begin flashing green if Express Setup mode is enabled on the switch.
Related Commands
Exits Express Setup mode without saving the configuration.
Displays if Express Setup mode is active on the switch.

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.
show controllers ethernet-controller interface-id [asic | cpe [port port-id] | phy] [ | {begin | exclude | include} expression]
Syntax Description
Command Modes
Privileged EXEC
Command History
12.1(6)EA2
This command was introduced.
12.1(11)YJ
The cpe and port port-id keywords were added.
Usage Guidelines
Use this command without keywords to display traffic statistics, basically 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 keyword, the displayed information is useful primarily 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.
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 on a non-LRE switch. For this example, Table 2-9 describes the Transmit fields, Table 2-10 describes the Receive fields, and Table 2-11 describes the Transmit and Receive fields.

show controllers lre actual
Use the show controllers lre actual privileged EXEC command to display the actual values of the Long-Reach Ethernet (LRE) link on a specific LRE switch port.
show controllers lre interface-id actual {dsrserrs | link | rxpower | snr | txpower | usrserrs}
[ | {begin | exclude | include} expression]This command is available only on Catalyst 2950 LRE switches.
Syntax Description
Command Modes
Privileged EXEC
Command History
Usage Guidelines
You can use the SNR and Reed-Solomon error information to measure the quality of the LRE link. The SNR is the amount of increased received signal-power (in decibels) relative to the noise-power level that the switch can tolerate without disconnecting from the CPE device. The higher the ratio, the more resilient is the link.
The Reed-Solomon errors show the number of errors detected and corrected in the data being received on and sent from the switch LRE ports. Reed-Solomon errors are the result of noise exceeding the noise margin. For short bursts of noise (such as motor power on or power surges), the interleave feature prevents the loss of Ethernet data packets. Then the number of Reed-Solomon errors exceeds the number of Ethernet CRC errors.
The remote transmit power-rates from the connected CPE devices might be different from each other, depending on how long the cable is between the switch and the CPE device. A longer cable typically causes the CPE device to send a higher signal to overcome the loss effects of distance.
The local receive-power actually displays the switch's adjustment to the incoming power level. These numbers might be different from LRE port to LRE port, as the length of the cables to the CPE devices might be different.
If the SNR is too low for the environment but the link still establishes, the Reed-Solomon error rate is high, and there might be link instability (as shown by the number of Fail events counted). If the network is being used for data only, a high incidence of Ethernet Frame Check Sequence (FCS) errors or micro-interruptions might be tolerable.
For more information about what can affect the LRE link and for the minimum required SNR ratios, refer to the "LRE Links and LRE Profiles" section in the "Configuring LRE" chapter of the switch software configuration guide for this release.

Syntax Description
Command Modes
Privileged EXEC
Command History
Usage Guidelines
The link monitor process collects errror information at minute intervals for 15 minutes. After 15 minutes, the data is analyzed and stored before starting a new collection sequence. Up to 2 hours of link monitor data can be shown.
Local monitoring collects data from the LRE switch. Remote monitoring collects data from attached CPE device.
The Time heading in the show controllers lre link monitor errors command output shows the timestamp for the last collection sequence. The RS error count shows the cumulative error count from the last reading. Alignment errors, frame check sequence (FCS) errors, receive errors, and oversize errors are the Ethernet statistics collected either at the switch or at the CPE device.
The Time heading in the show controllers lre link monitor parameters command output shows the timestamp for the last collection sequence. The signal-to-noise (SNR) error counter, shown under the SNR Err heading, increments when the SNR value read from the chipset falls below the theoretical SNR added to the threshold.
The Time heading in the show controllers lre link monitor statistics command output shows the timestamp for the last collection sequence. The RS error count shows the cumulative error count from the last reading. This count is cleared only when the interface is shut down or when the clear controllers lre link monitor privileged EXEC command is entered. The RS error alarm shows the number of 1 minute intervals that had RS errors above the configured threshold.
Use the show controllers lre monitor {errors | parameters | statistics} privileged EXEC command without specifying a switch interface to display data for all interfaces.
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.

Use the signal-to-noise ratio (SNR) and Reed-Solomon error information to measure the quality of the LRE link. The SNR represents the amount of increased received signal power (in decibels) relative to the noise power-level that the switch can tolerate without disconnecting from the CPE device. The higher the ratio, the more resilient is the link.
The Reed-Solomon errors show the number of errors detected and corrected in the data being received on and sent from the switch LRE ports. Reed-Solomon errors are the result of noise exceeding the noise margin. For short bursts of noise (such as motor power on or power surges), the interleaver prevents the loss of Ethernet data packets. The number of Reed-Solomon errors then exceeds the number of Ethernet CRC errors.
Note
The remote transmit power levels from the connected CPE devices might be different from each other, depending on how long the cable is between the switch and the CPE device. A longer cable typically causes the CPE device to send a higher signal to overcome the loss effects of distance.
The local receive-power rates actually displays the switch's adjustment to the incoming power level. These numbers might be different from LRE port to LRE port, as the length of the cables to the CPE devices might be different.
The interleaver columns display the interleaver block size for both directions of data. A higher interleaver setting is less susceptible to certain kinds of impairments but can introduce a very small amount of delay in the data path.
The PMD-S column refers to physical media dependent status and is provided as diagnostic information.
For more information about what can affect the LRE link and for the minimum required SNR ratios, refer to the "LRE Links and LRE Profiles" section in the "Configuring LRE" chapter of the switch software configuration guide for this release.
The sequence and sequence detail keywords display these status codes of profiles and sequences during rate selection:
•
•
•
•
•
You can adjust the noise level during convergence by using the margin interface configuration command.
Use the show controllers lre status cpe [interface-id] privileged EXEC command to display information about a specific CPE port or all the CPE ports.
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.
