Configuring LRE Ports
To return the switch to its default setting, use the no lre upbo {noise-model | offset value} global
configuration command.
Configuring CPE Toggle
The CPE toggle feature is enabled by default. It cannot be disabled on a link from a Cisco 575 LRE or
Cisco 576 LRE 997 CPE to a remote Ethernet device (such as PC).
You can disable CPE toggle on a Cisco 585 LRE CPE link. Then the CPE Ethernet link does not
transition to the up state when the LRE link comes up.
Beginning in privileged EXEC mode, follow these steps to disable CPE toggle on a Cisco 585 LRE CPE
link:
To re-enable CPE toggle on the Cisco 585 LRE CPE link, use the cpe toggle [port port-id] interface
configuration command.
Configuring Syslog Export
If the syslog export feature is enabled, the switch sends the debugging messages to the LRE message
logging process and to the system message logging process.
Before enabling this feature, follow these guidelines:
• Make sure that LRE logging is enabled.
• Make sure that the console severity in the system message logging configuration is set to debugging.
For more information, see Chapter 27, “Configuring System Message Logging.”
