debugging of Long-Reach Ethernet(LRE)-related events.Use the no form to disable debugging.debug lre [controller | errors | profile | state] [interface-id]no debug lre [controller | profile | state]Syntax Description controller Display the customer premises equipment (CPE) Ethernet interface controlaccess and CPE timing information.errors Display certain types of unexpected events that mean that the switch isconfigured or operating in a nonstandard way.profile Display profile management events on the switch.state Display state transition events of each switch LRE port.interface-id

was extended to support the Cisco 585 LRE CPE.Usage Guidelines If you use the debug lre command without providing a specific debug option, all LRE debug options areenabled.Conversely, if you use the no debug lre command without providing a specific debug option,all LRE debug options are disabled.You can enable and disable the LRE debug options on individual ports, for example, by using the debuglre state interface-id command.If a specific port is not provided, the debug option applies to all switchLRE ports.To troubleshoot LRE connectivity problems, use the debug lre state command to display the statemachine transitions and the debug lre errors command to display other information that might explainunusual occurrences that could be affecting connectivity.Catalyst 2900 Series XL

should run in full- or half-duplex mode.Defaults For 10/100, 100BASE-FX, and Gigabit ports, the default is auto.Command Modes Interface configurationCommand History Release Modification11.2(8)SA This command was first introduced.12.0(5)WC1 This command was extended to support the Cisco 575 LRE CPE.12.0(5)WC4 This command was extended to support the Cisco 585 LRE CPE.Usage Guidelines Certain ports can be configured as either full duplex or half duplex.Applicability of this commanddepends on the device to which the switch is attached.For Fast Ethernet ports, setting the port to auto has the same effect as specifying half if the attacheddevice does not autonegotiate the duplex parameter.For Gigabit Ethernet ports, setting the port to auto has the same effect as specifying full if the attacheddevice does not autonegotiate the duplex parameter.If the speed is set to auto, the switch negotiates with the device at the other end of the link for the speedsetting and then forces the speed setting to the negotiated value.The duplex setting remains asconfigured on each end of the link, which could result in a duplex setting mismatch.If both the speed and duplex are set to specific values, autonegotiation is disabled.This command is not supported on the ATM module.For CPE Ethernet ports, the default is half duplex with back pressure.You can change the duplex settingon the Cisco 575 LRE CPE, but not on the Cisco 585 LRE CPE.Duplex autonegotiation is supported onthe Cisco 575 LRE CPE, but not on the Cisco 585 LRE CPE.Note For guidelines on setting the switch speed and duplex
