to recover from it, and provides examples of errdisable recovery. This document uses the terms errdisable and error disable interchangeably. Customers often contact Cisco Technical Support when they notice that one or more of their switch ports have become error disabled, which means that the ports have a status of errdisabled. These customers want to know why the error disablement happened and how they can restore the ports to normal. Note: The port status of err-disabled displays in the output of the show interfaces interface_number status command. Prerequisites Requirements There are no specific requirements for this document. Components Used In order to create the examples in this document, you need two Cisco Catalyst 4500/6500 Series Switches (or the equivalent) in a lab environment with cleared configurations. The switches should run Cisco IOS® Software and each switch should have two Fast Ethernet ports that are capable of EtherChannel and PortFast. The information in this document was created from the

Yasir Irfan Profile: Yasir Irfan Link flap means that the interface continually goes up and down in a Cisco Switch. The interface is put into the errdisabled state if it flaps http://itknowledgeexchange.techtarget.com/network-technologies/what-is-the-link-flap-error-in-cisco-switches/ more than five times in 10 seconds. The common cause of link flap is a Layer 1 issue such as a bad cable, duplex mismatch, or bad Gigabit Interface Converter (GBIC) card. Look at the console messages or the messages that were sent to the syslog server that state the reason for the port shutdown. 13w0d: %PM-4-ERR_DISABLE: link-flap error detected on Fa0/28, putting Fa0/28 in err-disable state Issue this command in order to view the flap values: SRCL-ONC-3550-AS01# sho errdisable flap-values ErrDisable Reason Flaps Time (sec) ----------- ---- -------
