Interfaces that will be enabled at the next timeout:


Interface    Errdisable reason    Time left(sec)
---------    -----------------    --------------
          Lo0/16             link-flap   256
          Lo0/21             link-flap   258


LRE-Switch-20#show interfaces status err-disabled


Port      Name               Status       Reason
Lo0/16    **** 970 ****      err-disabled link-flap
Lo0/21    **** 975 ****      err-disabled link-flap


interface LongReachEthernet0/16 + 21
description **** 970 ****
switchport protected
spanning-tree portfast





The following LRE interfaces are erroring out on this switch.  What causes an interface to error out on an LRE interface?


I know how to clear the error reseting the interface, but how can I resolve this issue?


Thanks.

  It tells right in your display . The links are flapping excessively so the switch err-disables them .  This would have to be fixed to get this to stop.
