I have 2 CISCO 3550 - 10 2950 (doble star). Linked by 100FX.
It happens (at random) at some links are lost.
A port on the 3550 change to "ErrDisable" state.
Doing a no shutdown on the interface brings the link back up and running.
I saw that on Cisco.com:
"When a secure port is in the error-disabled state, you can bring it out of this state by entering the errdisable recovery cause psecure-violation global configuration command, or you can manually re-enable it by entering the shutdown and no shutdown interface configuration commands."
And I was wondering if the errdisable recovery cause will put back automatically my port in UP state ? And I would like to understand too why it becomes in this ErrDisable state ?
