Resolution

In order to configure the maximum number of flaps that are allowed to occur before setting to error disable (errdisable), use the errdisable flap-setting cause command.

Cisco recommends not to change the default values.

But you can change the flap-values. If you want to change the flap-values, try these commands:

3750(config)#errdisable flap-setting cause link-flap max-flaps 2 time 15

3750#show errdisable flap-values
ErrDisable Reason  Flaps   Time (sec)
-----------------  ------  ----------
pagp-flap          3       30
dtp-flap           3       30
link-flap          2       15 

Note: You must enter the shutdown command and then the no shutdown command in order to recover an interface manually from errdisable.
