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.
