I need ADX 12.4 G code, where i can download it.
The firmware codes including ADX 12.4 can be downloaded on mybrocade in the link below. Once you login, go to Downloads-> Select 'Application Delivery Controllers' in the pulldown menu-> ServerIron ADX-> 12.4
You may further post your ADX questions under "Application Delivery" Forum on Brocade Community. This forum is for discussing L2 switches such as fastIron.
