Symptoms

The Hardware SYN Cookie Protection field is not displayed in the GUI configuration screen for TCP/FastL4/FastHTTP profiles, despite hardware support for the feature existing on the platform.

Impact

The Hardware SYN Cookie Protection field is not displayed.

Conditions

Configuring TCP/FastL4/FastHTTP profiles in the BIG-IP GUI. This occurs on vCMP guests, on the 5000/5050, 5200/5250, 7000/7050/7055, 7200/7250/7255, 10000/100050/10055, 10200/10250/10255, 10350N, i5600, i5800, i7600, i7800, i10600, i10800 platforms, and on VIPRION systems using the B4450 or B4450N blades.

Workaround

Use tmsh to set the Hardware SYN Cookie Protection field.

Fix Information

The system no longer uses a static list of platforms that have an HSB as a basis for displaying the Hardware SYN Cookie Protection option in the GUI, so the field is shown as expected.
