FPGA Profile
The FPGA Profile feature turns certain software features assisted by field-programmable gate array (FPGA) on or off. Some switch features such as Parallel Redundancy Protocol (PRP), High-Availability Seamless Redundancy (HSR), Device Level Ring (DLR), and Cisco TrustSec (CTS) rely heavily on FPGA implementation. FPGA Profiles allow for efficient allocation of platform resources for the operation of multiple time sensitive, resilient industrial protocols without changes to hardware.
Note |
FPGA Profiles are supported only on Cisco IE3400 and IE3400H Series Switches. FPGA Profiles are applied globally to the base switch. If an expansion module is present, it uses the same FPGA Profile as configured for the base switch. |
The switch supports three FPGA profiles with different combinations of features supported in each profile, as shown in the following table.
