Each DR group can contain multiple profiles, and DR is only allowed for profiles within the same group. The table below shows the profiles listed under 10/25G Ethernet Protocol DR group and dynamic reconfiguration between these profiles is allowed. For example, you can choose to perform dynamic reconfiguration from existing "25G Ethernet + RS-FEC" to "10G Ethernet" profile and so on.
The default port profile upon power up is decided based on your selection in the subsystem GUI. If you select port 0 profile = "25G Ethernet + RS-FEC ", with dynamic reconfiguration enabled, and port 0 DR AIB mapping = port 0 (port 0 is reused after dynamic reconfiguration), when you enter the get_hssi_profile SAL command, NIOS can write the HSSI Read Data CSR with the value 7'b00000000.

The following table shows the bit encoding for 25G Ethernet and CPRI profiles under 25G Ethernet + CPRI protocol DR group. The default port profile upon power up is determined by user selection in subsystem GUI. For example, if user selects port 0 profile = "25Gbe" and RS-FEC with PTP Enabled, with dynamic reconfiguration enabled, and port 0 DR AIB mapping = port 16 (port 0 packet stream will switch to port 16 after dynamic reconfiguration), when user issues get_hssi_profile SAL command, NIOS can write the HSSI Read Data CSR with the value 7'b0010000.

The following table shows the bit encoding for CPRI profiles under CPRI protocol DR group. The default port profile upon power up is determined based on user selection in Ethernet subsystem GUI. For example, if user selects port 0 profile = "CPRI", with dynamic reconfiguration enabled, port 0 DR AIB mapping = port 0 (port 0 is reuse after dynamic reconfiguration), port 0 sub-profile 12G PCS, when user issues get_hssi_profile SAL command, NIOS can write the HSSI Read Data CSR with the value 7'b0100011.

The following table shows the bit encoding for 100/25G Ethernet profiles under 100G Ethernet protocol DR group. The default port profile upon power up is determined based on user selection in subsystem GUI. For example, if the user selects port 0 profile = "100GCAUI-4," with dynamic reconfiguration enabled, and port 0 DR AIB mapping = port 0 (after dynamic reconfiguration, the port 0 100G Ethernet packet stream will switch to port 0/1/2/3 25G Ethernet packet streams), when the user issues the get_hssi_profile SAL command, NIOS will write the HSSI Read Data CSR with the value 7'b0110000.
