FPGA Firmware Selection
The Cisco Nexus 3550-T Programmable Switch Platform uses reconfigurable FPGA technology to provide switching functionality. The device ships with a number of different FPGA firmware images, each of which provides a different set of functionality. Users can choose the FPGA firmware image that is best suited for their use case.
Selecting the FPGA firmware image
Beginning from NX-OS Release 10.6(3)F, 3550-T supports 25G on the first 40 front panel ports. In configuration mode, the command allows the N3550-T to be converted into a TOR switch working in 1/10G mode with 48 front panel ports or it can be converted to a TOR switch working in 25G mode with 40 front panel ports in first release with the last 8 ports as disabled.
This command allows the users to switch between 10G and 25G.
admin@NX-3550-T(config)# system interface speed [10g | 25g]
Note
Beginning with NX-OS Release 10.6(3)F, FEC is not supported in 25G mode.
