Alternative Configuration for Optics on X590, X690, X695, and X870 Switches
To use certain fiber cables and optical transceivers for stacking on X590, X690, X695, and X870 switches, you must use the V400 alternative-configuration option on the configure stacking-support command. This option sets the stacking ports to 100 Gb, enables pre-emphasis, and enables error correction using IEEE 802.3bj Clause 91 RS-FEC.
