This read-only SnmpAdminString field is the 'stepping' property of the 'GraphicsCardCapProvider' managed object in Cisco UCS Manager's equipment-inventory schema giving the silicon stepping revision of the GPU this capability entry describes. This narrows the entry down to a specific manufacturing stepping of the GPU die, since early silicon steppings sometimes have known limitations or errata that a later stepping resolves. A capability entry scoped to an early Stepping value might flag a known limitation that a later production stepping of the same GPU model no longer has.
