Description (partial)

16.8.1 and earlier releases allow SUP-1 and SUP-1XL to form SSO hot state.

When SUP-1 and SUP-1XL are present in the same chassis, 16.8.1 and earlier releases form HA with these two different supervisor types. SUP-1 and SUP-1XL have different capabilities and forming HA and triggering switch over will lead to undefined system behavior.
