Cisco Bug: CSCvi78178 - SUP-1 and SUP-1XL should not form HA

Last Modified

Sep 18, 2018

Products (1)

  • Cisco Catalyst 9400 Series Switches

Known Affected Releases

16.8.1

Description (partial)

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

Conditions:
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.
