Environment
NI 6.0g
NI 6.0h
Cause
Upon a reload the Topology table is not initialized correctly causing memory Parity Errors in the second tower of Gen 2 cards
Resolution
Work Around:
  1. Physically move links to 1st Tower of card; ports 1-4 on BR-MLX-10Gx8-X
    1. No reload is required, ports should come up immediately
  2. Check if the primary port is untagged on a VLAN (by default VLAN1)
    1. If the untagged VLAN is participating in RSTP, the ports can be forced to LACP-BLOCKED 
    2. Remove untagged VLAN association
  3. Remove RSTP from any VLAN with Untagged ports

Resolution:
  1. Upgrade/Downgrade to any version other than 6.0g or 6.0h
