  • Cisco Nexus 3000 Series Switches

Known Affected Releases

6.0(2)A1(1.1)

Description (partial)

Symptom:
When a Nexus 3500, configured as 'hardware profile forwarding-mode warp,' is upgraded from 6.0(2)A1(1)  to 6.0(2)A3(1), it reverts back to 'hardware profile forwarding-mode normal' and needs warp to be reconfigured, which takes another reload to fix.

Conditions:
After upgrading, you would see the issue can be verified by following command:

n3k-1# sh hardware profile forwarding-mode
===========================
 forwarding-mode : normal             <<<<<<<<<<<  should be warp as it was before upgrade.
