Problem after Upgrade to 4.2(4k) - VMM Enhanced LAG Policy

Hello, 

 

we recently updated the ACI fabric from version 3.2 (3n) to 4.2 (4k)

 

After that the following behavior occurs:

Associating an EPG with a physical domain works and all systems within the EPG can communicate with each other.

Association an EPG with a given VMM domain works but systems within the EPG can't communicate with each. 

 

All other EPGs which was assigned to a VMM domain before the upgrade works also fine. 

 

We got the following error: 

Affected    : comp/prov-VMware/ctrlr-[DVS-Production]-VCSA_Production

Cause       : oper-issues

Description : Operational issues detected on EnhancedLag Policy: lag1 in 

             VM Controller:VCSA_Production, VM Domain:DVS-Production, VM Provider:VMware,

             error: Cannot find a lacpEnhancedLag policy in the domain   

             for the EnhancedLag policy on the DVS   

 

Also I noticed since version 3.2(7n) there is a requirement for using Enhanced Lag Policy when VDS is > Verison 6.6

Currently we don't have an enhanced LAG Policy.

 

My questions: 

  • What happens if we create an Enhanced LAG Policy under the vSwitch Policy? 
  • What happens if we assign the new Enhanced LAG Policy to the EPG within the VMM association?
