What needs to be validated

For a bug validation, describe the bug ID (ex. CSCxx12345) and the brief description of the bug in the context of pre-upgrade validations. [CSCwf00416] ACI 16.0.2 leaf sends manually configured intf description as port description in lldp instead of dn

  1. Check if there are any interface profile that has a desc configured. If there is one then we need to find our if that interface profile is tied to a VMM doamian moquery -c infraAccPortP | egrep "^dn|desc"

  2. Get a list of all the vmm domain that has on demand attachment. This issue affects only vmm doamin with on demand resolution a-apic1# moquery -c fvRsDomAtt | egrep -B 16 "instrImedcy : lazy" | grep "dn.vmmp"

  3. Find the AEP associated with vmm domain. This will help get the policy group tied to the AEP. a-apic1# moquery -c infraRtDomP | grep ^dn | grep vmmp

  4. get the policy group associated with the specfic VMM AEPs a-apic1# moquery -c infraRtAttEntP | grep ^dn

  5. See which Interface Profile has the specfic policy group associated with the VMM AEPs and whether there is a description associated with that profile a-apic1# moquery -c infraAccPortP -x rsp-subtree=full | egrep -A 18 "infra.AccPortP|infra.RsAccBaseGrp" | egrep "^dn|^desc|^ dn|^ tDn"

  6. If there is description associated with that profile then we need to flag it.

Why it needs to be validated

Vlans will not be deployed on the leaf

Since issue is only in 6.0.1 and 6.0.2 which customers should not be targeting today, we will do simple check for VMM domain=lazy and custom interface descriptions exist. Check is still necessary due to the severity of the issue.
