Hello,
Just an informational post to maybe save some one some time.
We recently updated from 3.1(1e) to 3.2(3a). In the process of doing so our pVlan's quit forwarding ARP broadcast traffic to vMware guests. After much trouble shooting and insistence from TAC that something must be misconfigured upstream of the UCS FI we finally rebuilt the UCS pVlan's and magically ARP broadcast traffic began to flow again. No need to delete the vlans just remove them from the vNIC's and set all Primary and Secondary vlans to normal vlans and commit the config, then rebuild the Primary/Secondary constructs and reapply to vNIC's.
