some ports issue on switch after upgrading the switch OS6900-T40

Hello All,

after upgrading the switch OS6900-T40 with latest version 8.9.107.R02 GA , one system admin complaining that his vnic are not communication with vcenter and this is with some ports but on same switch there are other vnic which are also communication with vcenter and those working fine.

i am not understanding why it is happening with this switch after upgrading because previously no one were reporting the issue.

can anyone help me on this. and let me know if any command output required.
