Unable to add/remove/edit port mirroring sessions in vSphere 8.0

Products

• VMware vSphere ESXi 8.0
• VMware vCenter Server 8.0

Issue/Introduction

• After upgrading vSphere to 8.0, adding, removing, or editing port mirroring sessions fails with the following error, “A specified parameter was not correct: port[###] cannot be add/edit here, for it was used by same or other sessions”. (The port number can vary, depending on the environment)
• This may occur with Gigamon or other third-party monitoring solutions when an orphaned session is left behind.
• When trying to remove a specific session, which is the port mirror it fails with error: "A specified parameter was not correct: port[####] can not be add/edit here, for it was used by same or other sessions"

• The /var/log/vmware/vpxd/vpxd.log file on vCenter reports the error below related to the port mirroring session when trying to edit it:
  

  YYYY-MM-DDThh:mm:ss.890Z error vpxd[11075] [Originator@6876 sub=Default opID=########] [VpxLRO] -- ERROR task-######## -- ################(########################) -- dvs-

  -->    faultMessage = <unset>,
  -->    invalidProperty = port[###] can not be add/edit here, for it was used by same or other sessions"
  -->    msg = ""
  --> }

Environment

VMware vSphere 8.0

Cause

This is expected behavior in vSphere 8.0 as "A source mirroring port cannot be used in more than one mirroring session"
