Given the following configuration：  port-profile type ethernet DATA-UPLINK   vmware port-group  switchport trunk allowed vlan 1-3967，4048-4093  channel-group auto mode on  no shutdown  state enabled  port-profile type ethernet MGMT-UPLINK  vmware port-group    switchport trunk allowed vlan 10-12  channel-group auto mode on  no shutdown  state enabled       VEMs are seen to be joining and then are lost from the Cisco VSM. How would you resolve this issue？（）

• A、 Remove second NIC from each port profile
• B、 Remove VEM from VSM （no vem X）， remove NICs， and reinsert
• C、 Ensure that VLANs on uplink profiles are not overlapping
• D、 Reinstall VEM
• E、 Issue the command "module vem X execute vemcmd set pinning module vsm 1"
