Happened automatically once I configured the VLAN and port config and tagging on the other end of the VLT!  Thanks for the trigger about the "orphaned" port.  
I'm not a network engineer, but am trying to set one port on my MXL switch to a VLAN which will route traffic out from virtual machines to a local compute network.  It's port Te 0/52 on the back of the MXL and I'm running ESXi on the servers in my m1000e.  I actually have two MXLs in the A fabric of the m1000e configured with VLT over the FourtyGig interfaces.  That part was set up by the Dell Tech Services folks who did the install.  Here is what the config looked like to start: dsa1#show vlanCodes: * - Default VLAN, G - GVRP VLANs, R - Remote Port Mirroring VLANs, P - Primary, C - Community, I - Isolated       O - OpenflowQ: U - Untagged, T - Tagged   x - Dot1x untagged, X - Dot1x tagged   o - OpenFlow untagged, O - OpenFlow tagged   G - GVRP tagged, M - Vlan-stack, H - VSN tagged   i - Internal untagged, I - Internal tagged, v - VLT untagged, V - VLT tagged    NUM    Status    Description                     Q Ports*   1      Active                                    U Po33(Fo 0/33,37)                                                     U Po41(Te 0/41-44)                                                     U Te 0/1-32    115    Active    Mgmt                            T Po41(Te 0/41-44)                                                     V Po33(Fo 0/33,37)                                                     T Te 0/1-32    486    Active    VMGuest                         T Po41(Te 0/41-44)                                                     V Po33(Fo 0/33,37)                                                     T Te 0/1-32                                                     U Te 0/49-50 And I wanted to add VLAN 1000 for compute, so I did the following: dsa1#conf dsa1(conf)#interface Te 0/52dsa1(conf-if-te-0/52)#show config!interface TenGigabitEthernet 0/52 no ip address mtu 12000 portmode hybrid switchport flowcontrol rx on tx off spanning-tree rstp edge-port bpduguard shutdown-on-violation no shutdown dsa1(conf)#interface vlan 1000dsa1(conf-if-vl-1000)#show config!interface Vlan 1000 description Compute name Compute no ip address tagged TenGigabitEthernet 0/1-32 untagged TenGigabitEthernet 0/52 no shutdown VLANs now look like: dsa1#show vlanCodes: * - Default VLAN, G - GVRP VLANs, R - Remote Port Mirroring VLANs, P - Primary, C - Community, I - Isolated       O - OpenflowQ: U - Untagged, T - Tagged   x - Dot1x untagged, X - Dot1x tagged   o - OpenFlow untagged, O - OpenFlow tagged   G - GVRP tagged, M - Vlan-stack, H - VSN tagged   i - Internal untagged, I - Internal tagged, v - VLT untagged, V - VLT tagged    NUM    Status    Description                     Q Ports*   1      Active                                    U Po33(Fo 0/33,37)                                                     U Po41(Te 0/41-44)                                                     U Te 0/1-32    115    Active    Mgmt                            T Po41(Te 0/41-44)                                                     V Po33(Fo 0/33,37)                                                     T Te 0/1-32    486    Active    VMGuest                         T Po41(Te 0/41-44)                                                     V Po33(Fo 0/33,37)                                                     T Te 0/1-32                                                     U Te 0/49-50    1000   Active    Compute                         T Te 0/1-32                                                     U Te 0/52 But I wanted  to add VLT tagged Po33 to the new VLAN because it exists in the others, not because I really understand what it does.  I believe it's used for load balancing?  If I tag it with the command "tagged Po33" under the vlan config it comes out with status "T" instead of "V" Here's the details of VLT:   dsa1#show vlt detailLocal LAG Id  Peer LAG Id  Local Status  Peer Status  Active VLANs------------  -----------  ------------  -----------  -------------41            41           UP            UP            1, 115, 486dsa1#show vlt brief VLT Domain Brief------------------ Domain ID:                      100 Role:                           Secondary Role Priority:                  4096 ICL Link Status:                Up HeartBeat Status:               Up VLT Peer Status:                Up Local Unit Id:                  0 Version:                        6(4) Local System MAC address:       f8:b1:56:09:70:b1 Remote System MAC address:      f8:b1:56:09:70:fd Configured System MAC address:  00:01:00:01:00:01 Remote system version:          6(4) Delay-Restore timer:            90 seconds Delay-Restore Abort Threshold:  60 seconds Peer-Routing :                  Disabled Peer-Routing-Timeout timer:     0 seconds Multicast peer-routing timeout: 150 seconds So my questions are, am I on the right track?  Will this do what I want it to do which is send traffic out port Te 0/52 which is tagged in ESXi with VLAN 1000?  Do I need to worry about the VLT tagging stuff and if so, how do I do the VLT Tagging rather than normal tagging?
