Resolved this, please disregard. 
 Hi  We have the same problem across 3 different M1000e chassis. Fabric A is populated with M6220, Fabric B with M8024 switches. All the internal ports on the 3 chassis report as down. i have cycled through a shutdown and no shutdown for the ports, but that has had no effect. the external ports which i interface with external switches on the top tier, do come up fine when the cable is connected. the internal ports however, give no joy.  i am quite perplexed by the fact that these ports are internal, so there is no issue of cabling or damaged connectors. besides, all three chassis reporting this at the same time. all the ports on all the switches could not be bad. Am i missing something here. the internal ports are all trunked for multiple VLANs. If i look through the Web-GUI, it shows Admin status as "Disabled". when i change it to enabled, and refresh the page, it reverts to disabled. copy run start after enabling it, makes no difference either. would really appreciate any pointers anyone could lend.  thanks.
