both the sides are default to trunk mode auto. In this case there will be no trunking, just regular ISL.


Check Table 12-2

http://www.cisco.com/en/US/docs/storage/san_switches/mds9000/sw/rel_2_x/san-os/configuration/guide/trnk.html#wpxref31164


Can you configure one side to 'switchport trunk mode on'  under the FC port and check if you can get the link up as TE port?


Thanks, Vin.

ie is this a new install or you have more vsans defined on the mds switches which you have allowed on the trunk ? what does the trunk config look like ?


from both switches, please get,


show vsan

show run int fc1/2(3)


Thanks, Vin.
