Great. 
Also, you can do this using CLI commands:
conf t -&gt; trunk protocol enable #to enable trunking protocol
conf t -&gt; no trunk protocol enable #to disable trunking protocol
trunk protocol auto #to set trunking in auto mode . The preferred conf for CISCO MDS switches is (on)  (auto) - one switch enabled, second is auto.
1. Connect 2 switches with FC cable on ANY port
2. In each switch, change port mode to TE:
show interface fc1/1
or
show running-config interface 1/1 # to see a current configuration
config t -&gt; interface fc1/1 -&gt; switchport mode auto /on /off #will automatically set the port in TE mode in case it was previously set in another mode

3. Trunking ports should remain in  VSAN1
4. Create new VSAN (same name and number) on both switches.
5. On both switches, run:
config t -&gt; interface fc1/1 -&gt; switchport trunk allowed vsan 2-4 #To configure an allowed-active list of VSANs for an interface
switchport trunk allowed vsan add 6 #Expands the specified VSAN 6 to the new allowed list
no switchport trunk allowed vsan 2-4 
no switchport trunk allowed vsan 5

One important note: you should create a VSANs BEFORE you allowing trunking on them - otherwise trunking port will be automatically disabled due to VSAN mismatch. Same problem can occur, if trunking interfaces are located in different VSANs (for example, fc1/1 on switch A is in VSAN 2, while fc1/9 on switch B is in VSAN 3).
