Off the top of my head: I believe the Cisco plugin only sends the
"switchport" and "switchport mode trunk" commands if the port isn't
already in trunking mode.  Were there any vlans already configured on
the port in question before you created a network?  If not, you may be
running into:

https://bugs.launchpad.net/quantum/+bug/1174852

There's a workaround mentioned in the bug.
