Trunking has to do with carrying multiple tagged vlans on one port - and 
the 2900xl with a 12.x IOS should do that in either ISL (cisco) or dot1q 
  mode.  But I thought we were grouping ports instead.  You should be 
able to do both, but the interfaces in the same port group would have to 
have the same trunk encapsulation set.  There is a separate 'vlan 
database' command on those switches where you have to add the vlan 
numbers that you want a trunk to carry - and it doesn't get saved in the 
visible config file.  If you have 'switchport access vlan nnn' on any 
interface that number goes in the vlan database automatically but you 
just want the trunk ports to pass some other vlans through you have to 
add them explicitly.
