I think there is 2 interfaces. Fa0/24 for trunk between swithes and fa0/1 on
sw1 is a dot1q trunk to router

Interesting question:
Try using a native vlan on one of the isl vlans.
if that doesn't work try this command
CAT1(config)#int gig 1/0/18
CAT1(config-if)#sw mo dot
CAT1(config-if)#sw mo dot1q-tunnel
CAT1(config-if)#
this tunnel is cool.
This is just a guess
CAT1(config)#int gig 1/0/18
CAT1(config-if)#sw tr en isl
CAT1(config-if)#sw mo dot
CAT1(config-if)#sw mo dot1q-tunnel
CAT1(config-if)#sw tr nat
CAT1(config-if)#sw tr native vla
CAT1(config-if)#sw tr native vlan 123
CAT1(config-if)#do srint gig 1/0/18
Building configuration...
Current configuration : 167 bytes
!
interface GigabitEthernet1/0/18
switchport access vlan 123
switchport trunk encapsulation isl
switchport trunk native vlan 123
switchport mode dot1q-tunnel
end
CAT1(config-if)#

I have isl trunk between two switches and I have a router's
fastethernet
interface split into sub interfaces and it is connected to one of
switches over a dot1q trunk. Would this work? And is there any
limitations on intermixing isl's and dot1q?
