"*Mar 1 02:58:32.487: vLAN: ISL packet received bearing colour ID 384 on FastEthernet0/1 which has no subinterface configured to route or bridge ID 384.
router config is:
!
interface FastEthernet0/0.38
encapsulation isl 38
ip address 162.1.38.3 255.255.255.0 "
Are you receiving this message because you're getting tagged packets on you FastE 0/1 port instead of the FastE 0/0.38 port? What does FastE 0/1 look like?

Devices connected to a medium have to agree on how they encapsulate, if
they want to communicate.
If you have only two devices, they better speak the same way!
If you have ISL, either both ends have ISL or they won't speak.
If you have 802.1Q, then you have a chance of they talking event if they
don't agree, because the native vlan is usually encapsulated without
tagging, so an "access" device can talk to a trunk native vlan.
(a routed switch interface makes an access device)
Your output sounded like the switch was configured for a trunk too, and
traffic was being sent over vlan 134. If that's not the case, please
posts the configs...
