I need to trunk a VLAN between a Cisco 3600 series and a cisco 3550.
I have the following configs:
Cisco 3550:
interface FastEthernet0/1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 353
switchport mode trunk
speed 100
duplex full
!
interface Vlan353
ip address xxx.xxx.xxx.62 255.255.255.252
!
Cisco 3600:
interface FastEthernet0/0
no ip address
speed 100
full-duplex
!
interface FastEthernet0/0.353
encapsulation dot1Q 353
ip address xxx.xxx.xxx.61 255.255.255.252
!
FE0/0 is directly connected to FE1/0 (test environment), however I cannot ping .61 from the 3550 or .62 from the 3600.
What am I missing here??
Thanks.

Nevermind I figured out what I did.

could be a native VLAN mismatch.
What does debug tell you?
Try creating a sub-interface on the router in VLAN 1 which is the default native vlan
interface FastEthernet0/0.1
encap dot1q 1
