I need to adjust the MTU between two routers because of two encryptors in the path between the routers. The router ports are defined as 802.1Q trunked ports. The encryptor only processes layer 2 data smaller than 1420 bytes. can I use the IP mtu command in the router on a trunked interface?

but it should be
conf t
- interface
- ip tcp adjust-mss 1200

For truncks that are in between two Cisco 3750 switches, is there a way to do the same thing?
sample switch config:
interface FastEthernet1/0/33
description Trunk Connection via IPSEC INE
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,6,58,59,222,1002-1005
switchport mode trunk
speed 10
duplex full
spanning-tree port-priority 240
spanning-tree cost 5000
no shut
