I'm trying to forward based on IP-precedence bits
pc--->switch--->c1700----->c3640---->3750
The 1700 successfully classifies packets with "ip-precedence critical" (5).
Next step is for Cisco 3640 to prioritize forwarding...how can I do this with a 3640 with older IOS image; this can be upgraded if necessary, but there is limited memory.
On the 3640, do I need an IOS with QOS to "trust" the ip-precedence set on the 1700 ?
Is there a simple way to have the 3640 to forward packets with ip-precedence of 5

THis is the route-map in use on the 1700...
It is definately setting the precedence, but when the 3640 gets the packet, how can I force it to read and prioritize the packet ?
route-map prior13net4 permit 20
match ip address 106 107
set ip precedence critical

If your 3640 IOS supports CBWFQ, on your outbound FastEthernet interface (assume Ethernet because of downsteam 3750), you could first try:
policy-map Yourname
interface Fastethernet 0
service policy output Yourname
or
class-map yourclassname
match precedence critical
policy-map Yourname
class yourclassname
priority # (Kbps)
interface Fastethernet 0
service policy output Yourname
