you need to setup a trunk.

On both Ports connecting the 3750 and 3500.

#switchport mode trunk

switchport trunk encapsulation dot1q

switchport nonegotiate

if you want to setup etherchannel, meaning aggregate 2 or more ports into 1 logical add this to all ports on the above config.

#channel-group 1 mode on

Do this to make sure you have a trunk properly setup on the etherchannel.

You don't have to set up a trunk if you are just running 1 vlan down the pipe , just use the etherchannel commands if this is the case .

The 3500 side will look like this

interface FastEthernet0/1

port group 1

!--- The port group command

!--- makes this interface a member of channel group 1.

!

interface FastEthernet0/2

port group 1

!--- This interface is also a member of channel group 1.
