I try to add C2950 on C3550

I have %LINK-4-ERROR on both side.
The light of C3550 uplink port is flashing green-amber

this is the port config on C2950:
interface FastEthernet0/1
description vers trb491sw2 491 des seigneurs
switchport trunk native vlan 12
switchport trunk allowed vlan 1,12,145,1002-1005
switchport mode trunk
speed 100
duplex full

this is the port confgi on C3550:
interface FastEthernet0/23
description vers trb491sw5
duplex full
speed 100
switchport trunk native vlan 12
switchport trunk allowed vlan 1,12,145,1002-1005
switchport mode trunk

this is the sh interface result on C2950:
