Trying to connect a new 2960 to the Cat-5

I have a trunk port on the cat-5 connected via x-over to G0/1 on new switch

2960 Config is
vlan internal allocation policy ascending
interface GigabitEthernet0/1
 switchport trunk native vlan 100
 switchport trunk allowed vlan 1-1005
 switchport mode trunk
 spanning-tree bpdufilter enable
The port on cat-5 is showing up/up (set trunk 12/9  on dot1q 1-1005, also vlan 100)  but vlan 100 on 2960 is down  any ideas?

I have another 2960 (older) with almost identical config that is working fine.
