Problem with NPE-G1

Hello I've Cisco 7206VXR (with NPE-G1) router connected to Catalyst switch over copper 1000BaseT connection. Every time When I'm adding subinterface at Gi0/1 the whole Gi0/1 went, eg:

conf t int giga0/1.200

Then on switch:

%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/1, changed state to down %LINK-3-UPDOWN: Interface GigabitEthernet0/1, changed state to down %LINK-3-UPDOWN: Interface GigabitEthernet0/1, changed state to up %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/1, changed state to up

Configuration:

interface GigabitEthernet0/1 no ip address duplex full speed 1000 media-type rj45 no negotiation auto no cdp enable no clns route-cache

interface GigabitEthernet0/1 switchport trunk encapsulation dot1q switchport mode trunk load-interval 30 speed 1000 duplex full no mdix auto no cdp enable end

Earlier Giga0/1 was connected to other Catalyst over 1000BaseSX (using SX GBIC at NPE-G1) connection - and earlier there was no problem...

Thanks, RobertH
