What version of OS are you using? Are you still using separate CatIOS for the Catalyst and IOS for the router/L3 routing module?

Thanks

My Catalyst use

Cisco Internetwork Operating System Software

IOS (tm) Catalyst 4000 L3 Switch Software (cat4000-IS-M), Version 12.1(8a)EW1.

I know this old version, I don't know this version effect to catalyst activity .

Thanks for help me.

BTW, I'm running Cat4006 with L3 routing module (and also external 3662) router at the moment so I can most probably help you out with your problem.

Do you have any active ports in VLAN6? If not the L3 VLAN interface will shut down due to auto-state

Hi,

You need to create the vlan in the vlan database.

Please do.

conf t

vlan 1-6

state active
