Re: Catalyst 4006 ,Interface VLAN down,

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

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.

Re: Catalyst 4006 ,Interface VLAN down,

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

end
