I added a Vlan to my 5509 Switch,
but the vlan status is always as "vlan is down, line protocol is down" ?
How can I do to make it up?

Thanks!

A VLAN interface is defaulted in the *down* condition. You need to go though the global config ( config t), then change to the vlan interface.. then type in *no shutdown* and it should come up assuming everything else is correct.

Thanks,
The vlan is "down", but not "administratively down", so I can not up it just by typing "no shut".

I think there must be some configuration mistake, but how can I discover it?

The vlan configuration is :
interface Vlan99
 ip address 192.168.99.1 255.255.255.0
 ip verify unicast reverse-path
 no ip redirects
 mls rp vtp-domain dm
 mls rp ip

the result of "ping 192.168.99.1" is :
Success rate is 0 percent (0/5)

Can you tell me where the configuration mistake exist?

Thanks for your help.
I made a stipud mistake.
I connected 10M port assigned to that vlan to a 100M port, so they can not connected, and the vlan can not "up".
