on the 6509-E I have created few vlans which are working fine, this 6509-E is the vtp server and other switches are connected to it working as vtp client. Recently I add another vlan on 6509-e which was connected to a new switiches. the new switch I configured is just like another switches I had done before.

strangly the new vlan which I created on 6509-E does not seems to be coming up , when checked on 6509-e the  interface is down, line protocol is down.

    You're confusing a VLAN with a VLAN interface.

    A VLAN interface will not be UP/UP unless the VLAN exists.

    Do a "show vlan brief" and make sure it exists.

    When you are configuring VLANs and you assign IPs to the VLAN interfaces dont forget the no shut interface command

    thanks ppl,

    I figured it out... suppose to do the following after the vlan interface is configured

    (config)# vlan "vlan number"

    and simply type exit.

    That's what I said: "Make sure the VLAN exists". What you did was create the VLAN.

    What's the right grade to give?        
    Grading at Experts Exchange is not like school. It's more like the "10-point Must" system in professional boxing; in other words, an answer is worth an A, unless it doesn't resolve your issue. If it requires you to do a little more research, or figure out one more piece of code, then it's worth a B. If you think it's not worth a B, the custom is to offer the Experts an opportunity to earn a better grade.

    Giving a higher grade has no impact on your Available Points.
