Need some help

    Ok, here's the deal:

    I have a 6500 (6509) running IOS 12.1 with multiple VLAN's. I have an
    new 4948 running 12.2 with a blank config.

    What I want to do is attach the 4948 to the 6500 on VLAN 35
    (10.35.0.1/16) while vlan'ing out the 4948 to have a seperate vlan
    address of 192.168.10.1/24. The 4948's IP address would be 10.35.0.3.


    Connecting ports are port Gi 5/32 on the 6500 and Gi 1/48 on the
    4948. I've tried trunking the VLAN's together but I don't think I'm
    doing it right.

    Suggestions?

    Well, there isn't quite enough information here, but I'll take a
    stab. First, if your 6500 is the owner of all your other vlans, what
    is stopping you from creating your new vlan on the 6500, and trunking
    vlan 1, 35, and this new vlan. Then your 4900 will know about the new
    vlan and you can assign all of its ports as necessary, without making
    this more complicated than it needs to be.

    If for some reason the above scenario is impossible (ie there is some
    requirement that I'm not privy too) and this new subnet MUST stay on
    the new device, then you'll need to skip trunking and make sure each
    switch has an interface in the proper network (vlan 35). You'll want
    to create this new vlan on the 4948, and turn up a routing protocol to
    exchange the network information with the 6500. This way your 6500
    will have a neighbor relationship with the 4948 via 10.35.0.3 and will
    be told about the new network, and will route as necessary. Just make
    sure your 4948 is getting all of the desired routes in the other
    direction. If this is some kind of isolated VLAN, you may want to use
    a distribute list or ACL to protect that network as you see fit.

    Hope this helps...best I can do with the information you provided.
