I have a strange problem which i am pretty sure is quite easy to fix, because I think I am just over looking something or doing something completely dumb.
Heres the problem, I have this cisco 4507 switch that I need to configure multiple ip ranges on. The problem is that I can only configure two ip ranges on it, one ip range on the management vlan and the other ip range on vlan 2. After I have configured these 2 vlans with different ip ranges, I can route between then and get them to talk to each other, but that is all I can do. If I add another vlan with a different IP range I cannot see it from the switch or get any of the otehr ip ranges to see it.
Has anyone had this problem before. Maybe I am doing something dumb because this is a layer 4 device so it should be able to route the ip ranges. I have tried everything just cannot get it to work. I have assigned the IP range directly to the port number and directly to the vlans. Just wont work.
Remember to add the vlan to the vlan database as well. Do a show vlan and make sure it exists. Create it by typing vlan if it doesn't. And you must have a port on that vlan, and that port must be up (with a device plugged in) or it will never respond.
